i am currently using solid particles to render many textured boxes. Now for each box i have a bunch of data i’d like to visualize as a heat map on one side of the box. What are the options to implement this?
I was thinking about dynamic texture for each box where i would draw semi transparent circles based on data and then apply that texture to each particle. I expect this solution to be slow.
Second idea was to add more vertices to my boxes and use some vertex shader to color my vertices, is this possible with SPS? Or maybe some fragment shader?
Thanks for any hints
