Components of the Museum of Pure Form
The Museum of Pure Form system is composed by a video subsystem of 3D projection and a haptic subsystem for force feed-back. The haptic subsystem reproduces the contact forces generated by the interaction with the digital model through a haptic interface, so that the user may perceive a replica of the forces generated during the contact on his/her hand, together with the virtual representation of the movements of his/her hand along the surface of the digital model.

The realization of the “Museum of Pure Form” will be addressed through the achievement of several operational minor goals.

The three-dimensional digital acquisition of sculptures will be performed by capturing the geometric features of a selected set of sculptures belonging to museums collection and thus constructing a solid model for each statue. At the end of such process, a virtual library of digital models will be created, comprising both ancient and modern pieces of art. Such virtual collection will be shared among the museums, participating in the project, by means of a customized computer network.

Some medioeval and contemporary sculptures from some relevant European museums have already been digitally acquired. The choice of two historical-artistic periods which are so different and distant is not accidental, but aims at showing that the MPF can be used for a deeper fruition of works of art belonging to different periods

The haptic paradigm of interaction will be defined from a psycho-cognitive point of view. The most suitable haptic rendering and collision detection algorithms will be selected for the interaction with virtual sculptures.

During the third year of the project, two exhibitions of the MPF system will be performed in sequence at CGAC museum (Centro Galego de Arte Contemporanea of Santiago de Compostela-Spain) for a period of five months and then at OPAE museum (Opera della Primaziale of Pisa-Italy) for other five months, where the MPF system will be finally left. A specific area of such museums will be used as the site of the “Museum of Pure Form”. Such area will have to accommodate the HI systems as well as a projector and a large screen, and thus must be properly instrumented.

A computer web-based network will be defined and implemented. Such network will allow partners CGAC and OPAE to share a common collection of digital models of sculptures. Each sculpture will have a haptic digital model as well as a visual one and a file describing the history and data describing it.

The experimentation of a complete interaction (by sight and touch) with digital sculptures will enlighten on the limits and challenges of force feedback systems in the fruition of digital art.
