Recent upgrades in gentoo stable have caused this bug to resurface. Reference Gentoo Bugzilla Bug 486148 media-gfx/pixie-2.2.6-r1 fails with bison-3 https://bugs.gentoo.org/show_bug.cgi?id=486148 a simple one-line patch is available.

[precomp.cpp:324]: (error) Resource leak: f

dcb — Tue, 27 Aug 2013 11:23:22 -0000

I just ran the static analysis checker "cppcheck" over the
source code of Pixie-2.2.6

It said

[precomp.cpp:324]: (error) Resource leak: f

This looks like a missing call to fclose() to me.

parallel: background area gets blocks of scene

stodd — Tue, 12 Jun 2012 12:59:44 -0000

Using latest Windows install binary: 2.2.6

We have a scene with lots of spheres, with a plain black background. Using multithreaded processing, we see rectangular areas of the background getting filled in with a corresponding rectangular area from the scene. On a 1920x1080 resolution render on a quad-core, we see this in about 25% of images, a few with more than one corrupt area. The problem can be avoided using single threading; this is not a problem for us as we can run multiple versions of the renderer in parallel on different frames.

Our current rib files are large (around 38meg each). We will provide an example, or try to make a simpler version, if you request.

pixie-2.2.6 fails to compile with zlib-1.2.6

Samuli Suominen — Sat, 10 Mar 2012 09:22:12 -0000

pixie-2.2.6 fails to compile with zlib-1.2.5.2 and higher, like the released 1.2.6

downstream bug report: http://bugs.gentoo.org/406899
patch by Helmut Jarausch at: https://bugs.gentoo.org/attachment.cgi?id=304231

the actual compilation errors look like:

environment() segv when called with vector (0,0,1)

Karl Stiefvater — Tue, 21 Jun 2011 20:34:37 -0000

pixie crashes when calling sl environment() with reflection vector (0,0,1)

tracked it to texture.cpp line 1762. variable c is computed to be 0, and then used for division, resulting in NaNs and a crash:

c = (D[COMP_X]*D[COMP_X]+D[COMP_Y]*D[COMP_Y])*2.0*C_PI;

memory error

Anonymous — Sun, 15 May 2011 11:59:52 -0000

Hi,

I am getting a memory error with a Patchmesh of 2048 x 2048.

The error is in

CObject::destroy

I am using

hider "raytrace"

If I use

Hider "stochastic" this does no happen but I get some nasty side effects in the rendered image.

I am using Centos 5.5 .

Any thoughts??

Cheers

apparent shader syntax error

Tony Keele — Thu, 03 Mar 2011 21:59:23 -0000

senario:
compile pixie 2.2.6 on Slackware 13.1 and set the enviroment variables as documentation
run rndr teapot.rib
result:
rather boring teapot and a set of error messages in the form:
./teapot.rib (n): Error in shader "/opt/pixie/shaders/xxxxx.sdr" (0) ("syntax error") (v2.2.6)
./teapot.rib (n): Failed to find shader "xxxxx"
(where n is a line number and xxxxx is the shader name)
diagnosis:
The text files in pixie/shaders are in DOS format with CR/LF line endings while the parser is expecting UNIX files with single \n
and the extra character does not parse
solution:
use the fromdos command (see man pages) to convert the shader files to unix format
result:
much more interesting teapot and no error messages!

All recent pixie versions.

All recent pixie versions.

Rndr crashes. Don\'t know why.

Please contact g g a l i e n s @ n y c a p . r r . c o m regarding solution. Thanks.

sdrc.exe compiles .sl in a wrong way.

Anonymous — Sat, 17 Jul 2010 03:08:54 -0000

I modified sdrc.exe in order to compile .sl with large size macro(simply resize the macro size from 4000 to 40000). However, when I comipiled layeredtexture.sl (using another maya plugins),I found that the compiled .sdr contained an undefined variable named temporary_27 in code segment.
I've checked the source code and found that the variable list indeed had pushed the variable,but when wrote the variables to .sdr,the number of variables changed from 223 to 222 and temporary_27 was gone !
