C++ (Cpp) Matrix44::GetRotation示例

void NiGeometryData::Transform( const Matrix44 & transform ) {
	Matrix44 rotation = Matrix44( transform.GetRotation() );

	//Apply the transformations
	for ( unsigned int i = 0; i < vertices.size(); ++i ) {
		vertices[i] = transform * vertices[i];
	}
	for ( unsigned int i = 0; i < normals.size(); ++i ) {
		normals[i] = rotation * normals[i];
	}
	CalcAxisAlignedBox(vertices, center, radius);
}
