Instanced model simplification using combined geometric and appearance-related metric [article]

Sadia Tariq, Anis Ur Rahman, Tahir Azim, Rehman Gull Khan
2021 arXiv   pre-print
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.  ...

In this paper, we present a real-time crowd rendering system on GPUs with a special focus on how to preserve texture appearance in progressive LOD-based mesh simplification algorithms.  ...  Our contributions are focused on a set of texture-preserving criteria for parallel and progressive mesh simplification.  ...  In the preprocess stage, we first split the original vertices based on the layout of texture coordinates in order to preserve the continuity of texture appearing on the surface.  ...

BDAM - Batched Dynamic Adaptive Meshes for High Performance Terrain Visualization

P. Cignoni, F. Ganovelli, E. Gobbetti, F. Marton, F. Ponchio, R. Scopigno
2003 Computer graphics forum (Print)  
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.  ...

Accurate Simplification of Multi-Chart Textured Models

N. Coll, T. Paradinas
2010 Computer graphics forum (Print)  
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.  ...

Efficient Representation of Triangle Meshes for Simultaneous Modification and Rendering [chapter]

Horst Birthelmer, Ingo Soetebier, Jörg Sahm
2003 Lecture Notes in Computer Science  
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  ...  The class representing the mesh is also template driven and uses the types of the vertex array and the type of the triangle array as template parameters.  ...
