In this paper we present a systematic approach to create smoothly varying images from a pair of photographs to facilitate enhanced awareness of the depth structure of a given scene. Since our system does not rely on sophisticated display technologies such as stereoscopy or auto-stereoscopy for depth awareness, it (a) is inexpensive and widely accessible,(More)
Medicine is being benefited from the advances in Virtual Reality (VR) by uses of systems that permit greater level of detail in exams, simulation of procedures and in the teaching and training of professionals. In this paper is presented the AnatomI 3D, a medical atlas based in VR that presents interactive three-dimensional structures of the human body and(More)
Virtual Reality systems (VRS) allow the creation of immersive environments for realistic simulations of real life situations. Though this characteristic is quite important for the conception of medical applications, the addition of assessment tools make these applications more useful and efficient when used for training purposes. An assessment can either be(More)
We revisit the problem known as the visibility problem, for computing a potentially visible set of primitives, proposing a solution that can be used to accelerate the processing in real-time 3D visualization applications. We come up with a resulting dry structure in the sense of data reduction that can be used for on-line, interactive applications. Our main(More)
Cidade Universitária s/n – 58059-900 – João Pessoa – PB – Brazil *Aluno de Iniciação Científica financiado pelo CNPq. Abstract. The integration of data in a Virtual Reality System can depend on a Data Structure (DS) capable of making available the sharing of information between the routines of the system. This DS must be implemented in order to prevent(More)
