      Visualising in real-time high quality virtual environments, which are suitable for cultural heritage and virtual tourism, is often a challenging endeavour. This is primarily, due to the cost of rendering complex architectural ...
    • A Haptic Rendering Algorithm for Molecular Interaction 

      Stocks, Matthew B.; Laycock, Stephen D. (The Eurographics Association, 2008)
      Haptic rendering is the process of calculating and displaying physical forces to a user. Used concomitantly with a virtual environment it can further enhance a user's immersive experience whilst they interact with computer ...
    • Haptic Rendering of Complex Force Fields 

      Krenek, Ales (The Eurographics Association, 2003)
      With a particular focus in scientific applications, we propose a method of haptic rendering of virtual environments which require rather complex calculations to evaluate their behaviour. Therefore it is not possible to ...
    • Haptic Rendering of Dynamic Image Sequence Using String based Haptic Device SPIDAR 

      Jayasiri, Anusha; Akahane, Katsuhito; Sato, Makoto (The Eurographics Association, 2012)
      This paper concerns how to associate haptic signals with a dynamic image sequence or in other words a video to feel the haptic motion. Nowadays, there is a significant evolvement in haptic technologies and they are being ...
    • Haptic Rendering Techniques for the Interactive Exploration of CFD Datasets in Virtual Environments 

      Reimersdahl, T. van; Bley, F.; Kuhlen, T.; Bischof, C.H. (The Eurographics Association, 2003)
      In pure CFD visualization tools, some flow features are hard to visualize such as the properties of a local flow probe. Haptic rendering techniques offer an intuitive understanding and allow more detailed insights than the ...
    • Haptics-based Modelling of Pigmented Skin Lesions 

      Granados, Alejandro; Bryan, James; Abdalla, Taha; Osborne, Genevieve; Bello, Fernando (The Eurographics Association, 2015)
      Dermatology is under-represented in medical undergraduate education with newly graduated doctors not being able to identify common and important skin conditions. In order to become competent in diagnosing skin lesions, it ...
    • A Haptics-enabled Simulator for Transperineal Ultrasound-Guided Biopsy 

      Ritsos, Panagiotis D.; Edwards, Marc R.; Shergill, Iqbal S.; John, Nigel W. (The Eurographics Association, 2015)
      We present the development of a transperineal prostate biopsy, with high fidelity haptic feedback. We describe our current prototype, which is using physical props and a Geomagic Touch. In addition, we discuss a method for ...
    • Hardware Accelerated Visibility Preprocessing using Adaptive Sampling 

      Nirenstein, S.; Blake, E. (The Eurographics Association, 2004)
