206 | Other | Possible Bug | 3.70 RC3 | Very Low | Low | "Cannot open file" error when text output files specifi... | Tracked on GitHub | |
3.71 release |
Task Description
I created an INI file which specifies the Input_File_Name, Output_File_Name, and also the Render_File and the remaining four text outputs as double-quoted absolute paths on my disk. When I run the render, I get the following output:
Preset INI file is ‘C:\USERS\TPREAL\DOCUMENTS\POV-RAY\V3.7\INI\QUICKRES.INI’, section is ‘[512×384, No AA]’. Preset source file is ‘D:\Ruby\POV-Rb\ini\20110521_004037_Noix.ini’. Rendering with 2 threads. - Cannot open file. Render failed - CPU time used: kernel 0.06 seconds, user 0.02 seconds, total 0.08 seconds. Elapsed time 0.52 seconds.
And the render does not start. The five text output files are not even created, and where the output image should be, there is a file with extension pov-state. The render works as it should only when I remove all five lines defining the five text output files. The paths I specify for the files are correct (paths exist and files do not, no white-spaces or anything), read/write restrictions are disabled in POV-Ray. This used to work in 3.6 and does not work now in 3.7 RC3. The error happens no matter if I run the render using GUI or command line.
(Also please note that the error message is really not useful here, it does not say which file it failed to open, and not even if it was an attempt to open for read or for write.)
I’d be really glad if you could correct this as it’s a critical functionality for me. I’m generating the POV-Ray code automatically and I need to parse the text output automatically to return the status to the generator.

118 | Light source | Feature Request | 3.70 beta 37a | Very Low | Low | More efficient handling of fading lights | Tracked on GitHub | |
3.71 release |
Task Description
Currently, fading light sources are used for lighting and shadow calculations even when so far away as to no longer have any effect on the outcome. The proposed solution is to add a new keyword fade_cutoff_distance which tells povray to ignore the light source when alluminating a point at larger distance.
A sample implementation is provided in the attached files. These changes are still based on beta 34 as sources for the current beta are not yet available, and starting to merge changes to beta 35 only at this time didn’t seem worth the effort. Also, please disregard, changes in the CVS header comments (I also use CVS locally for managing source files).
Further considerations regarding this feature:
- For special effects this feature can also be used if the light source does not actually use fading. On the other hand, cutting the light at some distances can be considered an extreme form of fading which may justify the keyword name anyhow.
- Depending on how FS#46 is implemented, the test for cutoff may then be needed at another location as well.
- The default value currently is 0 (or *no* cutoff distance). For #version 3.7 of higher, the default could be chosen automatically based on the light source intensity and adc_bailout, although it may then need to be overriden by the user for extreme pigments.

304 | Parser/SDL | Definite Bug | 3.70 RC7 | Very Low | Low | #for-loop may fail to perform last iteration | Closed | |
3.70 release |
Task Description
Using an end value of 1048576 or larger in a #for loop will cause the last iteration to be skipped, as can be demonstrated by the following code:
#declare N = 2000000; #debug concat(”N = “,str(N, 0,50),”\n”) #debug concat(”N-5 = “,str(N-5,0,50),”\n\n”) #for (I, N-5, N, 1)
#debug concat("I = ",str(I,0,50),"\n")
#end
(The limit was observed with a Win64 build; other builds may exhibit other limits or might even work fine, depending on the floating point engine used.)
As this limit is still far below the numeric precision limit, and a corresponding #while loop works fine with much higher values, this must be considered a bug rather than an inevitable limitation.
The bug can be tracked down to a faulty condition in tokenize.cpp, Parser::Parse_Directive(), CASE(END_TOKEN), case FOR_COND:
if ( ((Step > 0) && (*CurrentPtr >= End + EPSILON)) ||
((Step < 0) && (*CurrentPtr <= End - EPSILON)) )
which should instead be:
if ( ((Step > 0) && (*CurrentPtr > End + EPSILON)) ||
((Step < 0) && (*CurrentPtr < End - EPSILON)) )

Numbers 2, 3, 4, 8, 9, 10, 11, 12, 13 & 14 are related to the handling
of session (and occur once or twice only, excepted #8, four times).
Number 1 is about isosurface (adjusting gradient at isosurf.cpp:1099 vs
1098 (testing its value), and copying the isosurface) (IMHO, rendering
threads updating the object... not the best move without some
atomic/protection (and not sure a DBL is/can be atomic)) (occurs 2505
times).
Number 5, 6 and 7 are about splines
* sp->Cache_Type & Cache_Point, splines.cpp :803 vs :814/815 (2024 times)
* sp->Cache_Valid, :805 vs :813 vs :904 (1770 times)
* sp->Cache_Data, :807 vs :903 (5025 times)
Only my 0.02¢ (yes, very cheap), but it seems to confirm
For test code see attached files or SplineThreadSafety.pov attachment to p.bugreports and images were posted to p.b.images.
Issue shows up any time more than one thread is used. Use of AA tends to hide the problem so do not use it if using the output image for testing.

