Linear transforms

Linear Transforms by Robert Rayment. This is maybe 'old hat' to some of you. It shows in pure VB, apart from loading bitmaps & set & get pixels, how to map a rectangular bitmap area onto a non-reeentrant quadrilateral, a circle, cylinder, right-circular cone and a sphere. I've stopped short of automating the shapes and saving the transfoms so you need to change the parameters in the code to get variations. Hopefully the comments are sufficient for you to do with it as you wish! Zip file 145KB (With some bitmaps).
