Hey! just thought I''d say... I have nearly finished this little app I started making last night... it generates the glVertex3f co-ordinates for a square and triangle.. at the mo I have it so that it will generate the code for a flat square and triangle and a 3D cube just have to add the 3D triangle bit then test it properly... quite handy... but I think I may have to change a few bits.... but that won''t take long... The only problem is that it assumes the point of origin is 0.0, 0.0, 0.0 and works the coordinates out from the user giving a size (length and width etc..) and a position on the z axis... quite handy although its only a simple VB app. Im sure it will help a few people when its ready Alan IF YA SMELL... WHAT THE BEZZ IS COOKIN''''
