just wanted to ask if there is a node or module for linear interpolation in triangles?
i’d like to generate an interpolated normal of the point i get from Intersect (3d Mesh Ray), depending on the normals i get from the three vertices of the face the point is in.
something like this: http://local.wasp.uwa.edu.au/~pbourke/texture_colour/interpolation/
this is for cpu purposes only. from what i understand something similar is done for phong shading, but i just can’t get my head around it :(
