This repository is for the Advanced Computer Graphics course given at Chalmers University of Technology.
A real time GPU(cuda) smoke simulator was implemented (Visual Simulation of Smoke, Stable Fluids), based on gird method, using semi-lagrance method and linear interpolation. A render using ray marching to perform self-shadowing is provide. And in order to speed up rendering in our lab machine which uses llvm opengl (cpu), the light intensive of each voxel is computed by a cuda kernel too.
Some results are showed below:
| empty | sphere | cube |
|---|---|---|
 |
 |
 |
Now, this simulator can run at 30fps for gird size: 50 * 50 * 50 (real time!).
| render pipeline | gpu |
|---|---|
 |
 |
A simple voxelizer, scans each layer of the object.
| mesh | voxelized |
|---|---|
 |

It can run in chalmers remote machine now, we fixed the depended libs. But still, due to opengl setting of remote machine, which uses llvm render, it cannot use the gpu directly.

if there are any environment problems, you can try to install these dependency yourself.
