Interactive Eulerian Neon Fluid Simulation

A reusable one-shot prompt shared by the author as the exact prompt used for the displayed GPU neon fluid simulator. The root post explicitly attributes the simulator to Opus 5.5. It requests a dependency-free, single-file WebGL fluid simulation with GPU FBO passes, neon dye interaction, ambient vortices, and a glassmorphism control HUD.

Prompt optimization tips

1

Specify editability

State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

2

Close the test loop

Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

3

Stage long builds

For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.

Imagine It. Shape It.
