Aqsis is a cross-platform photorealistic 3D rendering solution, based on the RenderMan interface standard defined by Pixar Animation Studios.
Focusing on stability and production usage, features include constructive solid geometry, depth-of-field, extensible shading engine (DSOs), instancing
... [More], level-of-detail, motion blur, NURBS, procedural plugins, programmable shading, subdivision surfaces, subpixel displacements and more. [Less]
Open CASCADE Community Edition: patches/improvements/experiments contributed by users over the official Open CASCADE library. It was created due to dissatisfaction with OCC's lack of transparency or a public repository. A repository was created at https://github.com/tpaviot/oce
... [More] Technology (OCCT) is an open source software development platform. It includes components for 3D surface and solid modeling, visualization, data exchange and rapid application development. It can be applied in development of numerical simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM applications.
OCCT traces its history to the mid 1990s. [Less]
Pixie is a photorealistic renderer that uses a RenderMan-like interface. Features include programmable shading, motion blur, depth of field, raytracing, scan-line rendering, occlusion culling, global illumination, caustics ...
This package implements many of the NURBS routines in Piegl's book using Fortran. It provides Python bindings for these functions using f2py. Finally we provide a NURBS class which uses this functionality for the simplified, manually creation of geometry for use in isogeometric analysis.
