  1. 1. Analysis of Mutable Game Environments Built on a Tetrahedral Mesh : Tetras, a Potential Alternative to Voxels

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

    Author : Noah Tell; [2023]
    Keywords : Voxels; Tetrahedron; Tetrahedral Mesh; Tetrahedralization; Tessellation; Mutable Environment; Editable Terrain; Deformable Environment; Boolean Operations; Real-Time; Computer Games; Computational Geometry; Voxlar; Tetrahedror; Tetrahedralisering; Tessellering; Formbar Terräng; Booliska Operationer; Realtid; Datorspel; Beräkningsgeometri;

    Abstract : Historically 3D game environments have almost always been immutable. Mutable environments are a technical challenge that will affect performance. For games of the future to continue approaching realism, mutable environments are an essential step. READ MORE

  3. 2. Selection Intent Prediction in Online Virtual Environments : A Comparison Study

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

    Author : Charles-Eole Marichal; [2022]
    Keywords : HCI; XR; Selection; Prediction; Online virtual environments; MDI; XR; Urval; Förutsägelse; Virtuella online-miljöer;

    Abstract : In this work, we address the problem of the selection of 3D objects based on the user’s intent to interact with them in online virtual environments, both on desktop and VR devices. In addition to the traditional ray-casting technique, we select four promising techniques from the literature using time-dependent volumetric scoring (IntenSelect), trajectory prediction (KEP), Kalman filters enhancement (KalmanKEP) and machine learning with decision trees (MTP).

  4. 3. Volume Raycasting Performance Using DirectCompute

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Håkan Johansson; [2012]
    Keywords : volume rendering; volume raycasting; directcompute; directx11; performance;

    Abstract : Volume rendering is quite an old concept of representing images, dating back to the 1980's. It is very useful in the medical field for visualizing the results of a computer tomography (CT) and magnet resonance tomography (MRT) in 3D. READ MORE

  5. 4. Out-of-Core Multi-Resolution Volume Rendering of Large Data Sets

    University essay from Medie- och Informationsteknik

    Author : Fredrik Lundell; [2011]
    Keywords : out-of-core; volume rendering; raycasting; large datasets; gpgpu; streaming; multi-resolution; openCL; bricking; blocking; adaptive; intrablock interpolation; voreen;

    Abstract : A modality device can today capture high resolution volumetric data sets and as the data resolutions increase so does the challenges of processing volumetric data through a visualization pipeline. Standard volume rendering pipelines often use a graphic processing unit (GPU) to accelerate rendering performance by taking beneficial use of the parallel architecture on such devices. READ MORE

  6. 5. Large fused GPU volume rendering

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Stefan Lindholm; [2008]
    Keywords : ;

    Abstract : This master thesis describes the underlying theory and implementation of a fused GPU volume rendering pipeline. The open source framework of XIP, largely developed at Siemens Corporate Research, is extended with fusion capabilities through a Binary Space Partitioning approach. READ MORE