Task Description
The following scene has four spheres with different pigment color & filter settings:
- Left: filter 1 - Right: filter 0
- Top: red 0.0 green 0.5 blue 1.0 - Bottom: red 0.00 green 0.05 blue 0.10 (10% of the above)
Background is set to black, so that we only see the diffuse component of the object’s effective color.
Theoretically, both left spheres should be invisible, as they are fully transmissive (with a filtering effect), but apparently with a high filter setting, reducing an object’s pigment color actually increases the object’s effective diffuse color.

Task Description
When running make on Linux, the backend source files (and possibly others?) are apparently compiled twice: first from the .../source/backend/ directory, and another time from the .../source/ directory. As an example, here are the corresponding lines for sphsweep.cpp:

3.70 release |
Task Description
Keyword Completion does not work for several names. I miss it for animation related names like frame_number or final_frame.
Typing “fram{TAB}” just inserts a TAB character after “fram” instead of completing it to frame_number.
Independently of that bug, typing {TAB} repeatedly does not cycle through possible names: “fr{TAB}” gives “frequency” and “fresnel” and that’s all.
In version 3.6 it worked well.
My system is Windows 7 64bit and PovRay is 3.7.0.RC3.msvc9.win64

170 | Refactoring/Cleanup | Unimp. Feature/TODO | 3.70 beta 39 | Very Low | Low | Reduce memory footprint of output image buffer | Closed | |
3.70 release |
Task Description
Currently, output image is buffered using POV-Ray’s RGBFT color model and floating point values, leading to a memory consumption of 20 bit per pixel. This is an unproportionally large memory footprint, given that the only further processing performed on the buffered data is conversion of the data to the desired output file format, which will typically use only 3 bytes per pixel (at most 12 bit per pixel).
The situation can be improved by choosing the output image buffer container based on the desired output file format and parameters. To this end, the following code changes should be made:
Bundle image file format handler code into classes (typically one per file format)
Include a method to determine the best data container type for the image buffer
Instantiate the desired image file format handler object prior to rendering, querying the handler object for an image buffer
In addition to picking a suitable image data container from the already existing palette, careful design might also allow to use custom containers to directly pass the data to a library (in case the library provides its own buffering anyway), or write it directly to the output file (e.g. when writing image data to stdout). To make this compatible with multithreaded rendering, the following changes would have to be made:
Add code to detect when a row of SMP blocks has been finished, and call a certain method on the image handler object
Design the custom containers in such a way that they can buffer any number of unfinished SMP block rows as needed

141 | Documentation | Compatibility Issue | 3.70 beta 37a | Very Low | Low | Document changed behavior processing INI files | Closed | |
3.70 release |
Task Description
The documentation assumes that INI files (as well as the command line!) are parsed and processed instantly. This no longer holds true for POV-Ray 3.7, where parsing INI files (and the command line) and processing it are separate operations that occur at different times. As such, one consequence is that INI file options only take effect after reading the whole INI file, and possibly later.
As such, documentation statements such as <http://www.povray.org/documentation/view/3.6.1/222/> “Note: that these options take effect immediately when specified. Obviously any error or warning messages that might occur before the option is read will not be affected.”
Are no longer correct. It needs to be explained that options only take effect after the INI file has been read. An error in the INi file causes other options _not_ to take effect because reading of the INi file is aborted prematurely.

3.70 release |
Task Description
Beta 32, compiled from source on Linux/Ubuntu, amd64.
The random “window display lock” is back. (as the previous “solution” was to get no window display usable, that’s not so bad).
What is it: sometime, when the rendering window is activated, povray just draw the frame of the window, paint it black, does not display anything else but seems to perform the rendering in separate threads. Whenever the mouse move over the frame of the window, it unlock the updating process and big parts of the rendered image pop up.
What it is not fine: if you do not move the mouse over the window, povray will just stall. This is more a problem for animation rendering, as getting the display might be a wanted bonus to monitor the rendering images, and you just fall into that lock: your expected night rendering could very well be suspended on the first frame. Moreover, the “move the mouse over” works only for local display. In previous beta (not yet checked with 32), with a remote display, there was no way to unlock povray.

Logically, I cannot see a reason for this to be so.

334 | Texture/Material/Finish | Feature Request | 3.70 release | Very Low | Low | HLS colors | Tracked on GitHub | |
|
Task Description
It would be nice to be able to specify colors in HLS as well as RGB.
Currently, you can use a macor to convert individual colors. But this does not work in color_maps where you want smooth gradations/interpolations between two or several colors.

