Any updates on how this can be done? I have implemented my own methods to do
this, but they are very slow and buggy.
To take step back again, the overarching goal is to have a user select n points
on a body that bound a region that a picture will be projected on to.
Projecting textures with TexGen works great as a "guideline" for the user, but
they map to all surfaces in view, not just the desired surface. In addition, I
actually need the nodes for area calculations. And as mentioned, I don't know
if the there is anyway to extract this information from TexGen.
Currently, the process is as follows:
1. Project entire image onto model with TexGen
2. Align the image where you'd like it to be on the model
3. With image overlaying the body, select n points that will serve as the
boundary for the texture
4. Capture the points that lie within this boundary:
a. Capture all visible nodes (this is the part I'm still having trouble
with)
b. Loop over all visible nodes and check if they lie within boundary
Thanks for all that help. Appreciate your time!
