Wesley already acknowledged a prob with td.twirl in another thread. Perhaps these problems are related. Both td.ripples and td.fisheye render nothing in the bottom-left quadrant. Also td.fisheye seems to require an unusually large signcurvature value to get much effect. Mac Pro, OS1-.6.8, Max 6, Radeon 5870.

Simple test patcher:

Thanks!

Since you’re going through the texdisplace shaders, have you considered working with jit.gl.pix? It’s really the best and most flexible option for GPU image processing.

WOW… jit.gl.pix looks like a crazy-good GPU treasure chest. I didn’t track its arrival with Max 6. I’ll dive in shortly. Are there any other resources (tutorials, articles, etc.) for learning to harness this beside the object’s help patcher and reference files?

Have a read through the Gen Overview
