RwSetPolygonAmbient(RwPolygon3d *polygon, RwReal ka);
Description
Sets the ambient reflection coefficient of the polygon’s material.
Arguments
polygon Pointer to the polygon.
ka Ambient reflection coefficient in the range CREAL(0.0) to CREAL(1.0).
Return Value
The argument polygon if successful, and NULL otherwise.
Comments
RenderWare optimizes memory usage by sharing materials across multiple polygons. Setting a polygon material property with this function will cause the polygon to have it’s own copy of the material, not shared by any other polygons. Unless this is the desired effect, it is more memory efficient to use the corresponding material function RwSetMaterialAmbient() to change the underlying polygon material. This change will then be propagated to all polygons which use the material. The following line of code demonstrates how this is achieved:
RwSetMaterialAmbient(RwGetPolygonMaterial(polygon), ka);
