Occlusion Field

A moving Problem-red lamp casts long soft-edged shadows through a seeded field of dimensional blockers, snapping to the pointer while preserving the depth and falloff of each occlusion.

• Product moments
• Spatial storytelling
• Interactive identity systems

• Every blocker owns its own shadow vector and distance-based penumbra
• The lamp follows the pointer with the same coordinate system used by idle drift
• Seeded jitter avoids a sterile grid while preserving a stable composition
• Blockers and their shadows are capped by the shared compact particle budget
• Every control maps directly to this component's independent renderer contract
• Full-size and compact previews use the same implementation and behavior

Adaptive sampling, capped DPR and visibility-based suspension keep the renderer predictable. Test density on low-power mobile hardware before increasing it.

Pointer and touch coordinates are container-scoped; offscreen renderers stop work and pixel ratio is capped.

The visual canvas is decorative by default. Pair it with a semantic heading or description, and reduced motion holds a stable rendered frame.
