B-spline curves - clipping and 3d primitives
B-spline curves are piecewise polynomial cubes with one or more polynomial pieces with a minimum smoothness requirement. For example, a C2 cubic B-spline curve has one or more cubic pieces which are joined in such a way that the resulting composite curve is twice continuously differentiable. B-spline curves have a very elegant expression similar to the Bezier representation with basis function as B-spline functions in place of Bernstein basis polynomials. B-spline basis functions can be computed iteratively using de Boor algorithm.
Sub Classes of Orthographic Projection There are three ordinary sub-classes of Orthographic (axonometric) projections as: 1) Isometric: The direction of projection makes
