Aqsis Description

Free, open source photorealistic, 3D rendering solution Aqsis is a high quality, photorealistic, 3D rendering solution. Aqsis complies with the RenderMan interface standard defined by Pixar.The RenderMan standard has been used in film and television visual effects since it's introduction in 1989. Pixar has used their own implementation for all of their award winning CG features, and provided their implementation for use in the visual effects of most major blockbuster films over the last 2 decades. The Aqsis project offers a way for individuals and organistaions alike to gain experience with the RenderMan interface without the cost of commercial software licenses.Aqsis comprises a tool for compiling shaders in the RSL language, a command line rendering tool, a tool for preparing textures for optimal use, and various developer libraries to enable integration with third party tools. What's New in This Release: Optimizations: · Avoid recomputing samples at overlapping bucket boundaries · CqMatrix Optimisations · Removal of IqBound · Substantially refactored sampling and occlusion culling code · Tight bounding boxes for sampling · Revive old rasterizer code rather than using a sampling tree · New cache-friendly occlusion tree · Occlusion culling prior to micropolygon sampling · Improved sampling speed for RiPoints · Enable the "focusfactor" approximation for depth of field by default · Implement the "motionfactor" approximation for motion blur · Improved shadow map rendering speed · Faster splitting code for large point clouds Other changes: · Piqsl interface refactor · Single window interface · Improved keyboard shortcuts · Improved zooming · Z-buffer support · Texturing improvements · Rewritten environment filtering as part of aqsis_tex · Finer control over texture filtering with "minwidth" and "trunc" parameters. · Smooth shading interpolation for depth of field and motion blur · Matte alpha support for directly rendering shadows on otherwise transparent surfaces · New RIB parser · Better error reporting · Multilayer support for OpenEXR display · Side Effects Houdini plugin Bugs Closed Since 1.4.x: · #2853236 - No AOV for volume shaders · #2853241 - min() not working properly with varying · #2731390 - RiBlobby const opcode not implemented · #2846751 - Camera motion blur not working with points · #2563908 - RiExposure has no effect on empty buckets · #2425031 - ARMan fig 12.12 renders incorrectly · #2270656 - (win32 only) aqsl 1.4.1 crashes on some SL syntax errors · #1102356 - Rudi Cortes' Skin shader · #2834057 - Aqsis failing to compile due to absent of boost-iostreams · #2812953 - shadow("blur") filter artifacts with large values · #2803564 - Scene crash · #2730585 - RiProjection doesn't accept RI_NULL as projection · #2541492 - std::exception / crash on Cylinder prim? · #2012013 - DSO filename confusion/oversight · #2138993 - slxargs sets array length to 1 for non-array parameters · #2846526 - Bad render for image's first row and column · #2853239 - Cannot retrieve string user attributes · #1696939 - CoordSysTransform "NDC" · #2847147 - Bad sampling for combined DoF and MB · #2133952 - smooth shading interpolation artefacts · #1929706 - SDS never split to patches when using facevertex · #2738390 - Transformations prior to a RiProjection() call are ignored · #2843067 - uniform primvars not working with RiPoints · #2813534 - Escaped strings in RSL not working · #2474255 - DoF artifacts at image edges · #2023668 - .aqsisrc on Windows platform · #2838827 - crop command causes artifacts · #2319297 - Flipped surface normals with light transform · #2862585 - Lighting artifact on polygons · #2862549 - Reading an empty RIB produces a syntax error · #2853253 - illuminate(from) not retrieved in volume with illuminance() · #2827244 - large numbers of RiPoints incorrectly bound · #2811298 - parameter passing using lightsource() · #2811297 - odd behavior with match() · #2811281 - arbitrary output variables not working · #2811280 - Incorrect incident ray length in orthogonal projection · #2802439 - AOV not working · #2798384 - Piqsl z buffer · #2730562 - OSX: Running the Aqsis app can "wipe" the users environment · #2644580 - Function overloading in RSL · #2531309 - artifacts with book export in piqsl · #2474067 - DoF not implemented for RiPoints · #2415815 - MPDump FTBFS with GCC 4.X · #2169128 - Comments not parsed in the middle of an array or command. · #2134164 - incorrect normals with orientation-changing transformations · #2084218 - texture() sometimes returns black for entire grids · #2023290 - cube environment map filtering is broken · #2022177 - zoomed images in piqsl not updated during render · #2013783 - Large cracks in subdivision surfaces · #1829339 - Artefacts in SDS render (large micropolygons) · #1431013 - subdivision mesh problem · #1422544 - ShadingInterpolation glitches
