“…Interactive performance can be achieved for very large scenes on an NVIDIA GeForce 6800 GT (see Figure 1). Mesh levels of detail are produced using mesh simplification with additional vertex attributes [Garland and Heckbert 1998] for skinning weights, displacement corrections, PRT coefficients, etc. (see Figure 14).…”

We extend approaches for skinning characters to the general setting of skinning deformable mesh animations. We provide an automatic algorithm for generating progressive skinning approximations, that is particularly efficient for pseudo-articulated motions. Our contributions include the use of nonparametric mean shift clustering of high-dimensional mesh rotation sequences to automatically identify statistically relevant bones, and robust least squares methods to determine bone transformations, bone-vertex influence sets, and vertex weight values. We use a low-rank data reduction model defined in the undeformed mesh configuration to provide progressive convergence with a fixed number of bones. We show that the resulting skinned animations enable efficient hardware rendering, rest pose editing, and deformable collision detection. Finally, we present numerous examples where skins were automatically generated using a single set of parameter values.

“…The mesh adaptivity is determined during a top-down octree construction. Each sign change edge is shared by either four (uniform case) or three (adaptive case) cells, and one minimizer point is calculated for each of them by minimizing a predefined Quadratic Error Function (QEF) [19]: (13) where p i , n i represent the position and unit normal vectors of the intersection point respectively.…”

This paper describes a comprehensive approach to construct quality meshes for implicit solvation models of biomolecular structures starting from atomic resolution data in the Protein Data Bank (PDB). First, a smooth volumetric electron density map is constructed from atomic data using weighted Gaussian isotropic kernel functions and a two-level clustering technique. This enables the selection of a smooth implicit solvation surface approximation to the Lee-Richards molecular surface. Next, a modified dual contouring method is used to extract triangular meshes for the surface, and tetrahedral meshes for the volume inside or outside the molecule within a bounding sphere/box of influence. Finally, geometric flow techniques are used to improve the surface and volume mesh quality. Several examples are presented, including generated meshes for biomolecules that have been successfully used in finite element simulations involving solvation energetics and binding rate constants.

“…Early work on the simplification of polygonal models was focused on reducing the complexity of geometry alone [1,2], while later work also considered additional attributes such as colors, normals, and texture coordinates [3,4]. The first progressive encoding [5] allowed for a model's full resolution to be progressively reconstructed.…”

A virtual-world environment becomes a truly engaging platform when users have the ability to insert 3D content into the world. However, arbitrary 3D content is often not optimized for real-time rendering, limiting the ability of clients to display large scenes consisting of hundreds or thousands of objects. We present the design and implementation of an automatic, unsupervised conversion process that transforms 3D content into a format suitable for real-time rendering while minimizing loss of quality. The resulting progressive format includes a base mesh, allowing clients to quickly display the model, and a progressive portion for streaming additional detail as desired. Sirikata, an open virtual world platform, has processed over 700 models using this method.
