Particle Loader

Particle Loader is a loader in the UI HUB loaders collection. A Canvas 2D particle loader. Dots are seeded once on a fibonacci sphere (fib) and converted to polar coords; each frame a bump curve eases them from the equator shell up over the poles, then each dot is yaw/pitch-spun, perspective-projected (PERSPECTIVE 3.5 onto pv/(pv-z)) and painter-sorted by depth so nearer dots dra…

The component is driven by 10 documented props (width, height, dotColor, density, dotSize, speed and 4 more), so colours, intensity, timing and density can be tuned from the call site instead of being hard-coded.

Implementation notes: Canvas 2D; requestAnimationFrame loop; Pointer Capture API.
