1. 11. Modeling and Visualization for Virtual Interaction with Medical Image Data

   Författare :Fredrik Nysjö; Ingela Nyström; Filip Malmberg; Ingrid Carlbom; Alexandru C. Telea; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image processing; volume rendering; haptic rendering; medical visualization; virtual surgery planning; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Interactive systems for exploring and analysing medical three dimensional (3D) volume image data using techniques such as stereoscopic rendering and haptics can lead to new workflows for virtual surgery planning. This includes the design of patient-specific surgical guides and plates for additive manufacturing (3D printing). LÄS MER

3. 12. Efficient Methods for Direct Volume Rendering of Large Data Sets

   Författare :Patric Ljung; Anders Ynnerman; Thomas Ertl; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Scientific Visualization; Medical Imaging; Volume Rendering; Raycasting; Transfer Functions; Level-of-detail; Fuzzy Classification; Virtual Autopsies; Computer science; Datavetenskap;

   Sammanfattning : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. LÄS MER

4. 13. Real-Time GPU Techniques for Advanced Lighting Phenomena

   Författare :Markus Billeter; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shading; Rendering; Participating Media; Volumetric Shadows; Mobile Graphics; Scattering; Computer Graphics; GPGPU; Many-Light;

   Sammanfattning : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. LÄS MER

5. 14. A Position Control-based Approach to Stiff Objects Haptic Rendering

   Författare :Yang Wang; Kjell Andersson; Lei Feng; Anders Robertsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; haptic rendering; position control-based approach; rigid-body interaction; Machine Design; Maskinkonstruktion;

   Sammanfattning : With electronic components and computational power becoming more portable and available to general consumers, applications like virtual reality (VR) and mixed reality (MR) are on the rise and renovating the industry of training simulators. Though it is not fully accepted in surgical robots, haptic force feedback can be safely introduced into various surgical training simulators to convey the necessary haptic cues needed to develop hand-eye coordination and motor skills.

7. 15. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

   Författare :Ola Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

   Sammanfattning : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.
