### Visualizing the Lane-Riesenfeld Algorithm

The Lane-Riesenfeld algorithm subdivides the control polygon of a B-spline to create a new control polygon with the same limit spline. It's made up of two steps: first, duplicating all of the control ...

### How to smooth out a voxel grid?

If you have this data in a 3d array where a block is a 1 and no block is a 0 you can apply a 3d blur and then set all voxels that are left with a value higher than 0.5 to 1 and those that arent to 0. ...
