We propose a number of X3D extensions to enable shadows in the virtual worlds. Our higher-level extensions are an easy way to request shadows independently of their implementation...
In this paper, we present a method for generating a texture for hiding a marker in augmented reality applications. The texture is generated by interpolating the neighbourhood of t...
This paper describes experiments relating to the perception of the roughness of simulated surfaces via the haptic and visual senses. Subjects used a magnitude estimation technique...
Recently, the number of applications developed for smartphones has dramatically increased; however, at the moment, applications having the purpose of creating and displaying 3D mo...
– The paper presents some experiences in developing a virtual environment using a videogame engine. It provides the details and the caveats met during development, with particula...
