### 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 do people come up with subdivision schemes?

The subdivision schemes are not arbitrary. Catmull-Clark, arguably the most used subdivision scheme, generalizes bicubic B-splines to meshes of arbitrary topology. Most, other subdivision schemes ...

### What subdivision algorithm advances have occurred since Catmull-Clark?

More of an extended comment than an answer: What do you mean by "optimization and accuracy"? Do you mean computational efficiency for some particular application, like ray tracing, physical ...

### If you can use subdivision surfaces for 2D curves

Subdivision can be used for curves in 2D just as easily as for surfaces in 3D. Usually the subdivision algorithms applied to 2D are called subdivision curves. Subdivision curves do not suffer from the ...

### 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. ...
