/**
|
|
* The ViewProviderMeshFaceSet class creates nodes for representing the mesh
|
|
* data structure. Depending on the size of the mesh it uses two ways to
|
|
* render it:
|
|
* - For huge meshes it renders directly the data structure. Rendering directly
|
|
* the data structure has the advantage to save memory by not creating the
|
|
* according OpenInventor nodes which would more or less duplicate the
|
|
* memory for a mesh. Especially for huge with several hundred thousands or
|
|
* even millions of triangles, the amount of saved memory is considerable.
|
|
* - For all other meshes it uses the appropriate OpenInventor nodes. Although
|
|
* this needs more memory its usage is much more flexible. It offers several
|
|
* nice features like a smooth-shaded appearance of a mesh whereas the
|
|
* OpenInventor nodes are already capable to do everything automatically,
|
|
* or the usage with textures.
|
|
*

|
* For more details @see SoFCMeshNode and SoFCMeshFaceSet.
