Hi Babylonians, I'm sorry I haven't been here much lately, but I'm burried in math hell - if there is such a place - alright, there is. I have a painting app - will post this soon once I've rebuilt the node server ( I haven't posted yet because multiuser is the main point). But I'm continuing to build on our old server to add features to test. So, here is the question - Does anyone have any math to translate x.y pointer events to UV mapping coodinates to piant locally on an object? I currently have the old standards working (unwrap UVs and paint on a plane to reflect the 3D objects UVs.) However, I'm sure there is a way to unwrap the UVs based upon the object your unwraping to allow real time painting locally from the 2D canvas to a dynamic texture. I can work the math on a specific object, but that's not good enough. Any thoughts from the brainiacs here? DB
