{
    TransformationMatrix matrix;
    for (; currentSpace; currentSpace = currentSpace->parent()) {
        TransformationMatrix localMatrix = currentSpace->matrix();

示例2:

TEST(TransformationMatrixTest, ApplyTransformOrigin) {
  TransformationMatrix matrix;

  // (0,0,0) is a fixed point of this scale.
  // (1,1,1) should be scaled appropriately.
  matrix.scale3d(2, 3, 4);
  EXPECT_EQ(FloatPoint3D(0, 0, 0), matrix.mapPoint(FloatPoint3D(0, 0, 0)));
  EXPECT_EQ(FloatPoint3D(2, 3, -4), matrix.mapPoint(FloatPoint3D(1, 1, -1)));

  // With the transform origin applied, (1,2,3) is the fixed point.
  // (0,0,0) should be scaled according to its distance from (1,2,3).
  matrix.applyTransformOrigin(1, 2, 3);
  EXPECT_EQ(FloatPoint3D(1, 2, 3), matrix.mapPoint(FloatPoint3D(1, 2, 3)));
  EXPECT_EQ(FloatPoint3D(-1, -4, -9), matrix.mapPoint(FloatPoint3D(0, 0, 0)));
}
