Virtual reality framework for medical training: implementation of a deformation class using Java

Framework consists of software's construction technique which facilitates the reuse of analysis, design, code and tests. This article presents a proposal for objects-oriented Framework's construction for Virtual Reality (VR) applications on medical training, propitiating the most efficient and faster development of applications in this area. The initial approach is the applications breast's aspiration examination, where is necessary an object to represent the human organs and another one to simulate the necessary equipment to collect material. Functionalities like a collision's detection with accuracy, stereoscopy and deformation, were initially foreseen and already implemented for the framework construction. As medical training's tools, its importance is more emphasized, since it has reactions to the user's action. The deformation technique in three-dimensional objects was implemented in API Java 3D and its development based on Mass Spring's method, aiming at to supply a class to be used in medical training's tools.
