Does retopology increase the shape accuracy?

[Victor Ramamoorthy]

If I start with a dense cloud, create a mesh and use retopology to finely divide the mesh, does it increase the shape accuracy or just redivide the old mesh? Thanks.

To make my point clear, does retopology use dense cloud that was the starting point and rebuilds the mesh with photometric optimizations?

Most people who sell models prefer a clean mesh of quads.

They call most scan art triangle soup. I use zbrush remesh tool which has a slider to reduce polygons because I make real time art not a piece that requires rendering for minutes or longer each frame

If your art piece will animate topology and clean quads is important

To answer your original question I think you will lose some sharp details using a retopology tool

I'm fairly certain re-topology doesn't utilize photo-metric optimizations.

Hi Victor,

I confirm that the retopology is only a post processing filter. It will most likely result in loss of details. However, remember you can apply the retopology filter also on a triangle selection and not necessarily to the whole mesh!

Thanks for the clarifications Andrea and CG-guy.
