  1. 1. Optimizing Realistic 3D Facial Models for VR Avatars through Mesh Simplification

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Beiqian Liu; [2023]
    Nyckelord :Mesh Simplification; Virtual Reality; Realistic Avatars; 3D Face Reconstruction;

    Sammanfattning : The use of realistic 3D avatars in Virtual Reality (VR) has gained significant traction in applications such as telecommunication and gaming, offering immersive experiences and face-to-face interactions. However, standalone VR devices often face limitations in computational resources and real-time rendering requirements, necessitating the optimization of 3D models through mesh simplification to enhance performance and ensure a smooth user experience.

  3. 2. Rendering of Large Scale Continuous Terrain Using Mesh Shading Pipeline

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Martin Hedberg; [2022]
    Nyckelord :;

    Sammanfattning : Large open terrains require visual simplifications to be able to be rendered in real-time. One possibility is to subdivide the terrain into a quad tree where each node in the tree represents a simpler version of a tile of the terrain. LÄS MER

  4. 3. Evaluation of Error Metrics Used for Quality Assessment of Simplified Meshes

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Dennis Udd; [2022]
    Nyckelord :Level of Detail; Error Metric; Mesh Comparing; Mesh Simplification; 3D Optimisation; Computer Graphics; LOD;

    Sammanfattning : Level of Detail (LOD) is an important area in game development and it is a term used to describe the complexity of 3D models. Complex 3D models that are rendered from a far distance can often be simplified, to minimise rendering costs. The visual appearance of a simplified model should be as close to the original model as possible. LÄS MER

  5. 4. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    Master-uppsats, KTH/Fysik

    Författare :Yuer Zhao; [2021]
    Nyckelord :In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Sammanfattning : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). LÄS MER

  7. 5. Simplification of CAD Geometries to perform CEM Simulations

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Farrukh Bashir; [2021]
    Nyckelord :Defeaturing; Modification; Blending Features; FEA; CEM; CAD; CAE.;

    Sammanfattning : The purpose of this study is to investigate small features in CAD geometries which have high influence on computational time and memory consumption during electromagnetic simulations using CAE software. Computational Electromagnetics (CEM) simulations of complex CAD geometries like passenger cars crash often simulations remain incomplete due to a lot of irrelevant details. LÄS MER
