README

        
A toy implementation of so-called "Material Point Method" to understand if i'm able to implement a physics-related paper.

Turns out, i am :).

Uses OpenGL for particle visualization, CUDA for (some) parallel processing, GLM for linear algebra operations, Eigen for matrix operations not included in GLM (e.g. SVD matrix decomposition).

Realtime demos (the first is the freshest :))

TODO

[x] APIC

[ ] Implicit time integration

[ ] Multithreading for all MPM stages

[ ] Volume rendering or sth idk separate particles are (not) fine
