The D3D_OVERLOADS constructors for the D3DTLVERTEX structure offer a convenient way for C++ programmers to create transformed and lit vertices.
_D3DTLVERTEX() { }
_D3DTLVERTEX(const D3DVECTOR& v, float _rhw,
D3DCOLOR _color, D3DCOLOR _specular,
float _tu, float _tv)
{ sx = v.x; sy = v.y; sz = v.z; rhw = _rhw;
color = _color; specular = _specular;
tu = _tu; tv = _tv;
}
