A technique for texture simplification driven by model simplification is also proposed. ...
In this paper we propose enhancements to 3D model simplification based on simplification envelopes (ESE) and curvature variations (CPD) on the surface of an object. ...
We also plan to integrate the simplification software to our past research on optimal bandwidth monitoring and develop strategies for efficient implementation over wireless networks.

We produce good simplification results by jointly processing mesh geometry and texture map to generate a unified saliency map for identifying visually important object features. ...
If texture maps are involved, it is common to let mesh geometry mainly model object shapes and use texture maps modelling most object details, optimising data size and complexity of an object. ...
Saliency-Driven Model Simplification Our method jointly considers features from 3D mesh and texture map for data reduction. ...

Generally, different simplification approaches are used to make 3D meshes viable for rendering. However, many of these approaches ignore vertex attributes for instanced 3D meshes. ...
In this paper, we implement and evaluate a simple and improved version to simplify instanced 3D textured models. ...
We produced two types of outputs: one an instanced 3D textured output and another an indexed 3D textured output carrying instance mesh information as a complete 3D mesh. ...

The technique, called Batched Dynamic Adaptive Meshes (BDAM) , is based on a paired tree structure: a tiled quadtree for texture data and a pair of bintrees of small triangular patches for the geometry ...
These small patches are TINs and are constructed and optimized off-line with high quality simplification and tristripping algorithms. ...
We employ an edge collapse simplification driven by the well known quadric error metric 7 with few minor modifications. ...

Multi-chart textures hinder the quality of the simplification of these techniques for two reasons: either the chart boundaries cannot be simplified leading to a lack of geometric fidelity; or texture distortions ...
For each collapse, the model is reparameterized by local bijective mappings to avoid texture distortions and chart boundary artefacts on the simplified mesh due to the geometry changes. ...
[LT00] introduced the image-driven simplification concept, where multiple images were used to decide which portions of a model have to be simplified. Sander et al. ...

The modification includes the simplification and the refinement of the triangle meshes as well as the animation of their vertices. ...
Because the presented approach is not only applicable to modification, but also to rendering, the triangle meshes have not to be converted into application specific representations such as simplification ...
