const  SG_ALL_TRIANGLES*  sgC3DObject::GetTriangles() const

 

Description:

Returns the pointer to the structure of a 3D object triangles description.

 

Arguments:

No arguments.

 

Returned value:

Returns the pointer to the structure of a 3D object triangles description.

 

The description of this structure:

typedef struct

{

 int                                        nTr;

 SG_POINT*                       allVertex;

 SG_VECTOR*                  allNormals;

 double*                               allUV;

} SG_ALL_TRIANGLES;

 

nTr - the number of triangles describing a 3D object

allVertex - array of point triples each is a triangle vertex

allNormals - array of normals in the corresponding points of the allVertex array

allUV - array of the U and V texture coordinates in every triangle vertex.

 

 

If the object is not triangulated, NULL is returned. To triangulate the object, you need to use the sgC3DObject::Triangulate function
