With 3D sculpting, photogrammetry, and generative AI, geometric complexity has exploded, forcing game engines to adapt. RTX Mega Geometry is the key new technology that'll allow ray tracing to scale up and define the next generation of real-time image fidelity.

Watch the full replay of this GDC session to discover the new RTX Kit technology for accelerating cluster-based bounding volume hierarchy (BVH) building, along with its application to geometry streaming, dynamic tessellation and animation, as featured in Remedy's Alan Wake 2, and NVIDIA's Zorah and Dragon demos.
