  3. 2. Automatic Clustering of 3D Objects for Hierarchical Level-of-Detail

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Benjamin Wiberg; [2018]
    Keywords : hierarchical level-of-detail; mesh simplification; hierarchical clustering; 3D optimization;

    Abstract : This report describes an algorithm for computing 3D object hierarchies fit for hlod optimization. The algorithm is used as a pre-processing stage in an hlod pipeline that automatically optimizes 3D models containing multiple meshes. READ MORE

  4. 3. View-Dependent Collision Detection and Response Using Octrees

    University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Author : Albin Hermansson; [2016]
    Keywords : Collision; Octree; Pixel Area; Level-of-Detail; LoD;

    Abstract : Context. Collision is a basic necessity in most simulated environments, especially video games, which demand user interaction. Octrees are a way to divide the simulated environments into smaller, more manageable parts,and is a hierarchical tree-structure, where each node has eight children. READ MORE

  5. 4. Adaptive rendering of celestial bodies in WebGL

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Jonas Zeitler; [2015]
    Keywords : WebGL; Three.js; Javascript; HLOD; Geometry Clipmaps; Planet rendering; Level of Detail; Real-time rendering; Mobile devices; Heightmaps; Massive terrain; Out-of-core rendering; GPU programming; Astronomy; Visualization; Web Map Services; Datateknik; Datateknik;

    Abstract : This report covers theory and comparison of techniques for rendering massive scale 3D geospa- tial planet data in a web browser. It also presents implementation details of a few of these tech- niques in WebGL and Javascript, using the Three.js [1] 3D library. READ MORE
