Download Pixie 1.7.1

Pixie is an open source application for creating photorealistic renders. The development team hopes that Pixie can eventually be used in graphics studies and by people who can’t afford commercial rendering packages. Support for programmable shading, motion blur, depth of field, ray tracing, scan-line rendering, area-light sources and occlusion culling is included. If you are curious about some results after rendering, you can click this page take a look. Version 1.7.1 has recently been released with the following changes since the previous entry in the junk tracker:

Version 1.7.1:

• primitive variables
• gzip compressed input and output
• Netrender and multiprocessor renders dispatch metabuckets
• X11 is optional for linux/unix/osx builds.
• The configure warnings that openExr or fltk are unavailable have been fixed
• docs – wiki based docs
• Issues with Openexr quantization not working have been fixed
• The order of lightsources seen in illuminance loops now matches the RiIlluminate order
• Using an unknown photonmap should no longer crash pixie
• RunProgram support matches the spec closer
• When in the context of a RunProgram, RiBegin starts a ribout context on stdout, when given a null argument in a runProgram will output to stdout. Previously it (incorrectly) started a separate render.
• Parsing of nested ReadArchives has been fixed
• Subdivision surfaces – better error detection for degenerate surfaces
• The displacement and surface shadeops calls no longer give errors when loading the shader, or queying it via sdrinfo or the sdr library
• The sdr library can tell you if the variable is writable
• The sdrinfo tool will print “output ” before output variables
• Pixie will print the current statistics if it recieves sighup
• The message passing functions may have crashed if they didn’t find the requested parameter, this is now fixed.

Version 1.6.3:

• Better automake scripts
• fixes to the spherelight and quadlight hcshaders
• gather no longer produces odd results if the shader doesn’t use N
• quality improvements to LOD
• Oi and Ci recieve defaults if the shader doesn’t fill them in
• fixed a bug with motion blurred subdivision surfaces
• user SL functions which take no arguments may now be uniform
