Abstract:
Advances in 3D scanning technologies have enabled the practical creation of hundreds of millions of points. In this paper, we describe a novel image-based point rendering algorithm only using points. Most of previous point rendering algorithms has to prepare normal vectors in advance to establish shading effects. Our algorithm is based on image processing and can calculate normal vectors on the fly in each frame using principal component analysis. Also, our algorithm is familiar with various other image processing algorithms. As an example we demonstrate an interactive color-editing tool for points.
