Member Function Documentation

void Ray::transform (  const Matrix4 &    M )

Transforms the ray. Parameters: M  4x4 transformation matrix. Precondition: none. Postcondition: The ray is transformed according to M and its direction is normalized.

void Ray::transformOrigin (  const Matrix4 &    M )  [inline]

Transforms the ray origin. Parameters: M  4x4 transformation matrix. Precondition: ray: { o + y*d | y >- 0 } Postcondition: ray: { M*o + y*d | y >- 0 }
