Halfspace experimental IDE for solid modeling with distance fields
Halfspace is an experimental IDE designed for solid modeling using distance fields and the Fidget kernel. The project aims to simplify the creation of implicit surfaces by providing a more accessible interface for low-level geometric modeling.
Why it matters
It represents an evolution in CAD and 3D modeling tools, potentially lowering the barrier to entry for complex geometric design.

(The demo is best experienced on a computer; mobile Safari has some WebGPU issues, and pan / tilt / zoom interactions are not yet designed for multitouch)
Halfspace is a showcase app for the Fidget kernel , which is used for rasterization and meshing. Within the GUI, images are rasterized in real(ish)-time; models can be exported as either images or triangle meshes:
Since it's 2026, let me note at the outset that this is not vibe-coded . I've been working on it since April 2025 and am writing the code using my human brain, for various reasons (and Fidget dates back to 2022 ).
Now, the rest of this writeup assumes some knowledge of implicit surfaces; please see many previous writeups for details for more background info (or just keep reading, you'll be fine).
