GLSL simple & useful tricks #1

The idea behind this series is to provide simple GLSL code, that could do something that would be really hard to make in TouchDesigner alone (or that would require a lot of CPU/GPU time without GLSL).
This time I show how to implement geometry transformations (rotate/scale/translate) for point clouds (or SOP to TOP data).
