Abstract

Grammar-based procedural modelling on its own produces a larger space of generated models than is artistically desirable. Probabilistic sampling techniques can help search this result space for models that best fit a set of constraints. We aim to provide a useful probabilistic search function that can be run at interactive rates to enable the short feedback loops artists require for incremental, exploratory design. We present a constraint for use in Sequential Monte Carlo optimization where artists draw curves to guide the generation of models. The high-level structure of models can be intuitively specified by our constraint framework, allowing for variation in low-level details to be automatically filled in. We present a real-time model editor to demonstrate the artistic utility of our method.
