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.

143 | Backend | Feature Request | 3.70 beta 37a | Very Low | Low | explicit Output_File_Name for images/animations | Closed | |
|
Task Description
The ability to specify an exact name for output images during animations would be great. As it is, POV-Ray appends a numerical designation to each image (e.g. image001.png, image002.png, etc. Overriding this behavior would allow certain tasks to be accomplished without cluttering the hard drive. For instance, an image could be rendered over and over again. Certain things like cellular automata, ripple tank simulations and feedback fractals could be performed without the resulting long list of images in a given directory.
The command line option could be in the form of +oefile/+Output_File_Name_Exact=file or some such.

150 | Frontend | Compatibility Issue | 3.70 beta 37a | Very Low | Low | Windows file association problems (Win7 only??) | Closed | |
|
Task Description
Windows allows you to associate programs with file extensions using the “Open with” file manager right-click menu extension.
I’m running Windows 7 64bit, and installed the 64 bit versions of 3.6.2 and the beta appropriately.
A couple of problems that I haven’t tested very thoroughly:
1. If you have both POV 3.6.2 and the beta installed at the same time, you can no longer using this dialog change the association to the beta once it has been created for 3.6.2. There’s no error or anything; it just opens the file inside 3.6.2 instead. Maybe because both versions appear as “POV-Ray for Windows” to this dialog? Would adding the version number to the name fix things? Anything I can do on my end of things to resolve this?
2. In POV-Ray 3.6.2, I can use this dialog to open *.inc, *.txt and other files in POV-Ray, but only if POV-Ray isn’t already running. If POV-Ray is already running I get an “Only /EDIT and /RENDER may be passed to previous instance” error. Files with the *.pov extension open properly regardless, without any error. I am unable to test this in the beta at the moment due to the first problem unfortunately. Could someone please test this with the beta and confirm whether the behavior also exists?
3. With the POV-Ray 3.7 beta, entering the following command in the command prompt results in the same error:
"C:\Program Files\POV-Ray for Windows v3.7\bin\pvengine64.exe" "D:\Working\Povray\GearHead\LoadingScreen\btr_maanji.pov"
If I change it to the following it works however:
"C:\Program Files\POV-Ray for Windows v3.7\bin\pvengine64.exe" /EDIT "D:\Working\Povray\GearHead\LoadingScreen\btr_maanji.pov"
Is this error/behavior really necessary? Would it be OK to instead change the behavior when the /EDIT flag is omitted in the command-line such that the file is opened in the editor by default, without throwing an error?

152 | Parser/SDL | Feature Request | 3.70 beta 37a | Very Low | Low | Camera in object, union statements | Closed | |
|
Task Description
Currently, cameras placed inside object or union statements will halt the render with an error. Take for instance the following case:
#local temp_camera_1 = camera
{
orthographic
location z*-12
direction z
up y
right x*image_width/image_height
scale 32
}
#local temp_light_1 = light_source
{
0
color rgb 1
translate <-30, 30, -30>
}
#local temp_light_2 = light_source
{
0
color rgb 1
translate <-30, 30, +30>
}
union
{
object {temp_light_1}
object {temp_light_2}
// camera {temp_camera_1} // doesn't work!!!
}
//object {temp_camera_1} // doesn't work!!!
camera {temp_camera_1} // works!!!
Changing this behavior would make it possible to more easily apply transformations to scene objects and the camera at the same time in situations where the scene’s frame of reference is in motion relative to the rest of the scene, for instance in animations.

Installation script (from sources) when run with a classical “sudo make install” would create povray.ini & povray.conf in $HOME/.povray/3.7 (so far so fine) with the owner as root and the permission to readonly for the real user.
Same goes for the owner of the 3.7 directories tree : .povray & .povray/3.7 are created with root owner, despite being in $HOME of the performing user.

145 | Parser/SDL | Feature Request | 3.70 beta 37a | Very Low | Low | Stack trace report on error | Tracked on GitHub | |
|
Task Description
In other languages if you encounter an error you’ll often be presented with a stack trace showing not only the file and line number the error occurred at, but also any calling functions and _their_ calling functions and so on.
Currently, Povray reports the line number of the error as well as the last five or so lines prior to the error. This is usually OK in simple scenes, but breaks down when you start making use of inclusion and macros.
Let’s say you have a macro located in a file that you then include in your scene. Within your scene you call the macro multiple times, passing input to it. However, by accident you pass _invalid_ input to the macro at some point, resulting in an error when parsing. In this case Povray will report the error as belonging to the macro whereas the actual bug exists in the calling code. If the macro is called more than once in your scene it can be difficult to figure out _which_ instance is the one supplying the bad input.
Not sure how much of this is achievable in Povray.

