Has anyone here done a voxel to mesh algorithm that runs:

 

In CPU

Every frame

only the voxels that are in field of view

only the faces that face the camera

 

was it fast enoughff?

I saw a GDC talk that used marching cubes to generate geometry for signed distance fields, which is somewhat similar to your voxel problem.  However, the author didn't do any backface/frustum culling and it was done using compute shaders.  So you could definitely make it work on CPU, but it wouldn't scale as well as doing it on GPU.

 

Here are the slides if you're interested
