MSet_Vertex_Normals


Functions

void MSet_Vertex_Normals (HC_KEY key, int offset, int count, const HC_POINT *normals)

Function Documentation

void MSet_Vertex_Normals ( HC_KEY  key,
int  offset,
int  count,
const HC_POINT *  normals 
)

Speedily sets the drawing attributes on a large number of shell, mesh, or polycylinder vertices.

Parameters:
key The unique identifier returned by a previous call to KInsert_Mesh(), or KInsert_Shell().
offset Number of the point in the surface definition at which to start work. "0" is the first offset value.
count The number of normals contained in normals.
normals Vector of x-y-z normal values. A simple N x 3 array may also be used. Passed by reference always.

DETAILS

The "normal" mode of setting an attribute value on a single shell or mesh vertex is to open the geometry, open the vertex, set the attribute, close the vertex, open the next vertex, set the next attribute, close the vertex, etc. This can be tedious if a large number of vertices need to be set up. The "MSet Vertex" ("Multi-Set") routines are provided as a convenience to speed up the process.
