If pretrace_start is set below pretrace_end, POV-Ray will run a high number of pretrace steps (without changing pretrace resolution).

‘povray -H10 -W20 myscene.pov’ will generate a file with a picture 10 pixels high and 20 pixels wide, BUT in the message pane it displays

Image resolution.....20 by 10 (rows 1 to 20, columns 1 to 10)

instead of

Image resolution.....20 by 10 (rows 1 to 10, columns 1 to 20)

or

Image resolution.....20 by 10 (columns 1 to 20, rows 1 to 10) 

polygon objects comprised of multiple “sub-polygons” don’t work properly if start/end points of sub-polygons do not exactly match, as can be demonstrated by the following code:

#default { texture { pigment { rgb 1 } finish { ambient 1.0} } }

camera {
  orthographic
  up 3.5*y
  right 3.5*x*image_width/image_height
  location  <0,0,-4>
  look_at   <0,0,0>
}

polygon { 8,
  // outer triangle
  0.70 * < cos(  0 *pi/180),sin(  0 *pi/180),0>
  0.70 * < cos(120 *pi/180),sin(120 *pi/180),0>
  0.70 * < cos(240 *pi/180),sin(240 *pi/180),0>
  0.70 * < cos(360 *pi/180),sin(360 *pi/180),0>

  // inner triangle
  0.35 * < cos(  0 *pi/180),sin(  0 *pi/180),0>
  0.35 * < cos(120 *pi/180),sin(120 *pi/180),0>
  0.35 * < cos(240 *pi/180),sin(240 *pi/180),0>
  0.35 * < cos(360 *pi/180),sin(360 *pi/180),0>
}

Note that the end points /should/ be identical. There are however some minor rounding differences, which mess up polygon computations. Compare with the following code, which leads to the desired results:

polygon { 8,
  // outer triangle
  0.70 * < cos(  0 *pi/180),sin(  0 *pi/180),0>
  0.70 * < cos(120 *pi/180),sin(120 *pi/180),0>
  0.70 * < cos(240 *pi/180),sin(240 *pi/180),0>
  0.70 * < cos(  0 *pi/180),sin(  0 *pi/180),0>

  // inner triangle
  0.35 * < cos(  0 *pi/180),sin(  0 *pi/180),0>
  0.35 * < cos(120 *pi/180),sin(120 *pi/180),0>
  0.35 * < cos(240 *pi/180),sin(240 *pi/180),0>
  0.35 * < cos(  0 *pi/180),sin(  0 *pi/180),0>
}

Code inspection shows that the polygon insideness testing code tests for precise equality of the points, whereas the general policy of POV-Ray is to accept slight rounding differences.

I rendered attached .pov file with both 3.62 and 3.7RC1, and got different output between them.
In 3.7RC1, it looks like no_reflection option of the black sphere doesn’t work.

Using interpolated image_maps in functions results in pixel-sized dot-artifacts when using the functions back into pigments.

This problem doesn’t shows using the same code on POV-Ray 3.6.

I qualified it as “low severity” because is not going to happen to most users: it will show only when using some advances techniques, for example when you want to decompose an image_map into the RGB components, perform operations, and mixing them back with an averaged pigment (example attached).

The documentation says:

“-J Sets aa-jitter off”

However, it seems to have no effect. -J0 will turn off jittering.

Given the following two statements, a missing closing brace in the function declaration fn should throw a parse exception; instead it causes a memory access violation when trying to use fn in the second delcaration:

#local fn = function { 
  pigment { image_map { png "MultiPassBlobs3.png" gamma 1 map_type 0 once }} 
#local clr = fn(0,0,0);

original post on povray.beta-test:

POV-Ray 3.7.0.RC3 on Slackware 13.0 x86_64.
I pointed povray to use the calibri.ttf font over on my Windows 7 partition.
The result is garbled - strange letters with accents appear instead of the
expected text. (KDE's kfontview opens calibri.ttf OK, with nothing strange).

Pointing povray to use other fonts of Win7, e.g. comic.ttf and arial.ttf, was
OK.

