3Delight supports many of the features required to produce photrealistic images including motion blur, depth of field, programmable shaders, antialiasing and ray tracing. 3dom De Panne stands for 3-Dimensional Object Modeler. Eraserhead GML a ray-tracer. The project is licensed under the GNU General Public License g3d a simple 3D modeller. A heightfield is a grid with values determining altitude.
Main goal is a powerful modeler for photo realistic images and animations.
It takes a 3D scene description, and outputs a representation of this scene in a 2D image. Primal Form a 3D modeler for UNIX distributed under the GNU General Public License. It implements the matrix, progressive, and wavelet radiosity with clustering methods. It also comes with a visualisation front-end useful for interactive scene rendering or teaching. It is meant to be a tool for those who want to generate digital terrain models for use in raytracing or other simulations.
