Manipulating Particle Motion with Stardust Particle Engine – Part 1 | Envato Tuts+

Stardust Particle Engine provides two major approaches to freely manipulate particle motion, namely gravitational fields and deflectors. Gravitational fields are vector fields that affect a particle's acceleration, and deflectors manipulate both a particle's position and velocity. The first part of this tutorial covers the basics of particle motion and gravitational fields. Also, it demonstrates h