Think this is still a problem. See the attached scene file. Find the WindowFrameSegment declaration for more info. The scene as-is shows the problem (SOME portions of the difference inherit the color of the room) the window opening is scaled larger to show that they AREN’T touching. The problem goes away when (in WindowFrameSegment) the 1st occurrence of the applied texture is commented out and the 2nd occurrence is uncommented, and cutaway_textures is commented out.

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.

I’m sure there are many others, as this is one of those features that has undetermined potential!

151 | Runtime error | Possible Bug | 3.70 beta 37a | Very Low | Low | No way to cancel save while parsing, never ending error... | Tracked on GitHub | |
|
Task Description
On Windows, when I try and save a file while it is being parsed prior to rendering, I get an error, “Failed to save file: The operation completed successfully”, with a single OK button to click. Despite the weird wording, I’m OK with that.
However after clicking OK I get the error, “Failed to save file ‘...’“, with three buttons: Cancel, Try Again, Continue. Not sure what “Continue” means in this context, given that the possibilities would seem to be covered by the other two buttons. Whatever.
Also, sometimes I get a message with only a single “Retry” button. Not sure what the exact message was.
Anyway, the real problem is that, regardless of which button I press, the program continues to spawning the same error message endlessly. Luckily there is a delay between them, but still it would be nice to have at least one of the three buttons *stop* POV-Ray from asking me again.
Also, once the program finishes parsing the file and it becomes possible once again to save the file, it does nothing. I.e. it doesn’t save the file. So what’s the point of the message and all the options? Why not just say, “Unable to save the file, file is parsing” and be done with it?
I think I recall the same behavior in 3.6.2, so it’s nothing new that’s been introduced.

|
Task Description
From post in povray.general (circa 29 september 2010: “Maximum Resolution of Renders?”)
The ultimate goal would be a 41000×41000 image. However each time I have attempted to render that Pov-Ray has crashed on me. Even when using a single, simple test object (a plain white sphere that should use a single pixel). So I think this is running into a program limitation at present.
It won’t be for the faint hearted: a 30500 x 30500 does still produces the bug, but you’d better have 24 GB of true ram to test it. (it’s a render of a few “real” minutes if you do not swap, for any very quick scene (a 305 x 305 in 0.117s moved to 220s for 30500×30500 on my system when corrected))
With core-dumped enable, the issue is pointed in the creator of PixelContainer. The problem is due to the resize() parameter: despite the parameter being a size_t (8 bytes long on 64bits), the computation ( h * w * 5 ) use unsigned int for h & w (and signed int for 5).
As a consequence, the value of resize is computed as a signed int... havoc might happen when the signed bit (#31) is propagated to the #63 to #32 of size_t... vector does not enjoy a negative value for resize (and destroy itself: no iterator on coming soon call! hence the crash when the values in the vector are to be initialised)
30500²: (in hex)
1 15 3C 71 50 floats
4 54 F1 C5 40 bytes
Basic solution: promote the 5 to an unsigned long, forcing the computation to happen on unsigned long, avoiding promotion of silly sign-bit, and keeping the resize’s value as a good number.
aka: resize( w * h * 5) becomes resize ( w * h * 5ul )
This solution has been tested and seems fine (it’s just that in base/image/image.cpp, there is a lot of resize()!). For all resize(), the “ul” must be added. (and that means also that resize( w * h ) must be rewritten as ( w * h * 1ul ). )

Task Description
POV-Ray 3.7-generated JPEG image output files do not conform to the JFIF standard. Most importantly, the files written do not use the standard YCbCr color model (they seem to use plain RGB instead), nor do they have a proper JFIF tag.
As a consequence, some software may be unable to read the generated JPEG files properly. In addition, it seems that POV-Ray mixes up the Red and Blue channels.

3.70 beta 37a |
Task Description
Setting File_Gamma=1.0 produces unexpectedly bright output files for most output file formats, as if File_Gamma was set to 2.2 instead.
The underlying problem is a bug that, when File_Gamma is set to exactly 1.0, causes the encoding gamma function to be undefined, which was not meant to happen in current versions, and instead was reserved for future versions to signal that a file-format-specific default encoding gamma should be used. The image file output handlers already support this, most of them choosing the sRGB transfer function, giving roughly the same output as setting File_Gamma=2.2.
As a preliminary workaround, users may want to set File_Gamma=1.02 (any value smaller than 0.99 or greater than 1.01 should do).

