ResZLABS
The ResZ crystal RZ mark standing on a dark horizon. A white beam enters the Z and splits into a spectrum of six colours.

ResZ Labs

Light, computed exactly.

We build Natrix, a rendering engine that computes every pixel with exact arithmetic, and Lumen, the calm tower-defense game that runs on it.

Our work

Lumen's glass spire splitting white light into six coloured beams over still water.

The game

Lumen

A calm idle tower defense: one glass spire splits white light into six beams that hold back the drifting orbs.

Explore Lumen
A busy moment in Lumen: beams link crystal lenses while orbs burst into particles, all drawn by Natrix.

The engine

Natrix

A renderer that draws solid geometry with exact integer math and checks every frame against an exact reference.

The studio

ResZ Labs builds software where speed comes from mathematics, not from bigger hardware. Our engine, Natrix, renders by exact arithmetic and checks its own work; our first game, Lumen, is the proof that precise can also be beautiful.
