Detailed Description

Class to hold a list of verts and possibly how (and if) they are connected.

This class stores three numpy arrays that contain the data for a mesh. Vertices are stored as a two-dimensional array of floats with the rows being individual vertices and the three columns being the X, Y and Z components of the vertices. Normals are stored in the same manner and kept in sync with the vertices. Indices are stored as a two-dimensional array of integers with the rows being the individual faces and the three columns being the indices that refer to the individual vertices.

attributes: a dict with {"value", "opengl_type", "opengl_name"} type in vector2f, vector3f, uniforms, ...
