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 1.5.6 is door de ontwikkelaars de deur uitgedaan met de volgende veranderingen:
GI/irradiancecache improvements:OpenEXR support:
- maxError is now 1.0 by default
- memory consumption during GI baking is much improved
OpenEXR support has tentatively been added. Not all compilers / platforms appear to support this yet.
Subdivision Surfaces:
Pixie detects OpenEXR support, but the check for OpenEXR needs to be told where to look if the libs are not in the standard /usr/lib location.
It can also be told to link in statically. Both are options to configure:
--with-openexr-prefix=/path/to/openexr/install/location/
--enable-static-openexr
This enables an OpenEXR display driver to output OpenEXRsSubdivision surfaces should now displace properly and their rendering has been improved in meshes with creases specified
Raster Oriented Dicing:There are three new attributes (for the zBuffer and hidden hiders)
Other Changes / fixes:
"dice" "rasterorient" 1 - 0=nonrasteroriented dicing
"cull" "backfacing" 1 - 0=don't cull backfaces (for bake and GI)
"cull" "hidden" 1 - 0=don't cull hidden surfaces (for bake and GI)
These do the following (respectively) backface culling is disabled for unshaded objects (they're shaded regardless) hiding of unshaded grids is disabled the dicing metric is determined in 3d raster-space rather than 2d raster. Either way, the visual result (which uses shaded grids) should be the same.
This is really useful for situations where the side-effects of running the shader are the important output of a render - eg irradiance cache generation. The generated caches will be valid from more angles than without these options.[break]De volgende vijf downloads staan klaar:
- Corrected man page for texmake (the cube map face orders now match the program)
- RiTransformEnd should properly maintain the 'handedness' of the current transform
- fixed an issue where the RiSubdivisionSurface might alter the spline basis functions in the current attributes
- String handles for lights are properly handled
- Environment lookup is fixed
