View Full Version : How to compute texture coordinates?
Given a triangle with its vertices and the texture coordinates at each vertex known, is there anyway of finding the texture coordinates of a point on that triangle?

What do you mean by
texture coordinates of a point on that triangle
if there is a point which falls within this triangle, is it possible to obtain the texture coordinates of this particular point?

hmmm ok i think it should be possible,
your 3 triangle vertices are v1,v2,v3, your new point is p and your tex-coordinates are t1,t2,t3 (as glTexCoord2*) and your new tex coord is tp
now you can setup to equations in vector notation
with that ist should be possible to solve those equations for your new tex coord.
hope that helps
u want barycentric coordinate i think my friend
