Transforms between coordinate systems. After using dxTFormNormal the new components can be read with dxTFormedX(), dxTFormedY() and dxTFormedZ(). This is exactly the same as dxTFormVector but with one added feature. After the transformation the new vector is 'normalized', meaning it is scaled to have length 1. For example, suppose the result of dxTFormVector is (1,2,2). This vector has length Sqr( 1*1 + 2*2 + 2*2 ) = Sqr( 9 ) = 3. This means dxTFormNormal would produce ( 1/3, 2/3, 2/3 ). |