Task Description
When you press alt+b or access the “about” dialog in the Help menu it displays some text including software version number and list of contributors.
It would be nice to be able to select and copy this text using this mouse. Sometimes in the newsgroup I have to tell people what version of POVray I am using, and typing the version number can be a pain.

332 | User interface | Feature Request | 3.70 release | Very Low | Low | Progress animation in taskbar tabs | Closed | |
|
Task Description
On Windows 7 and newer operating systems, some programs are able to display their progress in the taskbar buttons.
Here is an example of Chrome downloading something and showing the progress in the taskbar:
http://www.winbeta.org/sites/default/files/news/oldfashinoned.jpg
Here is an example with Paint.NET instead:
http://www.getpaint.net/images/pdn351_superbarProgress.png
I think this feature would use fewer CPU resources than a) minimizing/maximizing the whole application window each time you want to check progress, or b) hovering the mouse over the taskbar button to show the thumbnails.

331 | Geometric Primitives | Definite Bug | 3.70 release | Very Low | Medium | Intersection causes quadric to disappear | Closed | |

Task Description
The following paraboloid renders correctly:
intersection
{ quadric { <1, 0, 1>, <0, 0, 0>, <0, 1, 0>, -1 }
cylinder { 0, y, 1 }
}
However, when I extend the clipping cylinder downward:
intersection
{ quadric { <1, 0, 1>, <0, 0, 0>, <0, 1, 0>, -1 }
cylinder { -y, y, 1 }
}
the object disappears completely in POV-Ray 3.7 and 3.7.1. In POV-Ray 3.6.1, it renders as expected.

On the right side, there should have been a cylinder capped with a paraboloid. A thread has been started in povray.bugreports. Jerome has started to look at it.

Any option that gets a filename as parameter will fail if it contains ‘=’.
It is a regression, as it worked fine with 3.6.

326 | Other | Definite Bug | 3.70 release | Very Low | Low | restricted setting ignored in 3.7 | Tracked on GitHub | |
|
Task Description
Due to a typo in the conf file parser (introduced, I think, in refactoring after 3.6), the restricted setting is ignored, and access checks aren’t performed.
Fixing this reveals some other issues:
%INSTALLDIR%/../../etc is incompletely canonicalized to /usr/local/share/../etc , not /usr/local/etc
read+write paths are added to the read list only, so writing is impossible
See attached patch.
Relatedly, I think it would be nice to add a new replacement token %CONFDIR% instead of %INSTALLDIR%/../../etc .
Also, there’s a realpath function that could simplify path handling, though I’m not sure if it’s available on all platforms.

325 | Subsurface Scattering | Possible Bug | 3.70 release | Very Low | Medium | SSLT Glow issue with radiosity | Closed | |

Task Description
Hi,
I think I may have found a bug in the subsurface/radiosity features of Povray 3.7 attached image showing the issue and sample files required to reproduce. The original files (on povray forum images thread) had different radiosity settings but these ones show the problem and only take a few seconds to render the image without AA so probably better for bug fixing/testing etc.
Thanks

324 | Geometric Primitives | Definite Bug | 3.70 release | Very Low | High | 3.7 mesh2 rendering artifact, regression from 3.6 | Tracked on GitHub | |
|
Task Description
Povray 3.7 has rendering artifact in meshes with polygons that meet at shallow angles. Please see the attached file.
The part of concern is the mesh2, which produces the partly-transparent faces of a shallow pyramid. The file result-3_6.png shows the output of povray-3.6, and the file result-3_7.png shows the output of povray-3.7. In 3.7, you can see a thin light-colored margin all around the base of the pyramid, especially thick under the top cylinder. In 3.6, this artifact is absent. For comparison purposes, I have inserted a “#version 3.6;” directive at the top of the file so that the output images are as close to each other as possible. However, the artifact is still present in 3.7 without this directive.
The attached scene file is only a small part of a much larger scene, where this artifact shows up in numerous very obvious places, where it doesn’t in 3.6. I have hunted in the documentation and online for ways to solve this problem, but haven’t found anything. Because of this, I am forced to stay with 3.6 for production use, which is quite unfortunate since I’d like to take advantage of the new features of 3.7.

320 | Animation | Definite Bug | 3.70 release | Very Low | High | Failed Assertion in image/image.cpp | Closed | |
|
Task Description
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:

Task Description
Reported in p.beta-test by James Dietrich (2013-12-12)
when the display window must be scaled (because one or both dimensions are larger than the actual screen), the ratio of scale might be too large in some occasion, performing a memory corruption in two places and usually crashing povray.
How to reproduce, with a 1920×1080 display (or 1920×1200):

314 | Comments/Typos | Definite Bug | 3.70 release | Very Low | High | reading Gif is bugged in 3.7 | Closed | |
|
Task Description
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.

