3dom stands for 3-Dimensional Object Modeler. The aim of 3dom is to offer a tool to model reality with user-chosen accuracy, and user-chosen inclination for a particular purpose, which can be gradually improved and extended. 3dom is designed to be a general-purpose modeler, however it is especially inclined to model scenes for Global Illumination purposes.
The Free Animation and Modeling Project (or FAMP), is a project to create a full-featured 3-Dimensional Modeling and Animation System. FAMP shall include support for animation, animated modeling. FAMP already includes the ability to extend easily without modifying code thanks to a plug-in architecture.
GtkGLMaterialDialogis a GTK+ dialog that can be used to edit 3D-object material properties. It is based on the material properties of OpenGL with diffuse, ambient, specular, emissive colors (RGBA), and a specular coefficient (shininess). The material is previewed by rendering a lit OpenGL sphere in a gtkglarea widget.
The GNU Triangulated Surface Library (GTS) provides a set of useful functions to deal with 3D surfaces meshed with interconnected triangles. It features metric operations (area, volume, curvature, etc.), 2D Delaunay and constrained Delaunay triangulations, robust geometric predicates and set operations on surfaces (union, intersection, etc.), surface refinement and coarsening (multiresolution models), and bounding-boxes trees for collision/intersection detection.
Terraform allows you to create fractal terrain (also called a height field) and transform it using a number of algorithms. It is meant to be a tool for those who want to generate digital terrain models for use in raytracing or other simulations. Terraform features different views and colormaps and has a preview mode which features interactive real-time rotation of the terrain object. Terraform is written for the GNOME desktop environment.
