Hello im trying to warp image using nurb mesh. I have some good results, but still need some help.
My first question is how to get image (bitmapData) from nurb plane to bitmap image or movie clip.
Second question : can i apply nurb to simple plane (not with nurb mesh), so i could have irregular nurb points (not in a grid like right now).
