We propose image-based point rendering (IBPR) for multiple range images from 3D scanners. Our approach is a natural extension of the method called pull-push so as to render scanned points with some measurement errors. Several extensions for rendering range images are proposed. One is a seamless rendering of a whole object even for points that have measurement errors. The other is a high quality rendering to reduce blurring. Our method is suitable for roughly checking the shape from range images.
Based on our basic IBPR approach, we also propose an interactive point-based painterly rendering algorithm. The interactive frame rate is achieved by using both a point-based approach to represent the geometry of the surface and an image-based approach for the rendering. Our algorithm achieves interactive rates and outperforms mesh-based previously reported results. A by-product of our work, we also provide a faster, higher quality IBPR algorithm. We have showed that using most sophisticated statistical approach, we could improve the rendering quality.
Moreover, our algorithm is familiar with various other image processing algorithms. As an example we demonstrate an interactive color-editing tool for points.
