| Solid Modeling, Visualisation and Simulation |
| This page tries to provide a little survey into the technologies and free resources available for the purpose of creation of solid models and its visualisation. |
Voxel Simulate solid using particles (nuage de points) in 3 space. For some impressive animation created using voxel technology : Library for implementing voxel - Volpack the volume rendering library from Stanford U. The VolPack Volume Rendering Library also a voxel viewer for windows VoxView . |
Meshing Simulate solid with basic geometrical elements usually tetrahedra or hexahedra. Key technology include automatic mesh generation. For example, to create a mesh for a solid object, nodes are first placed at the vertices of the object. Nodes are then distributed along the curves surfaces. The surfaces of the object are then divided into triangles or quadrilaterals using the nodes that were defined. These set of meshed surface areas defines a closed volume which represents the solid object. The volume itself is then mesh using tetrahedra, hexahedra or mixture of the two basic elements. Steve Owen provides a very comprehensive survey on mesh generation technologies and the software available at: |
