Thanks Sean!
I’ll be updating it. I plan to add:
- vertex shader animated distortion to the outer vessel walls (just a small amount).
- white blood cells
- vector field flow thanks to Jonathan(cccprobot). Granted, this won’t work yet for mesh (CPU) particles, but I’ll be ready for when Niagra hits! I may try a version with all GPU particles just to visualize the flow, and use normal-mapped sprites.
BTW, I now have dynamically tessellated (displaced) white blood cells as particles, and there is not really any slowdown! That’s crazy!
