MeshOBJLoader

This component belongs to the category of the MeshLoaders.

The MeshOBJLoader loads a mesh from a file under the format *.obj. Such a mesh file only supports surface meshes. The *.obj meshes can be generated using software like Blender.

Usage

No pre-requisite in your scene to use a MeshLoader.

Specific mesh loader for OBJ file format.
