FLAT is a method that directly decodes explicit triangle splats from compressed video diffusion latents in a single forward pass, improving geometric accuracy while enabling fast rasterization and physics-based interaction.
FLAT proposes a method to decode explicit triangle splats directly from video diffusion latents for geometrically accurate 3D scene generation. It introduces a ray-centered rotation parameterization and a product window function to improve gradient flow, achieving better geometric accuracy than prior feedforward methods while supporting real-time rendering.
