1. Semantic UFOMap : Semantic Information in Octree Occupancy Maps
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Many autonomous robots operating in unknown and unstructured environments rely on building a dense 3D map of it during exploration. What tasks the robot can perform depends on the information stored in this map. READ MORE

2. Real-time Terrain Deformation with Isosurface Algorithms
University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskapAbstract : 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. READ MORE

3. Comparing 3D-Clipmaps and Sparse Voxel Octrees for voxelbased cone tracing
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

4. View-Dependent Collision Detection and Response Using Octrees
University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologierAbstract : Context. Collision is a basic necessity in most simulated environments, especially video games, which demand user interaction. Octrees are a way to divide the simulated environments into smaller, more manageable parts,and is a hierarchical tree-structure, where each node has eight children. READ MORE

5. Real-time screen space reflections and refractions using sparse voxel octrees
University essay from Lunds universitet/Institutionen för datavetenskapAbstract : This thesis explores the data structure known as sparse voxel octree and how it can improve the performance of real-time ray tracing. While ray tracing is an excellent way of producing realistic effects in computer graphics it is also very computationally heavy. READ MORE