I solved the problem by pushing calibri.ttf through fontforge and resaving it
as mycalibri.ttf.

Cheers,
Peter

Confirmed with development version on Windows XP x64.

Possibly a similar problem as  FS#162 .

A scene of a hollow sphere viewed from the inside:

difference {
    sphere { 0, 100 }
    sphere { 0, 99 }
    pigment { rgb 1 }
    finish { ambient .4 }
}

global_settings {
    radiosity {
        error_bound .1
    }
}

Rendering produces dark splotches at the centers of the pretrace blocks, as shown in the attached image. Blocks rendered earlier have darker splotches. They also differ in shape between renders even with +HR (but not with +WT1).

Turning “always_sample” on, changing “pretrace_end” to 0.01, or increasing “count” past 1000 makes them imperceptibly faint (they can still be seen by increasing image contrast).

This is possibly a bug, as 3.6 doesn’t produce these artifacts regardless of additional settings.

povray.beta-test thread

#macro A()
  #local foo = function { x }
  foo
#end

#local bar = A();

This causes either a segfault, corruption detected by malloc, or “Parse Error: Unknown user defined function”.

After some debugging I think this is what happens.

In source/backend/parser/parse.cpp, Parser::Parse_RValue is called to define the value of bar. Get_Token is called, which invokes A() and which ultimately returns foo as a FUNCT_ID_TOKEN. This token is handled by CASE_VECTOR in Parse_RValue. The relevant clause calls Parse_Unknown_Vector to parse additional tokens (e.g. “foo ( 1 )”). There aren’t any other tokens, but in the process of determining that, #end is reached and Return_From_Macro destroys the symbol table of A, including foo.

So by the time the CASE_VECTOR clause decides that foo is a function identifier that should be copied, the function is destroyed (both the function itself and its number in the symbol table). So here:

    Temp_Data  = (void *) Copy_Identifier((void *)*Token.DataPtr,*Token.NumberPtr);

if *Token.DataPtr (in this case, a function index) was already overwritten, we get “Unknown user defined function”; if it still has the valid function number, it increments the reference count of the function (which has already been freed) back from 0, and we get a double-free later.

A similar problem occurs when foo is a spline.

A tentative patch for the function case is attached.

in change #3319, csg got a new computation for its weighted textures.

But I’m confused by the computation of the weight: (circa end of csg.cpp file)

COLC weight = 1.0f / min(COLC(textures.size() - firstinserted), 1.0f);

I would have used a max() rather than a min().

It is transparent when there is only one texture, but:

• should there be no texture (an error...): it would be a division by 0
• should there be more than 1, the weight of each would be 1. which is without consequence UNLESS there is already some other textures in the list. The right value (from previous code) was 1/n

Or did I get a confusion about min() ?

min(0,1) == 0
min(4,1) == 1

Using max would protect against the division by 0 and the right value when multiple textures are used.

Any thought ?

UV-mapped textures for parametrics are broken in POV-Ray 3.70 RC3, in cases where two (or more) parametrics overlap in a scene.

In the following scene, note how the texture per se is always taken properly from whichever parametric is in front, while the UV coordinates are erroneously taken always from the red parametric where both overlap, no matter whether it is in front or back.

camera {
  location  <0.0, 1.5, -3.0>
  direction 1.5*z
  right     x*image_width/image_height
  look_at   0
}

light_source { <-30, 30, -30> color rgb 1 }

#declare Param = parametric {
  function { u*v*sin (15*v) },
  function { v },
  function { u*v*cos (15*v) }
  0, 1
  contained_by { box { -1,1 } }
  accuracy 0.002
  precompute 15 x,y,z
  rotate 180*x
  translate  <0.3,0.5,0>
}

object {
  Param
  uv_mapping
  texture {
    pigment {
      gradient x frequency 3
      color_map {
        [0 color red .5 ]
        [1 color red 1 ]
      }
    }
  }
}

object {
  Param
  uv_mapping
  texture {
    pigment {
      gradient x frequency 7
      color_map {
        [0 color green .5 ]
        [1 color green 1 ]
      }
    }
  }
  rotate y*180
}

POV-Ray 3.62 renders the scene properly.

