| Compress an array of vertices (i.e. remove all duplicated vertices). Returns an array of csCompressVertex which can be used to map from the old index to the new one. The 'vertices' table will be modified with the new compressed vertices. If this function returns 0 there is nothing to do (i.e. no duplicate vertices). Otherwise you have to 'delete[]' the returned array.

Compress an array of vertices (i.e.

remove all duplicated vertices). Returns an array of csCompressVertex which can be used to map from the old index to the new one. 'new_count' will be set to the new number of unique vertices (and 'new_vertices' will be the new vertex table with that size). The size of the returned array is 'num_vertices' though since it has to be indexed with the original vertex array. If this function returns 0 there is nothing to do (i.e. no duplicate vertices). Otherwise you have to 'delete[]' the returned array.
