This paper presents a synthesis method for 3D models using Petri net. Feature structure units from the example model are extracted
along with their constraints
through structure analysis
to create a new model using an inference method based on Petri net. Our method has two main advantages: first
3D model pieces are delineated as the feature structure units and Petri net is used to record their shape features and their constraints in order to outline the model
including extending and deforming operations; second
a construction space generating algorithm is presented to convert the curve drawn by the user into local shape controlling parameters
and the free form deformation (FFD) algorithm is used in the inference process to deform the feature structure units. Experimental results showed that the proposed method can create large-scale complex scenes or models and allow users to effectively control the model result.
