  1. 1. Real-time Terrain Deformation with Isosurface Algorithms

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Olle Nässén; Edvard Leiborn; [2019]
    Nyckelord :Isosurface; Marching Cubes; Terrain Deformation; OpenGL; Compute Shader;

    Sammanfattning : Background. Being able to modify virtual environments can create immersive experiences for video-game players. Storing data as volumetric scalar fields allows for highly modifiable 3D environments that can be converted into GPU-friendly triangles with isosurface algorithms. LÄS MER

  3. 2. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Bona Ryan; [2017]
    Nyckelord :Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Sammanfattning : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. LÄS MER

  4. 3. Estimating area of vector polygons on spherical and ellipsoidal earth models with application in estimating regional carbon flows

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Huiting Huang; [2017]
    Nyckelord :spherical ellipsoidal earth model; regional carbon flows; map projection; area of a polygon; atmospheric inversions; Earth and Environmental Sciences;

    Sammanfattning : Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. LÄS MER

  5. 4. Realtime Virtual 3D Image of Kidney Using Pre-Operative CT Image for Geometry and Realtime US-Image for Tracking

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Sebastian Ärleryd; [2014]
    Nyckelord :computer vision; computed tomography; ultrasonography; visualisation; real time; interactive; segmentation; SURF; RANSAC;

    Sammanfattning : In this thesis a method is presented to provide a 3D visualization of the human kidney and surrounding tissue during kidney surgery. The method takes advantage of the high detail of 3D X-Ray Computed Tomography (CT) and the high time resolution of Ultrasonography (US). LÄS MER

  7. 5. Fast and Adaptive Polygon Conversion By Means Of Sparse Volumes

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Mihai Aldén; [2011]
    Nyckelord :;

    Sammanfattning : This thesis describes the implementation of sparse volume conversion methods as used in movie production. The work consists of three different projects that are closely related. The first project presents the implementation of a signed distance field converter for polygonal models that can handle self-intersection meshes and non-manifold surfaces. LÄS MER
