“…In our current implementation a limiting factor regarding performance is rendering speed. We use the purely software-based, high quality surface splatting renderer of Pointshop3D (see [Zwicker et al 2001]). Our experiments show that during deformation more than 50% of the total computation time are devoted to rendering, so we expect significant speed-ups if instead more efficient software renderers (e.g.…”

“…Point-based modeling techniques can directly handle this kind of input data without requiring extensive pre-processing. Additionally, recent progress in the efficient rendering of point-sampled surfaces [Zwicker et al 2001], [Rusinkiewicz and Levoy 2000], [Botsch et al 2002] demonstrates that point-based representations are well suited for interactive applications.…”

“…We use an extension of the surface splatting technique presented in [Zwicker et al 2001]. In this method, each sample point is represented by a surfel, an oriented elliptical splat that is projected onto the screen to reconstruct the surface in image space.…”

We present a versatile and complete free-form shape modeling framework for point-sampled geometry. By combining unstructured point clouds with the implicit surface definition of the moving least squares approximation, we obtain a hybrid geometry representation that allows us to exploit the advantages of implicit and parametric surface models. Based on this representation we introduce a shape modeling system that enables the designer to perform large constrained deformations as well as boolean operations on arbitrarily shaped objects. Due to minimum consistency requirements, point-sampled surfaces can easily be re-structured on the fly to support extreme geometric deformations during interactive editing. In addition, we show that strict topology control is possible and sharp features can be generated and preserved on point-sampled objects. We demonstrate the effectiveness of our system on a large set of input models, including noisy range scans, irregular point clouds, and sparsely as well as densely sampled models.

We present a novel 3D reconstruction system that can generate a stable triangle mesh using data from multiple RGB-D sensors in real time for dynamic scenes. The first part of the system uses moving least squares (MLS) point set surfaces to smooth and filter point clouds acquired from RGB-D sensors. The second part of the system generates triangle meshes from point clouds. The whole pipeline is executed on the GPU and is tailored to scale linearly with the size of the input data. Our contributions include changes to the MLS method for improving meshing, a fast triangle mesh generation method and GPU implementations of all parts of the pipeline.

Abstract. We present a novel point rendering primitive, called Differential Point (DP), that captures the local differential geometry in the vicinity of a sampled point. This is a more general point representation that, for the cost of a few additional bytes, packs much more information per point than the traditional point-based models. This information is used to efficiently render the surface as a collection of local neighborhoods. The advantages to this representation are manyfold: (1) it delivers a significant reduction in the number of point primitives that represent a surface (2) it achieves robust hardware accelerated per-pixel shading -even with no connectivity information (3) it offers a novel point-based simplification technique that has a convenient and intuitive interface for the user to efficiently resolve the speed versus quality tradeoff. The number of primitives being equal, DPs produce a much better quality of rendering than a pure splatbased approach. Visual appearances being similar, DPs are about two times faster and require about ± less disk space in comparison to splatting primitives.
