home.iitk.ac.inAffine transformations of the coordinate system do not change the shape of the B-spline curve. Increasing the degree of the curve makes it more difficult to control, and hence a cubic B-spline is sufficient for a majority of applications. Rao, CAD/CAM Principles and Applications, 2010, TMH ...

3D TRANSFORMATIONS - IIT Delhi
web.iitd.ac.inGeometric transformations are mappings from one coordinate system onto itself. The geometric model undergoes change relative to its MCS (Model Coordinate System) The Transformations are applied to an object represented by point sets. Rigid Body Motion: The relative distances between object particles remain constant Affine and Non-Affine maps

As the “Homogeneous Coordinates” sidebar explains, by representing each vertex in homogeneous coordinates, the graphics system can perform the entire hierarchy of transformations simultaneously with a single matrix-vector multiply. The need for efficient

Affine Transformations - University of Texas at Austin
www.cs.utexas.eduAffine transformations In order to incorporate the idea that both the basis and the origin can change, we augment the linear space u, v with an origin t. Note that while u and v are basis vectors, the origin t is a point. We call u, v, and t (basis and origin) a frame for an affine space. Then, we can represent a change of frame as:
