295 | User interface | Definite Bug | 3.70 RC7 | Very Low | Low | Minor GUI Bugs | Tracked on GitHub | |
|
Task Description
Here are two low-priority bugs in POV-Ray’s GUI, observed by me under Windows XP, which should be easy to fix I think:
In the “Insert” menu, there are sub-menus (e.g. “Radiosity and Photons”) in which there are menu seperators at the end of the popped-up menu bar.
The progress bar in the top-right corner of the editor window seems to be too large for the window (203px) and therefore clipped. As a result, progress seems to be 100% when it is not yet, e.g. at 90% progress. (Have not measured exactly.)
Both bugs are not severe at all, but it would be nice if they could be fixed. By the way, a second progress bar could be added to visualize the number of frames already rendered in an animation.

It appears as a side effect of investigation of #294: the code in isosurf.cpp, inside bool IsoSurface::Function_Find_Root_R(ISO_ThreadData& itd, const ISO_Pair* EP1, const ISO_Pair* EP2, DBL dt, DBL t21, DBL len, DBL& maxg)
if(gradient < temp)
gradient = temp;
is not thread-safe (The code is used at render time, there is a data race between < and = operation, as gradient is stored in the global object and accessed in write mode by the cited code)
It is only important if the gradient is initially undervaluated (otherwise, all is fine, no write-access)

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.

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.

3.70 RC4 |
Task Description
Adjusting the brightness of an image-mapped sky sphere, although not an uncommon task especially when using HDR light probes, currently is cumbersome at best, as it is not possible to specify a “finish { ambient ... }” statement.
To simplify tuning a sky sphere’s brightness, I suggest introducing a “brightness FLOAT” modifier (defaulting to 1.0) to either the sky_sphere block or (as a more versatile solution) the image_map statement.

10 | Parser/SDL | Feature Request | 3.70 beta 32 | Very Low | Medium | Add support for specifying input images' gamma pre-corr ... | Closed | |
3.70 beta 40 |
Task Description
Input image files may have been created with gamma pre-correction for some specific target gamma, which may vary from image to image. Some file formats like PNG or HDR support embedding gamma pre-correction information in the image file, but this information may be missing or faulty, and some formats don’t support it at all. Additionally, it may be desirable to tamper with an input image’s gamma for artistic reasons.
Therefore, I suggest adding a means to explicitly specify input images’ originally intended target gamma on a per-image basis, like:
image_map { jpeg "MyImage.jpg" assumed_gamma 1.8 }

Task Description
In POV-Ray 3.6 (including 3.62), checker and cells patterns are off by 0.001 (1e-3) units, as can be demonstrated with this scene:
camera {

box { < 1, 1,0>, <0,0,1> pigment { checker color rgb 1 color rgb 0 scale 0.2 translate < 0.5, 0.5,0> } finish { ambient 1 diffuse 0 } }
box { < 1,-1,0>, <0,0,1> pigment { checker color rgb 1 color rgb 0 scale 200.0 translate < 0.5,-0.5,0> } finish { ambient 1 diffuse 0 } }
box { <-1, 1,0>, <0,0,1> pigment { checker color rgb 1 color rgb 0 scale 200.0 translate <-0.5, 0.5,0> } finish { ambient 1 diffuse 0 } }
The same can be demonstrated for the cells pattern.

76 | Other | Feature Request | 3.6 | Very Low | Medium | Povray returns incorrect exit code when aborting render | Closed | |
3.70 release |
Task Description
If you abort a render with ^C, Povray exits with a ‘success’ error code.
To test:
povray scene.ini
(^C to abort it)
echo $?
Right now 0 is returned (’success’). A non-zero value should be returned (’failure’).
This is particularly important for scripting, where command lines like:
povray scene.ini && halt
...can be used. I only want the halt to be executed if the scene renders successfully. If I change my mind and ^C it, I don’t want the machine to shut down!

