Abstract

A paint simulation system described herein includes a brush component that outputs a three-dimensional computer-implemented model of an image editing tool. A paint component receives the three-dimensional computer-implemented model and generates a two-dimensional map corresponding to a footprint of the three-dimensional model with respect to a computer-implemented canvas, wherein resolution of the two-dimensional map is substantially similar to resolution of a paint map of the computer-implemented canvas.
