Abstract:

This letter presents a 3-D Gaussian rendering processor that integrates a spherical beta (SB) illumination module with a mixed-precision rendering engine to enable energy-efficient novel-view synthesis on edge devices. SB replaces spherical harmonics (SH) with a hardware-efficient kernel implemented using a pipelined fixed-point piecewise linear (PWL) power unit. The pipeline …

Abstract:

The 3-D Gaussian splatting (3DGS), based on a machine learning-driven radiance field technique, is rapidly emerging as a next-generation solution in 3-D graphics. Owing to its short modeling time, computational simplicity, and high rendering quality, it is expected to replace traditional 3-D graphics on edge devices. However, its substantial memory …