As this bug has been found during code inspection, the uderlying cause has already been identified; I’m currently working on a fix.

Hello,

this bug report relates to this thread: http://news.povray.org/povray.beta-test/thread/%3Cweb.4e0064d9a3970d212b256d410%40news.povray.org%3E/

In /unix/unixoptions.cpp around line 817:

while ( !Stream.eof() )
{
	// get and preprocess line
	std::getline(Stream, line);
	line = pre_process_conf_line(line);
	++line_number;
	// skip empty line
	if(line.length() == 0)
		continue;
        [...]
}

`Stream.eof()` could never be true as well as `line.length()` always can be zero, leading to an endless loop. In my case, the problem occurred due to my ~/.povray/3.7/povray.conf being a directory instead of a file.

To fix the problem, one has to consolidate this loop by not only checking for eofbit, but also for failbit and badbit of `Stream`. The getline() method on a directory does not set the eofbit, but it sets fail and bad (test: http://codepad.org/RiZGo3ia). According to http://www.cplusplus.com/reference/iostream/ios/operatornot/ fail and bad can be checked for by `!Stream`. A simple `if (!Stream) break;` within the loop fixes the problem (patch file attached).

Are there more missing checks on iostreams like this in the code? :) They should definitely be fixed.

Furthermore, one could think about using the boost filesystem library to be able to distinguish files and directories to provide good error messages.

Hope that helps,

Jan-Philip Gehrcke

Certain types of errors are being reported twice. For example:

Parse Error: Expected ‘numeric expression’, } found instead
Parse Error: Expected ‘object’, undeclared identifier ‘foo’

The first error was a user typo when not enough parameters were specified, and the later when calling a yet to be declared object.

During investigation it was also discovered that improperly formed scale statements also produced the double error report: <scale 1,0.5,1>

Verified on linux and windows platforms.

in the sample scenes, animations/raddem/raddem.ini is not parsable by current versions of povray. (3.7RC3 and upto #5476)

Radiosity= is a gone away option.(from a bit of time in the 3.7 branch)

The following SDL code causes a hard crash during parsing if _3024_dot_dat is undefined:

light_source {
    <0, 0, 0>
    color rgb 0.5*<1,0.905882,0.211765>
    fade_distance 500
    fade_power 1.6
    looks_like {_3024_dot_dat texture {
        pigment { rgbf <1,0.905882,0.211765,0.90> }
        finish { ambient 0.6 diffuse 0 phong 0.5 phong_size 40
            reflection 0.9
            refraction 1 ior 1.25
            }
        }
}    } 

The following scene reders differently with POV-Ray 3.7.0.RC3 than with POV-Ray 3.6.2:

camera
{
    right x*image_width/image_height
    location  <0, 0, -5>
    look_at   <0, 0, 0>
}

light_source
{
    <0,0,0>
    color rgb 1
    looks_like
    {
        box {
            <-1,-1,-0.1>, <1,1,0.1>
            pigment { wood }
            finish { ambient 5.0 diffuse 0 specular 0 phong 0 reflection 0 }
            scale 0.5
        }
    }
    translate <1,0,0>
}

plane
{
    <0, 1, 0>, -1
    texture
    {
        pigment { color rgb <0.5, 0.5, 0.55> }
        finish { specular 1.0 }
    }
}

See attachments for the output. As can be seen, POV-Ray 3.7 does translate the shape of the looks_like object along with the light source, but fails to translate the textures.

Hopefully platform specific, other ports are welcome to check their scaling code.

Using POV-Ray 3.7 RC6 64bit for Windows
I have problems in the POV-Ray editor with ‘backspace’:

When using backspace at start of line
it does not only kill the return/line feed, but also
everything of the line what’s beneath the upper line.

Sample: (here ‘|’ is used for the current cursor position!)

