Abstract
We propose a method for automatically generating watercolor-style perspective drawings from three-dimensional geometric models. The method would be useful in the architectural-design area. It employs several technical approaches that realize the following general features of real watercolor-style perspective drawings: the outlines and edges of objects are drawn, there is no overflow of watercolor in the coloring especially of buildings, another objects like botanical trees are rendered often in simplified drawing styles and transparent light colors are used in most cases.
