Prior art digital painting applications create strokes by repeatedly applying a stamp at incremental positions along a path. Such applications led to uniform marks being made by the mark making tool along the stroke as the same process as applied by the software application at each point along the stroke. However, some areas of a painting involve repetitive strokes, which can take a lot of time for the user. Embodiments of the invention provide the user with automated methods and systems that maintain a level of control the user seeks or needs whilst removing the repetitive nature of the area filling thereby saving the user time whilst delivering high quality results. The invention fills the area to be filled to painted with actual, individual strokes, offering the advantages of overlapping strokes and mixing paint for an increased 'natural' media look and feel. Additionally, the user is able to either specify parameters for the process in advance or to sculpt/tune the result as the software application paints.

Stroke tapestry systems and methods

The subject matter of this specification can be implemented in, among other things, a method to display a graphical user interface (GUI) of a graphics application, receive a selection of a first granular medium tool (GMT), receive a first input associated with the first GMT, the first input comprising one or more first input values characterizing placement of a first amount of a granular medium (GM) on a virtual drawing canvas, access one or more settings of the first GMT, determine, using the one or more first input values and the one or more settings, a first spatial distribution of the first amount of the GM on the virtual drawing canvas, and display, on the GUI, a first image corresponding to the first spatial distribution of the first amount of the GM.

Digital imaging of granular media in graphics applications

Stroke tapestry methods and systems

Graphic arts software has evolved to provide users with a variety of mark making tools to simulate different brushes, papers, and applied media such as ink, chalk, watercolour, spray paint and oils. However, in many instances the marks rendered appear unnatural and artificial despite the software's goal being to simulate as realistically. Accordingly, it would be beneficial to provide either users or the software application with a mechanism to remove or reduce artifacts indicative of artificial generation, e.g. rapid transitions. Further, in many instances the graphic images generated and/or manipulated refer to imagined environments or have elements that are physical in nature. Accordingly, it would be beneficial to provide users with a range of mark making tools that represent marks made by mark making tools comprising multiple elements following physical laws.
