AI Analysis

●●●BangerRabbit HoleEye CandyWizardry

WebGPU renders millions of galaxies in-browser with real-time density correction filters.

Strengths
  • Implements volume-limited 1/V_max and Schechter LF corrections directly in the shader.
  • ACES tone mapping and Asinh curves provide cinematic control over cosmic web filaments.
  • Instant search and focus navigation handles massive datasets without server-side paging.
Weaknesses
  • Fails gracefully but uselessly on devices without WebGPU adapter support.
  • No export functionality to save specific views or share curated galaxy clusters.
