Constructor & Destructor Documentation

RDGeom::Transform3D::Transform3D

(

)

[inline]

Constructor.

Initialize to an identity matrix transformation. This is a 4x4 matrix that includes the rotation and translation parts see Foley's "Introduction to Computer Graphics" for the representation

Operator *= and = are provided by the parent class square matrix. Operator *= needs some explanation, since the order matters. This transform gets set to the combination other and the current state of this transform If this_old and this_new are the states of this object before and after this function we have this_new(point) = this_old(other(point))
