# Spiral Galaxy

A launch-page star-field hero built end to end on vgpu: a compute pass flows 4,600 stars along the five spiral strokes of a "6", converges them from a scattered sky and runs a pointer-repel simulation; additive quads draw them into an HDR scene; a bloom, lens-flare and dirty-glass chain finishes with an ambient glow, vignette and ACES tone mapping. Drag to rotate, hover to scatter.
