PPT-Summary of Properties of 3D Affine Transformations

Affine transformations preserve affine combinations of points Affine transformations preserve lines and planes Parallelism of lines and planes is preserved The columns of the matrix reveal the transformed coordinate frame. 1 2D Transformations Given a point cloud polygon or sampled parametric curve w e can use transformations for several purposes 1 Change coordinate frames world window viewport devic e etc 2 Compose objects of simple parts with local scaleposition orie Isophote enumeration .
