Does retopology increase the shape accuracy?

Thanks for the clarifications Andrea and CG-guy.

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!

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

[CG-Guy]

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

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

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.
