Hi there TD communinty.
The above tutorial shows a couple of handy techniques i picked up working with point files.
For the tutorial you need: Touchdesigner, Blender (2.9+) and Meshlab.
Both are completely free.
The tutorial has roughly 3 parts
part 1 shows an easy way to blend point files created from sops in touchdesinger
part 2 shows how to optimize meshes using blender and meshlab
part 3 shows how to create point files with exact vertex count and how to handle color.
again, there is some music running in the background. if you don´t like it mute it.
if you like it you may buy it here: LCSM-earthbound