//--------------------------------------
texture { pigment{ Red }
|         normal { bumps 0.5 scale 0.1 }
//--------------------------------------

hitting backspace results in:

//--------------------------------------
texture { pigment{ Red }| 0.5 scale 0.1 }
//--------------------------------------

and not as expected:

//--------------------------------------
texture { pigment{ Red }|         normal { bumps 0.5 scale 0.1 }
//--------------------------------------

With 3.6.2 and with RC3 (latest old beta I found on my computers)
this was no problem!

I already reported this on 17-Sept-2012 at
http://news.povray.org/povray.beta-test/thread/%3C5056f452%241%40news.povray.org%3E/

Recently, I have been rendering an animation with POV-Ray 3.7 RC 6 using radiosity, photons and backside illumination. Many frames contained artefacts like in the attached image file. Trying to eliminate those artefacts I observed the following:

• Rendering the same frame several times did not reproduce the artefacts or reproduced them differently. I.e., when I rendered a second (third, fourth, ...) time with +SF100 +EF100, the black space in the image was somewhere else or in some cases disappeared.
• With radiosity turned off, no such artefacts have happened since, even in the scenes where they happened with radiosity turned on.
• Turning off photons with radiosity still turned on did not remove the artefacts.
• Rendering with one thread on one CPU core instead of two threads on two cores did not change anything except the rendering time.
• Changing the radiosity settings I have not tried thoroughly, but at least raising or lowering count or error_bound does not seem to have any effect on this.

While POV-Ray was rendering, no other memory-intensive or CPU-intensive programs were running and POV-Ray itself did not report any error (just the usual warnings that some of the used features could change in future versions etc.). Render priotity was set to “high”.

When aborting a render when there are unfinished blocks among finished ones, under certain conditions some of those blocks are skipped when continuing the render later.

.../scenes/objects/fractal2.pov

in global_settings  "max_trace" should be "max_trace_level"

.../scenes/advanced/diffuse_back.pov

in global_settings  assumed_gamma statement should not be followed by a semicolon

.../scenes/advanced/blocks/stackernight.pov

in global_settings  "assummed_gamma" should be spelled "assumed_gamma"

.../scenes/portfolio/*.pov

in all files other than _empty.pov the parse stops at the lines containing "[frame_number-1]" I'm guessing it should be "[frame_number]-1"  

Hi,

when I’m trying to render a scene on my MacBook Air with the following .ini-settings, I get a failed assertion and the program halts.

Here are the .ini-Settings:

Width=640
Height=480

Test_Abort=Off
Continue_Trace=On
Pause_When_Done=Off
Verbose=On
Draw_Vistas=Off
Sampling_Method=1
Quality=9
Jitter=Off
Display=Off
Buffer_Output=Off
Debug_File=false

Final_Frame=10

This is the failed assertion:

Assertion failed: 1), function SetRGBFTValue, file image/image.cpp, l

Oddly, if I change width and height to something very small like 320×200, it works.

This is the complete stack trace:

3.6x only bug with easy/known fix. Error message: “Identifier expected, incomplete function call or spline call found instead.” caused by token counter variable using the wrong special value. The symptom occurs when using a lot of splines. See this thread for details.

(I am using a self-compiled special build because I use a lot of splines in 3.6 but would rather use an official 3.6)

The parser is missing extra period characters when it parses a float as a vector component.

#local sample = <0.0.0.1,0,0>;

The following scene, showing an almost cylindrical cone floating above a plane, renders fine in POV 3.6.2, but is obviously broken in 3.7.0.beta.34:

camera {
  right     x
  up        y*image_height/image_width
  location  <80,50,40>
  look_at   <0,0,0>
}

light_source { <500,500,500> color rgb 1 }

cone {
  <0,0,30>, 11.303000, <0,0,-30>, 11.302999
  texture { pigment { color rgb 1 } }
}

plane { y, -20 texture { pigment { color rgb 0.3 } } }

The error occurs even with the -MB option, indicating that the problem has nothing to do with bounding, but is in the cone intersection testing code.

