I found @quark’s QuadGrid on the old forum (https://forum.processing.org/two/discussion/11549/texture-on-a-deformed-plane-is-bent-how-do-i-fix-it) and it was exactly what I was looking for but now I’d like to animate it.
Here’s the example I created with just plain QUAD vertices: https://www.dropbox.com/s/gukwz9z4r80orlm/2019walkintest_short.mp4?dl=0
The distortion isn’t a real issue with this image but once you have straight lines it’s kinda ugly. QuadGrid fixes that but I’m not sure how to get the same animation (I change the UV coordinates in the example above): https://www.dropbox.com/s/5pfe6qbiprcx1z2/2019walkintest_quadgrid.mp4?dl=0
Anyone have any ideas? Maybe @quark himself?
