How are smooth and complex curves and curved surfaces constructed in computers for computer-aided design (CAD)?

Sometimes I take the time to sit down and solve some sudoku puzzles.

I have written these code snippets too often, so I might as well share them.

In order for my 3D modeling application to be useful in the workflow of an architect, I need to be able to import and export document interchange formats such as IFC and STEP.

A little while back, my contract ended with Treble Technologies, for whom I had been writing (parts of) a geometry processing pipeline for automated mesh simplification and mesh cleanup in C++.

I have implemented a voxel data structure similar to an octree, but with a larger branching factor (still powers of 2), that contains a hashmap at the root of the tree.

Undo is a fundamental feature in many software applications, and my app ShapeReality - 3D Modeling is no exception.

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.

One core data structure in my 3D modeling application is a non-manifold polygon mesh data structure.

Half a year ago I embarked on the quest to build a cross-platform, general purpose game engine.

Little-endian means the least-significant byte is at the smallest address (on the left).

With the Vision Pro having made its way into the hands of people outside of Apple’s secretive labs, I want to reflect a bit on my conceptions of what an ideal XR device would look like, and to what extent the Apple Vision Pro comes close to this ideal.

I am preemptively disappointed by the Apple Vision Pro.

A question I get asked a lot is why I decided to build a game engine.

I decided it would be a great idea to implement my own entity component system (ECS).

fully from scratch is not a hill I’m willing to die on, so at least png and gltf import are now done using lodepng and cgltf respectively.

This is just a “hello world”, but I did some work to make it cross-platform / platform agnostic.

My product failed.

Over the summer I decided it was time to let go of Unity due to a variety of reasons, so I picked up the famous Game Engine Architecture book, the Vulkan specification and got to work.

Just today I reached the milestone of 1000 commits for the ShapeReality codebase.
