  1. 1. Evaluation of Performance and Image Quality for Voxel Cone Tracing

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Johannes Finn; [2022]
    Nyckelord :computer graphics; voxel cone tracing; voxel-based rendering;

    Sammanfattning : Voxel cone tracing (VCT) is a rendering method designed to approximate global illumination in a fast and efficient way. Global illumination means to render not only the direct lighting of a scene but also light from indirect sources, simulating how light in the real-world tend to bounce around and illuminate even the areas that are occluded from a direct light source.

  3. 2. Global Illumination on Modern GPUs

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Fan Zhang; [2022]
    Nyckelord :Global illumination; Monte Carlo path tracing; voxel cone tracing; GPU acceleration; CUDA; OpenGL;

    Sammanfattning : This thesis that implemented Monte Carlo path tracing and voxel cone tracing for global illumination on GPU compared the performance and visual result. The Monte Carlo path tracing algorithm is implemented in CUDA to do parallel computing on GPU and accelerate the computing speed. LÄS MER

  4. 3. Real Time Voxel Cone Tracing using Bilateral Filters and 3D Clipmaps

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

    Författare :Alexander Lingtorp; [2020]
    Nyckelord :;

    Sammanfattning : Global illumination is a collective term of photorealistic lighting in computer graphics. Computation of global illumination is expensive in terms of real- time applications such as computer games. LÄS MER

  5. 4. Cascaded Voxel Cone-Tracing Shadows : A Computational Performance Study

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Sjödahl Dan; [2019]
    Nyckelord :shadows; voxel cone-tracing; rendering; real-time;

    Sammanfattning : Background. Real-time shadows in 3D applications have for decades been implemented with a solution called Shadow Mapping or some variant of it. This is a solution that is easy to implement and has good computational performance, nevertheless it does suffer from some problems and limitations. LÄS MER

  7. 5. Comparing 3D-Clipmaps and Sparse Voxel Octrees for voxelbased cone tracing

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

    Författare :Tomas Möre; Gustav Schneider; [2018]
    Nyckelord :;

    Sammanfattning : Voxel based cone tracing is a promising approach to approximate globalillumination for real-time applications. This technique utilizes a voxelfield approximating the original scene to retrieve the necessary radi-ance information during sampling. The simplest approach to creat-ing a voxel field is to use a 3D texture. LÄS MER
