Mapping a two-dimensional texture onto a 3D model 1: 3D model without textures 2: Same model with textures. Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models.
On triangular mesh surfaces, the problem of computing this mapping is called mesh parameterization. The parameter domain is the surface that the mesh is mapped onto. Parameterization was mainly used for mapping textures to surfaces. Recently, it has become a powerful tool for many applications in mesh processing.

Face-vertex meshes represent an object as a set of faces and a set of vertices. This is the most widely used mesh representation, being the input typically accepted by modern graphics hardware. Face-vertex meshes improve on VV mesh for modeling in that they allow explicit lookup of the vertices of a face, and the faces surrounding a vertex.
If the mesh becomes tangled or degenerate during simulation, the operators defined on it may no longer give correct values. The mesh may be recreated during simulation (a process called remeshing), but this can also introduce error, since all the existing data points must be mapped onto a new and different set of data points.
FreeCAD is a full-featured CAD/CAE open-source software. Python scripting and various plugin modules are supported, e.g. CAM, Robotics, Meshing and FEM. form•Z (AutoDesSys, Inc.) is a general-purpose solid/surface 3D modeler. Its primary use is for modeling, but it also features photo-realistic rendering and object-centric animation support ...
