“…In order to overcome the problem, the authors have already developed a modeling system Do which is based on a verbal interface aiming at three-dimensional (3D) geometrical modeling for figures and scenes in computer graphics (CG) by a verbal instructions in natural language [Y. Kawai and Okada 1996]. If instructions by verbal interface in natural language become possible, physically handicapped persons also can model a 3D-CG geometry and a 2D scene.…”

The authors have developed a modeling system Do in three dimensional computer graphics (3D-CG) that, by verbal instructions in natural language, models geometrical shapes and renders the images. The former system is based on a step-by-step construction scheme using static instructions and a static display, that is, a static verbal instruction creates a static scene and an image. This staticbased system scheme has a critical limitation at the conversation stage between a user and the system. In this paper, the authors propose a dynamic instruction and dynamic display methods for the modeling system. First, the dynamic display enables users to watch the animation indicating the change between the previous geometries and the next geometries with smooth transition during the execution of an instruction from the user. Second, the dynamic instruction enables users to give the next instruction before the animation ends. For those purposes, two geometrical transformation methods by affine transformation: (a) with a common difference matrix, and (b) with a common ratio matrix, are introduced and studied to generate frames for the animation. The proposed methods are implemented and evaluated by some experiments. The changes between instructions are observed naturally by the common ratio matrix method.

In this paper, we define a novel 3D building and query algebra for reconstructing car crash scenes. In particular, a low-cost 3D tool based on such algebra is proposed in order to collect and manage the same data set that will be used in the investigation procedures. Once acquired the GPS coordinates of the involved vehicles and scenes details by means of appropriate measurement systems, our tool provides the 3D models of all the scene objects with a set of useful multimedia information and displays them on 3D maps. Preliminary results in the case of a motorway car crash scene are presented and discussed.

Nowadays Augmented Reality (AR) is an emerging technology that promises significant results in a variety of applications. Despite the great advances in computer graphics and multimedia technologies, there is still a lack in the definition and building of a complete 3D object management system, in order to efficiently store, manage and retrieve such objects. In this paper a novel data model and a building and querying language for 3D objects are presented. This preliminary environment has been properly designed to be sufficiently powerful for including the functionalities and characteristics of modern 3D description languages, such as X3D and Collada, and at same time provides a formalism for optimization aims. Several examples from real Italian Cultural Heritage sites are provided and preliminary results are commented and discussed, showing the main advantages of the proposed system for both creation and information retrieval goal
