Hi I'm trying to export a 2d track into 3d space. I've brought in the data through chops and fitted it to uv space (0-1) through a range node (1-2048 in x, 1-1556 in y).
My first try was to use a grid at a certain point to project uv cordinates from camera… and transfering attributes between chops and the grid with point sops and finally a transfer attribute that copies color with the 3d information in it to the tracking point. In short this technique worked, but the metaball sampling doesn't seem to be accurate enough and I get random jumps. I've tried playing with the kernel values but nothing makes it better.
Could any ones suggest a more intelligent (and accurate) approach?
