SPLASH: a hybrid 3D modeling/rendering approach mixing splats and meshes

Abstract

We propose a hybrid 3D modeling and rendering approach called SPLASH to combine the modeling flexibility and robustness of SPLAts together with the rendering simplicity and maturity of meSHes. Together with this novel SPLASH concept, we also propose a system turning a 3D point cloud, obtained for example through an SfM (Structure from Motion) approach, into a multi-textured hybrid 3D model whose shape is described by a triangle mesh plus a collection of elliptical splats.
