iOS app launched: 3D modeling on iPhone and iPad
28 July 2025
Tags: Geometry
For the past 2 months I have been working on a 3D modeling app for iOS devices using C++ and Swift, and I just released it on iOS.
This release is the product of a self-proposed bet with a friend that I would have to pay him €1000 if I did not launch some application he could install and use within 3 months.
It supports:
- Non-manifold polygon meshes with loose vertices and edges (see An editable non-manifold polygon mesh data structure)
- Inserting vertices, edges and faces
- Extruding edges and faces
- Deleting elements
- Duplicating elements
- Multi element selection
- Flipping face normals
- Insert primitive shapes
- Saving and loading to and from .obj (note that all geometry will be merged into one mesh)
- Orbit camera viewport navigation
