New Method of Surface Reconstruction of Splat-Based Models

The surface splatting technique has several advantages in rendering models consisting of points, such as speed and quality of rendered images. After projecting all the splats on the plane of the image, it is necessary to reconstruct surfaces from several fragments generated in the previous step. Several heuristics make use of implicit information about the surface to determine which fragments constitute the same surface. In this work, a pre-processing performs the separation of surfaces by analyzing the normal vectors of the splats and their neighborhood relations. This step applies surface identifiers in splats in order to prevent fragments from different surfaces to be combined in the step of surface reconstruction.
