  1. 1. Techniques for Fast and High-Quality 3D Reconstruction of General Scenes

    Author : Sverker Rasmuson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; 3D reconstruction; computer vision; computer graphics; volumetric video;

    Abstract : This thesis is a collection of techniques used for 3D reconstruction; the creation of 3D models from real world objects or scenes. Given the increase in accuracy, robustness and speed of modern methods and algorithms, new and exciting applications of this technology is constantly appearing. READ MORE

  2. 2. Perspective Correct Hand-held Augmented Reality for Improved Graphics and Interaction

    Author : Ali Samini; Karljohan Lundin Palmerius; Lucio Tommaso De Paolis; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With Augmented Reality, also termed AR, a view of the real world is augmented by superimposing computer-generated graphics, thereby enriching or enhancing the perception of the reality. Today, lots of applications benefit from AR in different areas, such as education, medicine, navigation, construction, gaming, and multiple other areas, using primarily head-mounted AR displays and AR on hand-held smart devices.

  3. 3. Improved Algorithms for Fast Shading and Lighting

    Author : Anders Hast; Ewert Bengtsson; Jos Stam; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Graphics; Datavetenskap; Computer science; Datavetenskap;

    Abstract : Shading is a technique that is used in computer graphics to make faceted objects appear smooth and more realistic. In the research presented in this thesis we have investigated how shading can be generated as efficiently as possible without sacrificing quality. READ MORE

  4. 4. How to Convert Reality into Virtual Reality: Exploring Colour Appearance in Digital Models

    Author : Beata Stahre Wästberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; light; virtual environments; interaction; Virtual Reality; colour appearance; visual appearance;

    Abstract : Today, the different actors in the design process have communication difficulties for visualizing and predicting how the not yet built environment is going to be experienced. Realistic virtual environments could make it easier for architects, users and clients to participate in the planning process. READ MORE

  5. 5. Sparse Voxel DAGs

    Author : Viktor Kämpe; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geometry; Shadows; Data structures; Tree; Visibility; Grid; Voxel; Directed acyclic graph; Computer graphics;

    Abstract : This thesis investigates a memory-efficient representation of highly detailed geometry in 3D voxel grids. The memory consumption of a plain dense grid scales too fast as the resolution increases to be feasible at very high resolutions. READ MORE
