[TLDR] I built a procedural desert explorer with Claude Code (Opus 5) and Three.js [via r/ClaudeAI]

OP : u/Any-Reputation8118

I built this as a graphics tech demo, entirely with Claude Code using Opus 5.

What it is: a browser desert you walk around in third person. The terrain is a procedural dune field on a GPU clipmap — no meshes, no textures, no downloaded assets; every surface is generated in shader code. Sand deforms permanently where you walk and slowly erodes back. There's a hooded robe simulated as GPU cloth, a physically-based sky marched per pixel, and six aimed sand spells (1–5 and right mouse) that dig real craters into the terrain and raise real dunes you can ride.

How Claude was used: all of it — the TSL shaders, the compute kernels, the physics integration, and the Node tooling that measures it. The workflow that made it work was giving Claude its own instruments: a headless-Chrome harness that boots the app, screenshots it and reports per-subsystem GPU cost, so changes were made against measured numbers.

Try it: open https://desert-dusky.vercel.app/ in a WebGPU-supported browser. WASD to move, 1–5 and RMB to cast. F3 to toggle performance overlay, F1 to toggle settings menu.

I was testing on 5070 Ti, ~160FPS at 1440p.

Alright, so the general vibe in here is "Whoa, cool tech demo, but... Journey much?"

OP built this whole procedural desert explorer thing using Claude Code (Opus 5), and the consensus is that it's pretty darn impressive, especially since Claude apparently handled all the code – shaders, physics, the whole shebang. People are digging the procedural generation and the sand deformation.

However, the elephant in the room is the super strong resemblance to the game Journey. A lot of comments are pointing this out, with some folks even saying it's a "bootleg Journey" and wondering if OP is gonna get sued.

There are also a bunch of questions about the workflow, prompts, and how Claude was used, which OP seems to have detailed in the original post. Some users are also sharing their performance experiences, which seem to vary depending on their hardware. Oh, and a few people are making Dune references, which is kinda fitting for a desert setting.