Reported by cshake + pov @ gmail . com in p.beta-test, 14th december 2009

I wrote a simple script to convert fractint color maps to povray color_maps so I could use ApoMap to make nice fractal colors for pov, but I ran into
“Parse Error: Blend_Map too long.” The map has entries from 0/255 up to 255/255 (inclusive). I looked up the documentation which says that color_maps can have from 2 to 256 entries, and this is exactly 256 entries.
I’m posting this in beta-test because I assume that the documentation is correct for v3.6, and that a previous version can handle 256 entries.

FileBackedPixelContainer uses a FILE* to manage the backing store and under Linux/Unix defines fseek64 to be a kind of incantation of lseek64.

Since fseek64 and fseek64 have return values that are logical opposites this causes an exception to be thrown.

Moreover since the buffer size on a FILE is quite a bit smaller than a line of pixels (in terms of bytes), mostly what’s being done in this function is a lot of sloshing of bytes that don’t do much... which is to say that the intended caching mechanism is getting a very low hit rate now that povray is working in 32×32 pixel per-thread chunks.

The cache miss problem and the volume of bytes read/written grows exponentially as the size of the image grows.

Attached is a replacement function that seems to be working well and should produce a performance increase even under Windows. I originally went with simply fixing the fseek/lseek problem but saw a 10% decrease in render time on 2048×1024-sized images when I made the cache target smaller.

parser fails to report when an illegal map_type is used. For example map_type 10 and map_type 100 doesn’t produce an error

Reflective texture maps can cause a stack overflow crash.

sphere{0,1
  texture{
   bozo
   texture_map{
    [0 pigment{rgb 0}]
    [1 pigment{rgb 0} finish{reflection 1}]
   }
  }
}

Trace level is not handled properly with blobs using per-component reflective or refractive textures, leading to lockups. Stepping through the code, it seems that POV-Ray fails to properly mark the blob object as increasing the trace level.

(Until this bug is fixed, the issue can be worked around in most cases by assigning a reflective texture to the blob as a whole.)

The #switch directive isn’t parsing correctly. In the following construct NO warning or error is generated:

#switch (RF)

case (0)
	rotate z*355
#break
case (144)
	rotate z*7.5
#break
case (216)
	rotate z*5
#break

#end

RF is a variable passed to the macro in which this construct resides. The first ‘case’ action IS executed, but none of the others are on successive calls to the macro. If I properly add ‘#’ to the second case the 1st and 2nd condition are executed but not the last. If ‘#’ is REMOVED from any of the break directives an error is generated and parsing halts.

There is a confirmed bug when writing jpg file format with the current linux build (beta39). when specifying +fj output format the following error occurs:

JPEG parameter struct mismatch: library thinks size is 372, caller
expects 376
JPEG parameter struct mismatch: library thinks size is 372, caller
expects 376
Render failed

this has been confirmed on ubuntu 10.4 and openSuSe 11.2 (assuming 32 bit version) as openSuSe 11.2 64-bit reports no problem

there has been a proposed fix to ~smp/source/base/image/jpeg.cpp that appears to work, however it requires some additional work to make it a platform (linux) and compiler (gcc) specific fix.

povray +Imesh_camera.pov +Omesh_camera.png +FN +W800 +H600 produces a “Failed to parse command-line option” error. when I rename my pov source file to ess_mesh_camera.pov it runs fine. seems to be pointing to a clash with the +im option. i also had another file that renaming it got me going.

#macro A()
    #local f = function { x }
#end

#local f = 1;
A()

This gives:

File 'bug.pov' line 2: Parse Error: Attempted to redefine float identifier as
 function identifier.

The problem is that this makes using functions in library macros difficult. Basically, they must have a globally unique name that’s not used in any of the macros or files that call the macros. #undef doesn’t really help, because it destroys the identifier in the calling scope.

