Simulation of an erodible tip in a natural media drawing and/or painting simulation

摘要

A method, system, and computer-readable storage medium are disclosed for simulation of an erodible tip. A brush tool representing an erodible media is modeled as a height map. Information is collected about a user manipulation of a stylus representing a stroke made on a virtual canvas with the brush tool. A mark to be made on the virtual canvas is determined dependent on the brush tool model and the collected information. The determined mark is rendered. A change in the height map of the brush tool due to the stroke is determined dependent on the brush tool model and the collected information. One or more subsequent marks are rendered in response to manipulation of the brush tool dependent on the determined change in the height map.

1. A computer-implemented method to model a brush tool as an erodible input media, the method comprising:
modeling the brush tool as the erodible input media based at least in part on a stiffness parameter that represents a stiffness of the brush tool; determining a brush stroke on a virtual canvas dependent on the brush tool model and the stiffness parameter; determining a change in the brush tool model due to the brush stroke on the virtual canvas and the stiffness parameter.
