Particle dynamics
(MMG640 / MVE080)
Overview
- Simulations in Blender
- What is particle dynamics?
- Particle systems in Blender
Normal workflow
Numerical simulation \(\Rightarrow\) Data \(\Rightarrow\) Visualization (in Blender)
MATLAB / Python / FEM / c-code / etc
Import data in Blender
Blender is also an advanced numerical simulation tool!
Why?
To create realistic physics in animations
Examples of Blender physics simulations
Particle dynamics
A particle system consists of \(N\) points moving in 3D space
\mathbf{r}_i = (x_i,y_i,z_i)\qquad i=0,\ldots, N-1
Newtonian particles: motion governed by
m_i\ddot{\mathbf{r}}_i = \mathrm{F}_i
mass
acceleration
force
(gravity, wind, interactions, etc)
Blender particles
Note: rendering Halo's only works with Blender Render (not with Cycles)
Force fields
Individual field object corresponding to additional external force terms
