Abstract

A method to accurately create a multi-image mark-making tool so as to simulate digitally the rendering of a printed articulation, stroke, or mark of a donor natural medium used in graphic arts, such paints, pencils, erasers, or other implements. Using a computer or other hardware the method provides a digital representation of multiple-image elements to simulate an implement tip, receptor grain and variable grain penetration, and smooth and continuous brush stroke without visible artifacts. The method allows for isolating a plurality of image elements, masking the image elements, creating a grid of image elements to function as an index of an array of the image elements, creating a file of such image elements for the purpose of accurately simulating brushes and other donor-receptor articulations common to natural media, and for rendering a brush stroke in multiple-images to accurately simulate digitally paint brushes and other implements.
