Paintbrush and Liquid Simulation

摘要

Paintbrush and liquid simulation techniques are described. In one or more implementations, input is received to perform brush strokes with a virtual paintbrush on a virtual canvas. For virtual paint on the virtual canvas, lifelike paint qualities are simulated. However, the lifelike paint qualities are simulated solely for the virtual paint that is within a region of the canvas. The lifelike paint qualities are not simulated for virtual paint located outside the region. As part of simulating the interaction between the virtual paint, the virtual paintbrush, and the virtual canvas, various parts of the simulation may be performed by different processing units. For example, bristles of the virtual paintbrush may be simulated utilizing a first processing device such as a central processing unit (CPU). A second processing unit, such as a graphics processing unit (GPU), may be employed to simulate the lifelike effects of the virtual paint.

主权项

1. In a virtual paint environment to simulate lifelike painting qualities, a method implemented by a computing device, the method comprising:
receiving input describing one or more brush strokes of a virtual paintbrush on a virtual canvas; and simulating, for virtual paint on the virtual canvas, one or more of the lifelike painting qualities within a region of the virtual canvas associated with the virtual paintbrush, the one or more lifelike painting qualities not being simulated for the virtual paint outside the region, and the one or more lifelike painting qualities being simulated based in part on interaction of the virtual paintbrush with the virtual paint according to the one or more brush strokes.
