VMI VCG Mesh Image.
|
|
The vmi image file consists of a header containing the description of the vertex and face type,
|
|
the length of vectors containing vertices of faces and the memory image of the object mesh as it is when
|
|
passed to the function Save(SaveMeshType m)
|
|
NOTE: THIS IS NOT A FILE FORMAT. IT IS ONLY USEFUL FOR DUMPING MESH IMAGES FOR DEBUG PURPOSE.
|
|
Example of use: say you are running a time consuming mesh processing and you want to save intermediate
|
|
state, but no file format support all the attributes you need in your vertex/face type.
|
|
NOTE2: At the present if you add members to your TriMesh these will NOT be saved. More precisely, this file and
|
|
import_vmi must be updated to reflect changes in vcg/complex/trimesh/base.h
