If a point (x#,y#,z#) lies somewhere on a triangle (A,B,C), and the three triangle vertices all have different normals, how do you interpolate what the normal should be at the point in question?
Point=x,y,z
Triangle=
Ax,Ay,Az
Bx,By,Bz
Cx,Cy,Cz
Anx,Any,Anz
Bnx,Bny,Bnz
Cnx,Cny,Cnz
What should the normal be at the point (x,y,z)?
This is for a lightmapper. I need to figure out the normal at each point, so I can make the light appear smooth.
