Pixie is een opensourceapplicatie waarmee fotorealistische renders gemaakt kunnen worden. Het ontwikkelteam hoopt dat Pixie op den duur gebruikt kan worden in grafische onderzoeken en door mensen die zich geen commerciële renderpakketten kunnen veroorloven. Ondersteuning voor onder andere programmable shading, motion blur, depth of field, raytracing, scan-line rendering, area-light sources en occlusion culling is aanwezig. Wie benieuwd is naar een aantal resultaten na het renderen kan op deze pagina een kijkje nemen. Versie 1.6.2 is door de ontwikkelaars enkele dagen geleden de deur uitgedaan met de volgende veranderingen:
Version 1.6.2:
- Improved speed for larger pixel filter sizes
- Multiprocessor support is available via rndr -P:n
- Netrender and multiprocessor temporary file management is much improved
- full path-prefixed files will work correctly
- stale temporary files should not influence new renders
- Netrender and multiprocessor renders support TSM output and baking of irradiance caches
- integer display parameters are supported
- trace() supports "label" and "bias" as additional arguments
- shadow map preparation (MakeShadow) environment and texture preparation is supported for netrender and multiprocessor renders.
- the raytrace hider supports AOVs
- netrender network performance is improved
- arrays may be output as AOVs
- RiDisplayChannel is supported
- fixed an issue where multiple RiReadArchive / DelayedReadArchive which had long argument lists in them could crash
- AOVs which are being output, but are not used in a shader will be computed correctly (eg st where s and t are not referenced in the shader)
- the photometric interpretation of single-channel tiffs matches that for multi-channel tiffs
- significant improvement of texture sampling at the border of textures
- previously color may have bled slightly over the border
- shadow maps which exhibitied thin lines at the edge should now be significantly higher quality
- sdrc searches the contents of the INCLUDE environment variable for headers
- netrenders which used RiBasis will no longer emit a false error message from the client
- the quality of motion blur and DOF has been improved
- there are small increases to speed for DOF
- a potential crash with non-square filters or pixelSamples is fixed
- the filterstep() SL function now works correctly
