  1. 1. Compression of Sequential Voxel Data for Sequence-based Animation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Filip Antonijevic; [2023-10-23]
    Keywords : voxel; octree; grid; compression; animation; spatiotemporal; sorting; reordering; DXT; HSV;

    Abstract : This thesis presents a method for lossy compression of voxel data in an animation sequence. Uncompressed voxel animation can become very memory intensive and therefore need a more efficient method to store and render such data. READ MORE

  3. 2. Signed Distance Field For Deformable Terrain Shovel Collision Detection

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johannes Strid; [2023]
    Keywords : Signed Distance Fields; Collision Detection; Deformable Terrain;

    Abstract : One commonly used representation of complex objects in physics-based simulations are triangle meshes. This representation utilizes a collection of triangles to approximate an object. An alternative representation is a Signed Distance Field (SDF). READ MORE

  4. 3. A comparison of neuron touch detection algorithms utilising voxelization and the data structures octree, k-d tree and R-tree

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jonathan Gustaf Cilli; Karin De Verdier; [2023]
    Keywords : ;

    Abstract : Simulations of biologically detailed neuronal networks have become an essential tool in the study of the brain. An important step in the creation of these types of simulations is the detection of the connections between the nerve cells. This paper analyses the efficiency of four algorithms used for such purposes. READ MORE

  5. 4. Semantic UFOMap : Semantic Information in Octree Occupancy Maps

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Edvin von Platen; [2021]
    Keywords : Mapping; Octrees; RGB-D perception; Motion and path planning; Semantics; Robots.; Kartläggning; Octree; Färg- och djupperception; Rörelse- och vägplannering; Semantik; Robotar.;

    Abstract : Many autonomous robots operating in unknown and unstructured environments rely on building a dense 3D map of it during exploration. What tasks the robot can perform depends on the information stored in this map. READ MORE

  6. 5. Fusing Stereo Measurements into a Global 3D Representation

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

    Author : Per Blåwiik; [2021]
    Keywords : 3D Reconstruction; Stereo Reconstruction; Computer Vision; SDF; Octree; Marching Cubes;

    Abstract : The report describes the thesis project with the aim of fusing an arbitrary sequence of stereo measurements into a global 3D representation in real-time. The proposed method involves an octree-based signed distance function for representing the 3D environment, where the geomtric data is fused together using a cumulative weighted update function, and finally rendered by incremental mesh extraction using the marching cubes algorithm.