308 | Geometric Primitives | Definite Bug | 3.70 RC7 | Very Low | Medium | Heightfield computation from color (not palette) red/gr ... | Closed | |
|
Task Description
Due to a recent thread in povray.general (7th September 2013), I dive into the code of height field creation.
There is 2 TODO in source/backend/support/imageutil.cpp, for image_height_at() (circa line 512)
The first one is about using the index of palette-image: As far as *257 would indeed perform a better job to cover the full range than *256, it would break backward compatibility with previous versions of povray (3.6 included) which only promoted the index as the Most significant byte, keeping the least one at 0.
But on the second one, the new formula is plain wrong: (r*255+g)*255 should be (r*256+g)*255. In previous versions, r*255 was the Most significant byte, and g*255 was the least one. Ergo, the value was r*255*256 + g*255, which can and should be only factored as (r*256+g)*255;
I know it is damn late in the release schedule, but can that be either be fixed before final official delivery or a memo added to the release note that it would be fixed later and backward-bug will not be maintained for that specific point (using rgb-8 or less bit per channel-image for height field)
(it was not bugged in 3.6.1 nor before, it’s just that tiny little bit of 3.7 that would should that bug)
If you look carefully at the attached pictures (povray +I... +H700 +W700 +A0.01) of scene and scene36, there is a significant difference at the top. With 3.6, it matched exactly (hence the noise on the top pixels row) the view. With 3.7, it cannot reach the top and leave a white area (another difference is the slope on the side are also a bit more lower with 3.7, easier to spot when alternating the display of both pictures)
If you want to regenerate hf.png, it was rendered with povray 3.7RC7, +W400 +H400 +A0.01 +Ihf.pov
The white line at the bottom is expected, as the minimal value of the height field is “full green”

307 | Image format | Definite Bug | 3.70 RC7 | Very Low | Low | netpbm, ppm, read bug where first data byte CR char | Closed | |
|
Task Description
I’ve recently been working with the netpbm ppm format and I have hit what I believe to be a bug in the way ppm files are read – very likely a bug in all netpbm formats. I am aware of the long standing povray issue with the netpbm file formats header where the height and width need to be on the same line as the magic number though that is not a requirement of the official format. This bug is different.
Namely in working with a larger number of ppm files I hit cases where a few would fail with the message : “Possible Parse Error: Unexpected EOF in PPM file” though the ppm files are fine. What is happening is that the first byte of data after the line feed (LF) (Ubuntu linux 12.04) happens to have a carriage return (CR) value.
The code which is set up to interpret the netpbm headers is reading a lines with “file→getline (line, 1024);” and this line reading code is pulling in the first byte of data with the CR value as part of the line. When the read by binary data, 8 or 16 bits at a time, starts, the povray read code is offset into the data by one byte too many.
The result from 10,000 meters, if input values were completely random file to file, would be netpbm read fails for size that make no sense in 1/256 files. In practice & depending on data some might never see fails while an unfortunate few might almost always fail.
I’d make some argument any CR following a LF character should not be pulled in as part of the line read even on windows/dos systems where CRLF is the usual line termination order. I think though the real fix is better netpbm header reading code which more strictly breaks apart the header on the first whitespace character doing the last depth break, aware of the file size, so it can decide what portion of any valid sequence of whitespce characters after the decimal depth value is data and not whitespace.
The attached tarball when unpacked has both a passing and failing case. To run “povray fails.pov” or “povray works.pov”. The only difference between the two ppm files if the fails.ppm data is all 0x0D while works.ppm data bytes are all 0x0C. The image rendered is meaningless.
Thanks for your time. Bill P.

305 | Geometric Primitives | Feature Request | 3.70 RC7 | Very Low | Low | remove maximum component limit for blobs | Closed | |
|
Task Description
Blobs are currently limited to 1,000,000 components (with each cylindrical component counting as three: one cylinder + two end hemispheres); this limit may have served a historic purpose, but is now entirely arbitrary: The remaining code is limited only by the available RAM and the numeric limits of the int data type. The arbitrary maximum components limit per blob should therefore be removed.
Aside from unnecessarily limiting the power of the blob component, another drawback of the current test is that it is only performed after parsing of all the blob’s components, potentially hours after the limit had actually been reached.

302 | Other | Possible Bug | 3.70 RC7 | Very Low | Low | confusing error message when .ini file cannot be parsed | Tracked on GitHub | |
|
Task Description
When a command-line parameter in an .ini file cannot be parsed (such as “+a.3”), POV-Ray reports a “Problem with setting”, quoting the command line, rather than indicating that the problem occurred in an .ini file. This leads the user to think that the problem is with the command line itself, unnecessarily confusing him.
