| - | To create more complex meshes one can use also tetrahedral mesh, which can be obtained (with one intermediate step) from 3D modeling software, like [[http://www.blender.org|Blender]]. Software tools for 3D modeling usually do not provide mesh itself, however they can save some files, e.g. in STL format that can be directly used for mesh generation. Then, a mesh generating software is used, like [[http://wias-berlin.de/software/tetgen/|Tetgen]]. | + | To create more complex meshes one can use also tetrahedral mesh, which can be obtained (with one intermediate step) from 3D modeling software, like [[http://www.blender.org|Blender]].

| + | Note that the mesh creation, namely the conversion from your favorite 3D modeler via Tetgen can be sometimes complicated process. In general it is good to start with simple objects and if the whole toolchain works, increase the complexity. | ||

| + | Here is an example of the procedure step-by-step, for much simpler object than a cow. | ||