For example, one of the macros in the standard include files names a function “fn”, so this doesn’t work:

#include "transforms.inc"

#local fn = 42; // fnord?
#local fn_pos = vtransform(x, transform { rotate 30*y } );

The reason for this restriction is explained in Parse_RValue in source/backend/parser/parse.cpp:

    // Do NOT allow to redefine functions! [trf]
    //   #declare foo = function(x) { x }
    //   #declare foo = function(x) { foo(x) } // Error!
    // Reason: Code like this would be unreadable but possible. Is it
    // a recursive function or not? - It is not recursive because the
    // foo in the second line refers to the first function, which is
    // not logical. Further, recursion is not supported in POV-Ray 3.5
    // anyway. However, allowing such code now would cause problems
    // implementing recursive functions after POV-Ray 3.5!

In this case the restriction is applied too broadly: it should be safe to redefine anything other than a function to a function and still avoid it looking like recursion. In fact, there’s a restriction in Parse_Declare specifically to prevent redefining functions.

I tried to use 3.7 RC3. This was my first time with 3.7.

I got source, configured and compiled it and installed into Debian with checkinstall. And then I tried to use it. First run was with -benchmark (it took about 9 minutes, ok). Then I tried very simple scene:

rekcahx@oah:~/pov$ povray +Iaa.pov
povray: This is a RELEASE CANDIDATE version of POV-Ray. General distribution is discouraged.
Failed to parse command-line option

I tried to debug with strace:

rekcahx@oah:~/pov$ strace -o debug.strace povray +Iaa.pov
povray: This is a RELEASE CANDIDATE version of POV-Ray. General distribution is discouraged.
Persistence of Vision™ Ray Tracer Version 3.7.0.RC3 (g++ 4.6.1 @

Thin tori exhibit artifacts in 3.7.0 RC3 when the camera is placed inside the torus close to its “center plane”, as can be demonstrated with the following scene:

camera {
  location  <0.0, 0.0, -0.5>
  direction 1.5*z
  right     x*image_width/image_height
  look_at   <0.0, 0.0,  0.0>
  angle 1
}

light_source { <-30, 30, -30> color rgb 1 }

torus {
  1, 0.001
  texture { pigment { color red 1 } }
}

A pigment statement not wrapped in a texture statement does not properly override a pigment previously defined for the object. In the following SDL code:

  #declare PLANE = plane { y,0
    texture {
      pigment { checker color rgb 1 color rgb 0 scale 0.1 }
  } }
  object { PLANE
    pigment { checker color red 1 color blue 1 scale 1.0 }
  }

the scaling of the pigment previously specified for the PLANE object is retained for the new pigment. Compare:

  #declare PLANE = plane { y,0
    texture {
      pigment { checker color rgb 1 color rgb 0 scale 0.1 }
  } }
  object { PLANE
    texture {
      pigment { checker color red 1 color blue 1 scale 1.0 }
  } }

which behaves as expected.

The issue has been around at least since POV-Ray 3.6.2.

In gif.cpp (source/base/image), circa line 150:

			case ',': /* Start of image object. Get description. */
				for (int i = 0; i < 9; i++)
				{
					if ((data = file->Read_Byte()) == EOF)
						throw POV_EXCEPTION(kFileDataErr, "Unexpected EOF reading GIF file");
					buffer[i] = (unsigned char) data;
				}

				/* Check "interlaced" bit. */
				if ((buffer[9] & 0x40) != 0)
					throw POV_EXCEPTION(kFileDataErr, "Interlacing in GIF image unsupported");

The loop reads the 9 bytes of the Image Block, but is testing the tenth byte for interlacing.

Reference for image format: http://www.onicos.com/staff/iz/formats/gif.html#ib

When the gif is generated by Gimp, the Image block is preceded by the comment block which default to “Created with GIMP”... the comment is read in the buffer, and the “i” will be in buffer[9], any letter after @ will indeed block povray.

This bug was not present in 3.1g nor in 3.6.1 (due to different source to handle gif).

If not created by Gimp, or with shorter comment, the content of buffer[9] is more random, yet it might trigger the bug depending on the previous blocks and their handling.
