C++ (Cpp) Transformable::rotate Examples

Example #1

File: transformable_tests.cpp Project: meuter/tiny

TEST(Transformable_objects, can_be_rotated)
{
	Transformable t;
	quat rotationX(Transformable::X_AXIS, toRadian(90));
	quat rotationY(Transformable::Y_AXIS, toRadian(180));


	EXPECT_EQ(quat(0,0,0,1), t.rotation());
	t.rotateTo(rotationX);
	EXPECT_EQ(normalize(rotationX), t.rotation());
	t.rotateTo(Transformable::Y_AXIS, toRadian(180));
	EXPECT_EQ(normalize(rotationY), t.rotation());
	t.rotate(quat(Transformable::X_AXIS, toRadian(90)));
	EXPECT_EQ(normalize(rotationX * rotationY), t.rotation());
	t.rotate(Transformable::X_AXIS, toRadian(-90));
	EXPECT_EQ(normalize(rotationY), t.rotation());
}
