Real Time Simulation of Phaco-emulsification for Cataract Surgery Training Abstract (2008)

C. Mendoza, I. Navazo (editors, Marco Agus, Enrico Gobbetti, Giovanni Pintore, Gianluigi Zanetti, ...

We present a real–time simulation of the phaco-emulsification task in a virtual reality training system for cataract surgery. Phaco–emulsification consists in breaking in small fragments and...

Exploring Virtual Prototypes Using Time-Critical Multiresolution Rendering (2007)

Enrico Gobbetti, Riccardo Scateni, Marco Agus

Abstract. We present an application of our time-critical multiresolution rendering algorithm to the visual and possibly collaborative exploration of large digital mock-ups. Our technique relies upon...

Computing and Visualization in Science manuscript No. (2007)

Marco Agus, Andrea Giachetti, Enrico Gobbetti, Gianluigi Zanetti, Antonio Zorcolo

(will be inserted by the editor) A multiprocessor decoupled system for the simulation of temporal bone surgery

Creating and Presenting Real and Artificial Visual Stimuli for the Neurophysiological Investigation of the Observation/Execution Matching System (2007)

Marco Agus, Fabio Bettio, Enrico Gobbetti

Abstract. Recent neurophysiological experiments have shown that the visual stimuli that trigger a particular kind of neurons located in the ventral premotor cortex of monkeys and humans are very...

Hardware-Accelerated Dynamic Volume Rendering for Real-Time Surgical Simulation (2004)

Marco Agus, Andrea Giachetti, Enrico Gobbetti, Gianluigi Zanetti, Antonio Zorcolo

We developed a direct volume rendering technique, that supports low latency real time visual feedback in parallel with physical simulation on commodity graphics platforms. In our approach, a fast...

Hierarchical higher order face cluster radiosity for global illumination walkthroughs of complex non-diffuse environments (2003)

Enrico Gobbetti, Leonardo Span, Marco Agus

We present an algorithm for simulating diffuse interreflection in scenes composed of highly tessellated objects. The method is a higher order extension of the face cluster radiosity technique. It...

Adaptive techniques for real–time haptic and visual simulation of bone dissection. submitted for publication (2003)

Marco Agus, Andrea Giachetti, Enrico Gobbetti, Gianluigi Zanetti, Antonio Zorcolo

Bone dissection is an important component of many surgical procedures. In this paper, we discuss adaptive techniques for providing real-time haptic and visual feedback during a virtual bone...

Hierarchical higher order face cluster radiosity for global illumination walkthroughs of complex non-diffuse environments (2003)

Enrico Gobbetti, Leonardo Spanò, Marco Agus

We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects with diffuse or moderately glossy reflectance. The solution method is a higher order...

Real-time haptic and visual simulation of bone dissection (2002)

Marco Agus, Andrea Giachetti, Enrico Gobbetti, Gianluigi Zanetti, Antonio Zorcolo

Bone dissection is an important component of many surgical procedures. In this paper, we discuss a haptic and visual simulation of a bone cutting burr, that it is being developed as a component of a...

Mastoidectomy simulation with combined visual and haptic feedback (2002)

Marco Agus, Andrea Giachetti, Enrico Gobbetti, Gianluigi Zanetti, Antonio Zorcolo, ...

Abstract. Mastoidectomy is one of the most common surgical procedures relating to the petrous bone. In this paper we describe our preliminary results in the realization of a virtual reality...
