C++ (Cpp) extract3x3Matrix Examples

Example #1

File: matrix4.cpp Project: cyecp/vise3d

Matrix Matrix4::getAffineMat() const {
	Matrix result;

	extract3x3Matrix(result.axis);
	result.origin = m[3].xyz();

	return result;
}

Example #2

File: Matrix4.cpp Project: shadercoder/scge

void Matrix4::decomposition(Vector3& position, Vector3& scale, Quaternion& orientation) const
{
	Matrix3 matQ;
	Vector3 vecU;
	extract3x3Matrix().QDUDecomposition( matQ, scale, vecU ); 

	orientation = Quaternion(matQ);
	position = Vector3(m[0][3], m[1][3], m[2][3]);
}

Example #3

File: Matrix4.cpp Project: AlexandreRivet/GraphicEngine

{
    assert(isAffine());

    Matrix3 m3x3;
    extract3x3Matrix(m3x3);

    Matrix3 matQ;
    Vector3 vecU;
