Summary on Grant Application Form |
|
Most graphics programming languages use procedural implementation techniques; if one instruction is placed out of sequence then the image can be corrupted. Declarative approaches, such as object orientation, logics and functional programming, provide attractive alternatives. Images can be built in a declarative style without referring to low level sequences of instructions. Unfortunately, these approaches cannot easily capture the procedural information that is necessary to represent changes in images during interactive dialogues. Programmers must rely upon arbitrary features of implementation environments, such as assert and retract or pipeline objects. We will demonstrate that the explicit representation of temporal information and structured, part-whole hierarchies can be used to avoid these problems. The innovative task is to identify appropriate vocabularies for the graphical structures and temporal primitives that support general purpose, declarative, graphics programming languages.
