TC-GS: A Faster Gaussian Splatting Module Utilizing Tensor Cores
Contributions: โข Our detailed runtime analysis of the rendering pipeline proves that alpha computation in conditional alpha-blending is the performance bottleneck of the 3DGS inference rendering.
โข TC-GS is the first to expand Tensor Core applicability for 3DGS by mapping the alpha computation into matrix multiplication, enabling full utilization of otherwise idle TCUs in existing 3DGS implementations. As an algorithm-independent acceleration module, TC-GS seamlessly integrates into diverse 3DGS acceleration kernels and frameworks to achieve more efficient rendering performance.
โข We introduce a global-to-local coordinate transformation (G2L) that reduces the absolute magnitudes of quadratic coordinate terms, which are sensitive to Tensor Core half-precision computation. This enables lossless rendering quality while maintaining full acceleration benefits.
