23 | Platform-specific | Compatibility Issue | 3.70 beta 32 | Very Low | Medium | X Window preview might lock | Closed | |
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.

3.70 release |
Task Description
The following files were garbled in changelist #4648 by stripping all line terminators, making the files unusable:
.../scenes/advanced/cats/cattext.inc

Line terminators of these files were already problematic in previous versions of the file, having been CR-only.
The following files changed with #4648 should be reviewed closely as well, as they were previously CR-only, too, and at least some of them exhibit some peculiarities regarding line and/or file terminators:

76 | Other | Feature Request | 3.6 | Very Low | Medium | Povray returns incorrect exit code when aborting render | Closed | |

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!

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.

161 | Image format | Definite Bug | 3.70 beta 38 | Very Low | Medium | error when writing jpg format (linux build) | Closed | |
3.70 release |
Task Description
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.

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

224 | Editor | Compatibility Issue | 3.70 RC3 | Very Low | Low | Keyword Completion does not work for several names | Closed | |
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

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
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.

Numbers 2, 3, 4, 8, 9, 10, 11, 12, 13 & 14 are related to the handling

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_Valid, :805 vs :813 vs :904 (1770 times)
* sp->Cache_Data, :807 vs :903 (5025 times)
Only my 0.02ยข (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.

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)) )

49 | Texture/Material/Finish | Possible Bug | 3.70 beta 32 | Very Low | Low | number_of_waves default value not properly initialized | Closed | |
|
Task Description
When rendering a series of scenes (e.g. animation, or render queue in POV-Ray for Windows), number_of_waves is not properly reset to its default value between scenes, causing the parameter to default to the value set by the previous scene.
For instance, rendering the following scenes from a queue will cause “arches.pov” to be rendered differently the second time:
scenes\textures\finishes\arches.pov
scenes\textures\normals\normavg.pov
scenes\textures\finishes\arches.pov (again!)

57 | Texture/Material/Finish | Definite Bug | 3.70 beta 34 | Very Low | Medium | Compressed TIFF image_map renders all transparent | Closed | |
|
Task Description
The attached TIFF file was created with IC using compression. When used in an image_map, POV-Ray 3.7.0.beta.34 on Windows XP x64 renders the image all transparent, while POV-Ray 3.6.2 renders the file fine. The same effect can be seen with LZW-compressed TIFF files created with Adobe Photoshop 6.0.
Uncompressed TIFF files created with either IC or Photoshop render fine in both versions of POV-Ray.
Stepping through the code of POV-Ray 3.7.0 shows that the same code path is taken regardless of compression, but the libtiff library returns different alpha channel values, indicating a problem in that library. POV-Ray 3.7 still uses libtiff 3.6.1, whereas the POV-Ray 3.6 branch has been updated to libtiff 3.8.2, which according to the change history includes a few alpha-related changes.

The same can be demonstrated for the cells pattern.
POV-Ray 3.7 beta 34 is “clean”.

74 | Texture/Material/Finish | Possible Bug | All | Very Low | Medium | image_maps within pigment_maps are not rendered correct ... | Closed | |
|
Task Description
Hello,
when I use an image_map within a pigment_map (for example only a half of a box gets the image_map), the image_map is not rendered correctly.
For example when I have this box (scene and images are attached)
box {
0, 1
pigment {
gradient z
pigment_map {
[0.4 image_map { png "test.png" } ]
[0.4 color Cyan ]
}
}
}
So on the front you should see the image of test.png (in the attached scene it’s just red). But on some pixels of the front you see the cyan color of the distant half of the cube.
Rendering the scene mutliple times produces the same result.
Rendering the scene at 200×150 is sufficiant.

Task Description
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.
