Key Features and Components

  • True Geometry For Lights- No more need for fake proxies. A more realistic simulation allows artists to create environments that approach photorealism. Lights with complex shapes, such as neon signs, work as they do in the real world.
  • Works as an Oracle for Shadow Rays - RTXDI tells the renderer where to send rays. Reducing the manual tuning required to light scenes will improve the efficiency of any art pipeline.
  • No More Hero Lights - Every light is a shadow caster. Scenes look richer and more grounded. Real-time renderings now reach the complexity level that only baked backgrounds previously allowed.
  • Built to be Paired with RTXGI - Can be combined with RTXGI for fast and scalable global illumination with many lights. RTXDI provides great results on its own, while amplifying the value of other NVIDIA ray tracing SDKs.
