示例1: reflectOrientation
/// \param angles The orientation (unit) vector that you want to reflect
/// \return Euler angles that are reflected about the slope of the plane.
EulerAngles Plane::reflectOrientation(const EulerAngles& angles) const
{
EulerAngles out;
Vector3 look, up, right;
RotationMatrix rotMat;
// get look and up vector from euler angles
rotMat.setup(angles);
look = rotMat.objectToInertial(Vector3(0.0f,0.0f,1.0f));
up = rotMat.objectToInertial(Vector3(0.0f,1.0f,0.0f));
// reflect the look and up vectors over the plane
look = reflectOrientation(look);
up = -reflectOrientation(up);
// calculate right vector
right = Vector3::crossProduct( up, look);
right.normalize();
// create a rotation matrix from right, up, and look
rotMat.m11 = right.x; rotMat.m12 = right.y; rotMat.m13 = right.z;
rotMat.m21 = up.x; rotMat.m22 = up.y; rotMat.m23 = up.z;
rotMat.m31 = look.x; rotMat.m32 = look.y; rotMat.m33 = look.z;
// calculate new euler angles from the matrix
out.fromRotationMatrix(rotMat);
return out;
