    • Interactive Cutting in Voxel-Based Objects. Application to Simulate Transurethral Resection of the Prostate 

      Joan-Arinyo, Robert; Vilaplana, Josep (The Eurographics Association, 2006)
      Simulating cutting processes of human tissue is an important feature in virtual reality systems for medical training and rehearsal. In this paper we present a method to simulate the cutting operation in voxel-based virtual ...

    • Expeditious Modelling of Virtual Urban Environments with Geospatial L-systems 

      Coelho, António; Bessa, Maximino; Sousa, A. Augusto de; Ferreira, F. Nunes (The Eurographics Association, 2006)
      This paper presents Geospatial L-systems, a new extension of L-systems that incorporates geospatial awareness, and shows an application of this new tool in the expeditious modelling of urban environments, integrated with ...

    • Data-driven Tetrahedral Mesh Subdivision 

      Rodríguez, Lyudmila; Navazo, Isabel; Vinacua, Álvar (The Eurographics Association, 2006)
      Given a tetrahedral mesh immersed in a voxel model, we present a method to refine the mesh to reduce the discrepancy between interpolated values based on either scheme at arbitrary locations. An advantage of the method ...
