A Graph-Based Language for Direct Manipulation of Procedural Models.

Kurzbeschreibung (Abstract)
Creating 3D content requires a lot of expert knowledge and is often a very time consuming task. Procedural modeling can simplify this process for several application domains. However, creating procedural descriptions is still a complicated task. Graph based visual programming languages can ease the creation workflow; however, direct manipulation of procedural 3D content rather than of a visual program is desirable as it resembles established techniques in 3D modeling. In this paper, we present a dataflow language that features novel contributions towards direct interactive manipulation of procedural 3D models: We eliminate the need to manually program loops (via implicit handling of nested repetitions), we introduce partial reevaluation strategies for efficient execution, and we show the integration of stateful external libraries (scene graphs) into the dataflow model of the proposed language.
