Fluid sphere obstacle
code
comments
It's using a simulation of particles following a flow field.
The flow field is defined by the sum of:
- a constant speed field
- a repulsive field (might be the most technical part of the code)
- some perlin noise
Once the particle paths are computed, replacement technique is used to show particles following them. It's also using interpolation between computed positions of the simulation (tutorial).
A black sphere is then simply drawn, its position and size ahve been adjusted experimentally.
