Python Matrix33.from_eulers Examples

Example #1

File: cube.py Project: KnowNamee/bsu-rendering

 def render(self, time: float, frametime: float):
     self.ctx.enable(moderngl.DEPTH_TEST | moderngl.CULL_FACE)
     self.ctx.clear(1.0, 1.0, 0.5, 1.0)
     self.rotation.value = tuple(
         Matrix33.from_eulers((time/2, time/2, time/2)).reshape(9).tolist())
     self.prog['time'].value = time
     self.texture.use(location=0)
     self.cube.render(self.prog)

Example #2

File: test_equivalence.py Project: adamlwgriffiths/Pyrr

     m = Matrix33.from_x_rotation(np.pi / 2.)
     q = Quaternion.from_x_rotation(np.pi / 2.)
     qm = Matrix33.from_quaternion(q)
     em = Matrix33.from_eulers(eulers)
     self.assertTrue(np.allclose(qm, m))
     self.assertTrue(np.allclose(qm, em))
     self.assertTrue(np.allclose(m, em))
