  1. 1. Comparison between Smoothed-Particle Hydrodynamics and Position Based Dynamics for real-time water simulation

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

    Författare :Rasmus Andersson; Erica Tjernell; [2023]
    Nyckelord :Fluid simulation; Lagrangian fluid simulation; Smoothed-Particle Hydronamics; Position Based Dynamics; Vätskesimulering; Lagransk vätskesimulering; Smoothed-Particle Hydronamics; Position Based Dynamics;

    Sammanfattning : Two of the methods common in video game fluid simulation are SmoothedParticle Hydrodynamics (SPH), and Position Based Dynamics (PBD). They are both Lagrangian methods of fluid simulation. SPH has been used for many years in offline simulations and has truthful visuals, but is not as stable as the newer method PBD when using larger timesteps. LÄS MER

  3. 2. Real-time Soft Body Simulation using Extended Position-Based Dynamics and Tetrahedral Deformation

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :William Kamnert; [2023]
    Nyckelord :Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

    Sammanfattning : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. LÄS MER

  4. 3. Informational AR-Overlay Development for Remote Air-Traffic Control

    Kandidat-uppsats, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Jonathan Söderlund; [2023]
    Nyckelord :Augmented-Reality; Air-traffic control; Camera Calibration; OpenGL.; Augumented Reality; Flygtraffikledning; Kamera kalibration; OpenGL.;

    Sammanfattning : Kontroll av trafik på och kring flygfält är ett krav för att få industrin och dess relaterade tjänster att upnå den säkerhet och effektivitet som krävs i dagens samhälle. Detta har traditionellt gjorts med bemannade kontrolltorn med full utsikt över fältet. Dessa torn är dock kostsamma både i konstruktion, drift och bemanning. LÄS MER

  5. 4. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

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

    Författare :Kyle William Coble; [2023]
    Nyckelord :Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Sammanfattning : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. LÄS MER

  7. 5. Motion Planning for Unmanned Aerial Vehicles

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

    Författare :Ossian Arn; Pontus Hagelin; [2023]
    Nyckelord :;

    Sammanfattning : This project presents a motion planning algorithm for an unmanned aerial vehicle (UAV).UAVs have become more popular in recent years because of their maneuverability. This has causedthe need for motion planning algorithms to increase. LÄS MER
