Digital imaging of granular media in graphics applications

A method comprising:

• establishing by a graphics application in execution upon a processing device of a computing device a set of spatial distributions of a first amount of a granular medium applied to a virtual drawing canvas rendered within a graphical user interface (GUI) of the graphics application by a granular medium tool by a user of the graphics application;
• wherein
• the granular medium comprises at least one of particulate matter and granular matter;
• one or more settings of the granular medium tool relate to properties of the at least one of particulate matter and granular matter within the granular medium;
• and
• the set of spatial distributions comprises:
• a first spatial distribution of the least one of particulate matter and granular matter within a portion of a first amount of the granular medium placed on the virtual drawing canvas that is fixed to the virtual drawing canvas;
• and
• a second spatial distribution of the at least one of particulate matter and granular matter within a remainder of the first amount of the granular medium placed on the virtual drawing canvas that is not fixed to the virtual drawing canvas;
• and
• the portion of the first amount of the granular medium placed on the virtual drawing canvas that is fixed to the virtual drawing canvas is determined in dependence upon at least of:
• a degree of friction of the at least one of particulate matter and granular matter within the granular medium and the virtual drawing canvas;
• and
• a degree of adhesion of the at least one of particulate matter and granular matter within the granular medium and the virtual drawing canvas.
