The D3D_OVERLOADS constructors for the D3DLVERTEX structure offer a convenient way for C++ programmers to create lit vertices.
_D3DLVERTEX() { }
_D3DLVERTEX(const D3DVECTOR& v,
D3DCOLOR _color, D3DCOLOR _specular,
float _tu, float _tv)
{ x = v.x; y = v.y; z = v.z; dwReserved = 0;
color = _color; specular = _specular;
tu = _tu; tv = _tv;
}
