Hi all,
I'm trying to find UV coordinates within a triangle.
I know the coords of x,y,z and u,v of all 3 points of the triangle but cant seem to find the UV coords if clicked inside the triangle with the mouse pointer.

any help will be much appreciated?

thank you

I too am interested in this, as I would like to make a program similar to tatoo, letting you paint on models texture then save the model back out as a B3D.

Anyone have some example code showing how to do this, would be greatly appreciated.

Thanks,

Ken
