It would be great to explore HDRI image manipulation in copernicus as animated reflection and light maps for motion graphics.

I've started with trying to distort an image and checking its projection back on a sphere.

Not as simple as I expected - weighting distortion with a horizontal ramp to spread the pixels out for the poles at the top and bottom of the image. weighted distortion graphics [graphicdesign.stackexchange.com]

Any ideas/suggestions/recommendations much appreciated thanks!

Thanks loads for that Jeff. It will come in very handy. I need to look into the code more to understand it but I get the gist from your description thankyou.
Techie - although not an exact rendering of the visualizer I really like the look you managed to get out of it. Is it almost doing the same thing as Jeffs code - your projecting the vector onto Hue and using the length for saturation?
Lots to do in the openCL node

Hello I've been playing with the flow options converting noise patterns to velocity via the Slope sop.
I really like the colours as displayed in the SLOPE SOP and would like to export them as RGB.
The problem I have when doing a UV to RGB is that colours change.
Does anyone know how to conserve the colours?
I thought this was simple but I've ended up doing a deep dive on layer properties and see from inside the sope sop
that its type is 'vector' as a opposed to 'color'. And I'm guessing that its doing something to display it in RGB for us, the U and V set to R and G with some scaling but how is the B ?
Any thoughts much appreciated thanks