|
84 | Parser/SDL | Feature Request | Not applicable | Defer | Very Low | A for-loop construct | Closed | |
3.70 beta 37 |
Task Description
Many people clearly miss a simple for-loop construct in povray. It is indeed true that probably at least 99% of #while loops out there have the form of a simple for-loop. It’s much rarer to have to use more exotic forms of looping supported by the #while mechanism. Thus it would make sense if a #for construct would be added which would make writing such loops much easier and convenient.
The only remaining question would be the syntax.
IMO the for-loop construct should implicitly declare a local variable of a specified name, automatically increment it during the loop, and then undefine it after the loop ends. It could perhaps be something along the lines of:
#for(<identifier name>, <initial value>, <final value> [, <step>])
<loop body>
#end
Example:
#for(Counter, 1, 10) // 'Counter' gets values 1, 2, 3, ..., 10
#debug concat(str(Counter, 0, 0), "\n")
#end
#for(Counter, 1, 10, 3) // 'Counter' gets values 1, 4, 7, 10
#debug concat(str(Counter, 0, 0), "\n")
#end
I think this syntax ought to be relatively easy to implement (compared to more “traditional” syntaxes, such as something like “for Counter = 1 to 10” or the C syntax, which would be a lot more complicated).
Of course this raises a couple of questions:
1) What happens if ‘Counter’ was already declared as an identifier? One of three possibilities comes to mind:
2) Should the user be able to modify the counter variable from inside the body of the loop? Something like this comes to mind as viable:
// Prints the values 1, 2, 3, 9 and 10
#for(Counter, 1, 10)
#debug concat(str(Counter, 0, 0), "\n")
#if(Counter = 3) #local Counter = 8; #end
#end
Alternatively the counter variable could be read-only.
Additionally, it could be nice if #break could be used to immediately jump out of the current loop (either #while or #for).

Task Description
Many programming languages support an indeterminate number of parameters in functions/macros.
JavaScript for instance supports an “arguments” object.
Lua for instance supports the “args” object.
I would like to see that added to POV as well.
Here’s an JavaScript example:
function ArgTest(a, b){
var i, s = "The ArgTest function expected ";
var numargs = arguments.length; //Get number of arguments passed.
var expargs = ArgTest.length; //Get number of arguments expected.
if (expargs < 2)
s += expargs + " argument. ";
else
s += expargs + " arguments. ";
if (numargs < 2)
s += numargs + " was passed.";
else
s += numargs + " were passed.";
s += "\n\n"
for (i =0 ; i < numargs; i++){ //Get argument contents.
s += " Arg " + i + " = " + arguments[i] + "\n";
}
return(s); //Return list of arguments.

Task Description
Currently, many POV scenes/include files behave differently depending on the basic units used within the scene. Scaling them differently can affect things like ior and media. A master system variable that users can set to configure the scene’s units would be beneficial for sharing and collaboration purposes, so that person A’s glass interior works correctly in person B’s wine glass scene. Just like the #version system variable, it should have a default value but should be possible to explicitly override.

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.

#local temp_camera_1 = camera
{

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.

187 | Frontend | Feature Request | 3.70 beta 41 | Very Low | Low | POV-Ray 3.70 ignores SIGTSTP signal, noisy on SIGWINCH ... | Closed | |
3.70 RC2 |
Task Description
When POV-Ray 3.70 is run on a terminal, on an unix shell, and the user hits ctrl-Z to suspend (stop) POV-Ray, rather than stopping as expected, POV-Ray just reports that it did receive the signal, as if to laugh at the user “I’m not obeying your puny stop attempts”. It
The default action (as happens if the SIGTSTP signal is not trapped) would be much better, and is usually safe also in multithread programs. It takes actual effort to _ignore_ the TSTP signal (namely, to trap that signal), so the current behavior is definitely a dysfeature, probably an oversight by whoever programmed the signal handler.
Also, when the terminal window is resized, POV-Ray needlessly reports that it received a signal number so-and-so (the number of SIGWINCH), adding irrelevant noise to its terminal output. Both signals (SIGTSTP and SIGWINCH) should simply be excluded from the signal trapping mask. I guess there are also other signals that are needlessly captured. It would be better to capture only those signals that an action is needed for.

190 | Photons | Feature Request | 3.70 RC1 | Very Low | Low | photon message reporting | Closed | |
|
Task Description
couple of observations:
if no photons are gathered (hey it happens ... my typo) when attempting to save a photon map the warning message just indicates that it couldn’t save the map, maybe the message could be enhanced to say something like: No photons were gathered so no map information was saved. At first I thought something had changed in my I/O restrictions (I’m writing to an image directory not current or work directory)
when reading a previously saved photon map there is no indication that it was read in other than the end stats showing a small amount of photon time. I don’t recall but didn’t v3.6 indicate that the a previously saved map was being used? Just for the heck of it I moved the map file aside and it did prove to me that it was indeed being input. Some sort of message at the time the file is read in might be helpful.
