示例1: test_oo_examples
def test_oo_examples(self):
from pyrr import Quaternion, Matrix44, Vector3
import numpy as np
point = Vector3([1.,2.,3.])
orientation = Quaternion()
translation = Vector3()
scale = Vector3([1.,1.,1.])
# translate along X by 1
translation += [1.0, 0.0, 0.0]
# rotate about Y by pi/2
rotation = Quaternion.from_y_rotation(np.pi / 2.0)
orientation = rotation * orientation
# create a matrix
# start our matrix off using the scale
matrix = Matrix44.from_scale(scale)
# apply our orientation
# we can multiply matricies and quaternions directly!
matrix = matrix * orientation
# apply our translation
translation = Matrix44.from_translation(translation)
matrix = matrix * translation
# transform our point by the matrix
# vectors are transformable by matrices and quaternions directly
point = matrix * point
