GLSL Question

Postby DmitriyEvent » Mon Aug 19, 2019 8:34 am

Hi all!

I stock with one problem about GLSL. Now when i take my point cloud and add some turbulence into that, its looks cool but how can i calculate direction in which my hand are moving? i know formulas of velocity or magnitude and how to implement them in code but how and where i have to apply that? Main question how can i calculate velocity for my hand movement for example use glsl only

You probably want to research 'optical flow' techniques to start. You can go into the Palette > Tools and you will find an opticalFlow component already there, with a GLSL TOP inside doing the work. Maybe a good starting point.
