1. 1. Boundary Representation Modeling from Point Clouds

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Oskar Aronsson; Julia Nyman; [2020]
   Nyckelord :Point Cloud; Photogrammetry; RANSAC; Modeling; Bridge Inspection; Boundary Representation; Punktmoln; Fotogrammetri; RANSAC; Modellering; Brobesiktning; BREP;

   Sammanfattning : Inspections of bridges are today performed ocularly by an inspector at arm’s lengths distance to evaluate damages and to assess its current condition. Ocular inspections often require specialized equipment to aid the inspector to reach all parts of the bridge. LÄS MER

3. 2. Collision detection using boundary representation, BREP

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Jonas Sandqvist; [2015]
   Nyckelord :BREP; Boundary representation; AgX; Collision detection; Jonas Sandqvist; Newton Raphson;

   Sammanfattning : This thesis treats how to generate collision information for multibody simulations in AgX Dynamicswhere the geometries are described with the data structure boundary representation, BREP. BREP is adata structure that contains the exact mathematical description of each individual surface. LÄS MER

4. 3. Collision detection for trimming curves and BREPs

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Alexander Östman; [2014]
   Nyckelord :Colission detection; NURBS; BREP;

   Sammanfattning : This report treats the implementation of collision detection algorithms for Boundary representations (BREPs) consisting of connected trimmed surfaces, mainly Non Uniform Rational Basis Spline (NURBS) surfaces. Using the OpenNurbs software package, complicated geometries created in CAD program Space Claim were imported to the physics engine AgX, where dynamic simulations were carried out. LÄS MER
