Using 3D Graphics in Combination with other Models of Computation

This paper presents a framework for developing a new graphics domain, called GRO, in Ptolemy II [1]. GRO is an OpenGL-based implementation that imports utilities, semantic and functionalities of OpenGL. The specification provides users to fully utilize the potential in the communication between the rendering engine and the computation in the model. This bottom-up design approach allows developers to create a event-based MoC that provides user, a sophisticated and exible specification. Based on OpenGL advantages, GRO is a user-friendly graphic domain that provides a declarative specification for the user to use. At the same time, it can also achieves better computation efficiency by migrating computation from the model (CPU) onto GPU’s. Demos are provided showing the implementation of the new graphics domain.
