| Abstract: | As an alternative surface representation, point-based geometry neither has to store nor to maintain globally consistent topological information. It can both process shape flexibly and render appearance efficiently of extremely complex 3D model, therefore it has experienced a major renaissance in recent years. A comprehensive survey of point-based computer graphics was proposed. After introducing the general framework of point-based technical, various up-to-date shape representations, geometric algorithms and rendering methods were reviewed evaluated, which used points as a universal graphics primitive. At last, some challenges together with the future directions of point-based computer graphics were indicated, and an extensive bibliography was also provided. |
