Function Documentation

int LOD_CollapseEdge

(

LOD_Decimation_InfoPtr

info

)

Once both the stages above have been completed this function collapses a single edge in the mesh. The LOD_Decimation_Info structure is updated to represent the new mesh.

Returns:

1 if an edge was collapsed.

0 if no suitable edge was found to be collapsable You should stop calling this method in this case

Warning:

Do not expect that the order of polygons, vertices or vertex normals will be preserved by this operation. This function returns a packed array of polygons and vertices and so necessarily the order will be different. This means you should not expect to find the same polygon in the same place in the polygon array after this function has been called.

int LOD_FreeDecimationData

(

)

Free any memory the decimation process used during the decimation process

Returns:

1 if internal data successfully freed

0 if no data was freed

int LOD_LoadMesh

(

LOD_Decimation_InfoPtr

info

)
