“…The first progressive encoding [5] allowed for a model's full resolution to be progressively reconstructed. However, textured models that are simplified with this method produce poor results, which led to simplification algorithms based on texture stretch [6,7]. Our work closely follows Sander, et al [7] with a few modifications (see Section 4), most importantly to allow the process to run unsupervised.…”

“…Instead, the system copies only the referenced parts of textures into the atlas. To do so, the mesh is first partitioned into charts, or contiguous groups of triangles in the mesh [7]. The system creates a chart for each triangle and a greedy algorithm merges adjacent charts that create the least additional error using a priority queue.…”

“…The system creates a chart for each triangle and a greedy algorithm merges adjacent charts that create the least additional error using a priority queue. The process closely follows the algorithm from Sander et al [7] and Garland et al [9], with a few modifications. First, merging identical but oppositefacing triangles is disallowed, so that double-sided geometry does not result in charts that cannot be parameterized into texture space (see Section 4.3).…”

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.

A hybrid level‐of‐detail representation for large‐scale urban scenes rendering

A novel hybrid level‐of‐detail (LOD) algorithm is introduced. We combine point‐based, line‐based, and splat‐based rendering to synthesize large‐scale urban city images. We first extract lines and points from the input and provide their simplification encoded in a data structure that allows for a quick and automatic LOD selection. A screen‐space projected area is used as the LOD selector. The algorithm selects lines for long‐distance views providing high contrast and fidelity of the building silhouettes. For medium‐distance views, points are added, and splats are used for close‐up views. Our implementation shows a 10 × speedup as compared with the ground truth models and is about four times faster than geometric LOD. The quality of the results is indistinguishable from the original as confirmed by a user study and two algorithmic metrics. Copyright © 2014 John Wiley & Sons, Ltd.

Mesh quadrangulation has received increasing attention in the past decade. While previous works have mostly focused on producing a high quality quad mesh of a single model, the connectivity of the quadrangulation is typically difficult to control and varies among models even with similar shapes. In this paper, we propose a novel interactive framework for quadrangulating a set of models collectively with compatible connectivity. Furthermore, we demonstrate its application to 3D mesh morphing. In our approach, the user interactively sketches a skeleton within each model, and our method automatically computes compatible base domains for all models from these skeletons, on which the models are parameterized. With this novel parameterization, it is very easy to generate a pleasing and smooth 3D morphing sequence among these compatible models. The method yields quadrangulation with comparable quality to existing approaches, but greatly simplifies compatible re-meshing among a group of topologically equivalent models, in particular characters and animals models, with direct applications in shape blending and morphing.
