Ray-Traced Global Illumination (RTGI) represents one of the most significant leaps in computer graphics history. By 2026, it has transitioned from a niche hardware-stressing feature to the gold standard for visual fidelity in modern gaming and architectural visualization. Understanding RTGI: The Core Concept
Built directly into a game's engine (e.g., The Finals , Forza Motorsport , Metro Exodus ). It has access to the full 3D "world space" of the game, allowing it to calculate light bounces even from objects behind the player. Ray-Traced Global Illumination (RTGI) represents one of the
But within that broad term lies a specific technology that is arguably the most transformative visual leap of the decade: , or Ray Traced Global Illumination . or Ray Traced Global Illumination .
