OK I have worked out how to divide up the space into triangles to create perspective:
http://www.rjprime.co.uk/perspective.html However now I cannot for the life of me get the right matrix to use in the beginBitmapFill function to correctly map a texture. Can anyone help me with being able to map a specific triangle from a bitmap to a specific triangle area on screen. I have calculated the points for both.

Hi Returning to this now as it seems simple distortion is not satisfactory and I do need to have real perspective. I have played a bit with Papervision and it's not too hard to render text with perspective. However the designs that I am working to require quite precise placement and orientation of the text. Using the distort class I could simply specify the 4 points of the plane in 2D space on the stage and render the text like that, but this is not the way Papervision works. My question is, is it possible to render a plane in true perspective just by specifying the 4 points in 2D on the stage? In Zeh's diagram (http://hosted.zeh.com.br/misc/perspective.png) he shows that you can't split the line 50-50 to get the 3D halfway point, is there a way of working out what the proportion would be? If so I want to ammend the distortImage class to take this into account. jake On 03/07/07, Jake Prime <[EMAIL PROTECTED]> wrote: > Hi JC > > Yes as Zeh has illustrated the Sandy distortImage class distorts, and does > not create perspective.
