TopMod 3D vs Schama

Works best for Ipad. TopMod is a topological mesh modeler for sculpting intricate, high-genus 3D surfaces right on your iPhone and iPad. Build handles, holes, and complex manifold geometry in real time, then export your creations as OBJ files to use in any 3D pipeline. A focused, self-contained tool for artists, designers, and anyone who loves the mathematics of form.

Schama organizes your 3D file collection, 3D printing, modeling, scans, right on your iPhone and iPad, without ever duplicating your files unless you ask it to. WHY SCHAMA Whether you print in 3D, model, or archive scans, your .stl, .3mf, .usdz, .obj and other files end up scattered across Files, iCloud Drive, and download folders.
