WebApr 8, 2024 · However, they rely upon specialized volumetric rendering algorithms based on ray marching that are mismatched to the capabilities of widely deployed graphics hardware. This paper introduces a new NeRF representation based on textured polygons that can synthesize novel images efficiently with standard rendering pipelines. WebIn this work, we present an approach for LiDAR-based SLAM in Manhattan worlds that extracts planes from point clouds for registration and map creation. Contrary to most prior works in SLAM, our approach is designed with the task of motion planning in mind, as our geometric plane-based map representation enables fast and precise collision checking.
