  1. 1. 3D Modeling of Factory Scenarios for 5G Evaluations

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Haodong Zhao; [2023]
    Nyckelord :;

    Sammanfattning : 5G is a key enabler for a variety of use cases in smart manufacturing which requires communications with high reliability and low latency. In a dynamic industrial environment, objects such as machines, production lines, storage shelves, robotic arms, and automatically guided vehicles may cause fading and have a large impact on radio propagation.

  3. 2. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

    Författare :Zhenyu Li; [2023]
    Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

  4. 3. A Performance Comparison of Dynamic- and Inline Ray Tracing in DXR : An application in soft shadows

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Författare :Joakim Sjöberg; Filip Zachrisson; [2021]
    Nyckelord :dynamic ray tracing; inline ray tracing; hard shadows; soft shadows; rendering; dynamisk strålspårning; inline strålspårning; hårda skuggor; mjuka skuggor; rendering;

    Sammanfattning : Background. Ray tracing is a tool that can be used to increase the quality of the graphics in games. One application in graphics that ray tracing excels in is generating shadows because ray tracing can simulate how shadows are generated in real life more accurately than rasterization techniques can.

  5. 4. Real-time generation of kd-trees for ray tracing using DirectX 11

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Martin Säll; Fredrik Cronqvist; [2017]
    Nyckelord :Ray tracing; Kd-tree; acceleration; DirectX 11; compute shader;

    Sammanfattning : Context. Ray tracing has always been a simple but effective way to create a photorealistic scene but at a greater cost when expanding the scene. Recent improvements in GPU and CPU hardware have made ray tracing faster, making more complex scenes possible with the same amount of time needed to process the scene. LÄS MER

  7. 5. Hybrid Ray-Traced Reflections in Real-Time : in OpenGL 4.3

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Författare :Mattias Frid Kastrati; [2015]
    Nyckelord :rasterized ray-tracing; deferred shading; dynamic scenes; selective hybrid method;

    Sammanfattning : Context. Reaching photo realistic results when rendering 3D graphics in real-time is a hard computational task. Ray-tracing gives results close to this but is too expensive to be run at real-time frame rates. LÄS MER
