示例1: CalculateDirectionalLight
void CalculateDirectionalLight(Vertex_VCN *pVertices, int num_vertices, Vector4 &light_direction, Vector4 &light_color)
{
for ( int i=0; i<num_vertices; i++ )
{
Vector4 normal = g_world_matrix.RotateVector(pVertices[i].m_Normal);
Vector4 intensity = VectorDot(normal, light_direction);
intensity.Abs();
pVertices[i].m_Color = intensity * light_color;
}
