Editor
StableLive GLSL raymarcher — the core lab.
WebGL2 · runs in your browser · no install
A signed distance field editor
that ships to Godot.
Author raymarched SDF scenes in a live GLSL editor with honest GPU metrics. Export as a working Godot 4 project, an STL mesh, a PNG, a WebM, or a standalone HTML page. Plus a suite of experiments — audio-reactive, genetic, neural, and more.
Requires a WebGL2-capable browser. Runs entirely client-side.
What the editor actually does
Live GLSL hot-swap with error remapping, orbit camera, soft shadows, ambient occlusion, tonemapping, volumetric fog, N-bounce reflections, subsurface scattering, dynamic resolution, PNG capture, WebM recording, standalone HTML export, marching-cubes STL export, and a one-click Godot 4 project export.
Export
One-click Godot 4 project
Your map() body ports verbatim into a .gdshader. You get main.tscn with a SubViewportContainer + SubViewport, an orbit camera, and an in-scene panel for blend radius, animate-time toggle, resolution scale, and max steps. Unzip, import in Godot, hit F5.
Honest metrics
Real GPU timer queries
Frame time is measured with EXT_disjoint_timer_query_webgl2 when the extension is available, and falls back to a requestAnimationFrame delta when it isn't. Per-pixel step counts are read back from the render target only when the cursor is hovering the canvas, because readPixels stalls the pipeline. gl.finish() is deliberately not used — it reported garbage.
Holds framerate
Rolling-median dynamic resolution
A 15-frame rolling median of frame time drives render-scale adjustments with a hysteresis dead zone and a cooldown between changes. Scene FBOs are bucketed to 64-pixel increments so the small per-step scale changes don't reallocate GPU memory every frame.
The modules
The editor is the core. Everything else is a self-contained experiment that reuses the raymarching engine for something specific. Some are polished, some are speculative — each card says which.
