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.
Animadead is a skeletal animation library designed to load and play skeletal animations. It supports models that are composed of several swappable meshes bound to a single skeleton that can be driven by multiple animations. There is an export plug-in for Maya, and others are in development, including plug-ins for 3D Studio Max and Lightwave. It is written in C++ and has no dependencies. However, an example implementation is provided that uses OpenGL and SDL.
Ayam is a free 3D modelling environment for the RenderMan interface. It features good RIB export, CSG (all RenderMan primitives supported), and NURBS modelling. Features instancing, arbitrary number of modeling views, object clipboard, independent property clipboard, n-level undo, console, and Tree-View with Drag-and-Drop support.
The Java 3D API enables the creation of three-dimensional graphics applications and Internet-based 3D applets. It provides high-level constructs for creating and manipulating 3D geometry and building the structures used in rendering that geometry. With this software, you can efficiently define and render very large virtual worlds. Blackdown's version of Java 3D uses the OpenGL low-level API to take advantage of 3D hardware acceleration.
