“…Lingua Graphica is a visual programming language for virtual environments [Stiles92]. Initial prototype versions of this language have been developed under the ITDM contract, but because customer emphasis was placed on responding to system evaluation, and we worked with finite resources, we put Lingua Graphic development on hold.…”

SUPPLEMENTARY NOTESAir Force Research Laboratory Technical Monitor: Dr. James Fleming, Brooks AFB, TX ABSTRACTThis research effort developed an immersed virtual environment for the instruction of orbital mechanics and Training Studio, a more general virtual environment instructional authoring system. Training Studio provides the instructor with the capability of developing instructional simulations and not needing a computer programmer to translate instructional objectives into code. It provides the instructor with a visual programming system that operates the virtual environment. In a Training Studio session, there can be several processes handling interaction and display of the virtual environment (Vista Viewer), several processes modeling the understanding of the participants (Training Assistant), and several processes controlling the simulation and visual aspect of individual objects (Agent Framework and Profiler). Suggestions for further evolution of this type of software are provided. There are a number of technologies developed or advanced under the ITDM contract which we feel contribute to an effective virtual environment for training. Foremost among these was the architecture approach using the virtual environment as a display server, and developing a network protocol that supports updating many such VE display servers. The philosophy behind this approach was to abstract the creation and use of distributed, multi-participant 3D spatial scenes in such a way as simplify instructional development, and yet still provide required flexibility. SUBJECT TERMSWith the Training Studio software, we have realized a software system in which it is possible to construct and deliver training scenarios in an immersed, interactive setting. The proposed final goal of an orbital mechanics demonst...

“…Less use has been made of 3D graphics as a medium for visual programming and visualisation, but some examples are Cube [6], Lingua Graphica [8], MAP [2], ToonTalk [5], SAM [3], the Cone Tree [7], and AMAZE 3D [1]. These show the potential for 3D notations.…”
