Fluid Cubes - GitHub Pages optimized (based on v0.4.5b debug influence heatmap)

What this is

• WebGL2 + Three.js instanced cubes driven by a GPU ping-pong simulation (MRT).
• Position/velocity live in floating point textures; a fullscreen shader updates them every frame.

What's new vs v0.4.1e

• Live bounding-box controls (X / Y / Z half-extents) via sliders.
  • Updates the visual wireframe container.
  • Updates the sim collision bounds (uBounds) immediately.
• Expanded force controls:
  • Flow Force (uForce): strength of the procedural vortex field.
  • Flow Scale (uFlowScale): spatial frequency of the flow field (higher = smoother; lower = more turbulent).
  • Stir Strength / Stir Radius: mouse/touch interaction strength + falloff radius.

Fixes in v0.4.3:

• Adds a soft inward 'wall repulsion' zone near the bounds to prevent corner sticking.
• Adds tangential damping on wall hits to reduce energy loss into corners.
• Adds tiny per-particle jitter to break perfect symmetry.

New in v0.4.4:

• Stronger, more obvious interaction (stir force scaling + defaults).
• Debug overlay toggle (button or 'D') that visualizes the interaction radius, falloff ring, and pointer velocity.

New in v0.4.5:

• Debug mode now also applies an in-scene cube heatmap based on interaction influence (radius falloff). This gives a direct visual correlation between Stir/Radius and what cubes are being affected.

Hotfix: Fix render shader compile by declaring uDebug uniform in fragment shader.

GitHub Pages (recommended)

• Upload these files to the repo root so index.html sits at /index.html.
• Settings -> Pages -> Deploy from branch -> main -> /(root).