Task Description
POV-Ray 3.7 does not show output options, such as:
Output Options
Image resolution 640 by 480 (rows 1 to 480, columns 1 to 640).
Output file: D:\foo\test.png, 24 bpp PNG
Graphic display......On (gamma: 2.2)
Mosaic preview.......Off
CPU usage histogram..Off
Continued trace......Off
(the above is what 3.6 used to show)

106 | Distribution | Unimp. Feature/TODO | 3.70 beta 37 | Very Low | Low | Update sample scenes and include files for POV-Ray 3.7 ... | Tracked on GitHub | |
|
Task Description
Most sample scenes and include files were designed at times when POV-Ray did not to any proper gamma handling, or still used the inferior 3.6 “assumed_gamma” mechanism.
All the scenes and include files should be reviewed, and updated to fit the new 3.7 gamma model.
The primary task will probably be gamma-adjusting literal color values and ambient parameters; I suggest using macros (which ideally should be defined in an include file) to be set according to the #version statement, so the scene/include file could be kept compatible with older versions.

108 | Parser/SDL | Feature Request | 3.70 beta 37 | Very Low | Low | motion_blur feature similar to Megapov version | Tracked on GitHub | |
Future release |
Task Description
motion_blur which is a simple and effective feature to use in Megapov to simulate motion blur of, e.g. bird wings, propellers or running animals, would be a neat addition to version 3.7 and later.
In Megapov, the feature requires a line of code in the global_settings{} e.g.: motion_blur 10, 2 and a declaration for the moving object. e.g.:
motion_blur {
type 0
object{MyObject material{MyMaterial rotate x*clock*2}}
rotate x*clock*10
}
type represents several types of pre-defined motions.
Thanks,
Thomas

Task Description
Hi,
following scene will not be rendered correctly in 3.7.beta.35a:
http://lib.povray.org/collection/beamtest/cousin%20ricky%201.1/beamtest.html
maybe it is a configuration problem or it is a real bug.

Task Description
The following SDL code
sphere {0, 1 pigment {image_map {png "missing.png"}}
yields “render failed” in 3.7b25 and the position of the error is not highlighted in source code, giving no clue what went wrong. In 3.6 this yields “Parse Error: Cannot open PNG file”.

Future release |
Task Description
Hi,
it would be nice if there exists a test scene (not a benchmark) which has a high coverage of povray source and can be used as correctness validation of povray. It schould be produce an image which can be compared to a golden reference image.
It may be also possible to create a regression test suite which does automatic comparision of the render results.

3.70 beta 37 |
Task Description
In pvengine.cpp (file revision 154), lines 4003-4006 are exact duplicates of lines 3999-4002:
3997 case KEYWORD_LOOKUP_MESSAGE :
3998 hh_aklink.pszKeywords = (LPCSTR) lParam ;
3999 if (strncmp (hh_aklink.pszKeywords, "oooo", 4) == 0)
4000 hh_aklink.pszKeywords = "" ;
4001 if (strncmp (hh_aklink.pszKeywords, "//", 2) == 0)
4002 hh_aklink.pszKeywords = "" ;
4003 if (strncmp (hh_aklink.pszKeywords, "oooo", 4) == 0)
4004 hh_aklink.pszKeywords = "" ;
4005 if (strncmp (hh_aklink.pszKeywords, "//", 2) == 0)
4006 hh_aklink.pszKeywords = "" ;
4007 HtmlHelp (NULL, engineHelpPath, HH_KEYWORD_LOOKUP, (DWORD_PTR) &hh_aklink) ;
4008 return (true) ;
This duplication appears pretty much useless to me - or am I missing something?

88 | Image format | Definite Bug | 3.70 beta 36 | Very Low | Low | File output code does not properly handle negative colo ... | Closed | |
3.70 beta 37 |
Task Description
File output code for virtually all file formats performs gamma correction on unclipped color values, which leads to issues when color values happen to be negative for some reason and gamma does not happen to be an integer value such as 1.0 or 2.0. As a consequence, subsequent steps (clipping and converting to integer) apparently produce compiler-dependent results. Compiled with Microsift or Intel compilers, POV-Ray seems to write zero brightness in such cases, while compiled with g++ 4.4 (and possibly other compilers) it seems to write full brightness instead.
(See thread news://news.povray.org:119/4ba819f6@news.povray.org for examples.)
The proper solution should be to apply gamma correction after clipping.

Task Description
When choosing PPM output with a bit depth other than 8 bits per color channel (e.g. +FP16), POV-Ray messes up the colors (see thread news://news.povray.org:119/4babb48f$1@news.povray.org)

90 | Parser/SDL | Definite Bug | 3.70 beta 36 | Very Low | Very Low | POV-Ray accepts additional patterns after "slope" | Closed | |
3.70 beta 37 |
Task Description
The following code is erroneously accepted by POV-Ray (tested with 3.7.0.beta.36):
pigment{
slope { x }
checker
}
The result is a checker pattern.
Apparently there is an EXIT statement missing in the slope-pattern parsing code in parstxtr.cpp.
