Methods and apparatus for deformation of virtual brush marks via texture projection

A system, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory storing program instructions that when executed by the at least one processor to cause the at least one processor to perform:
• determining a pose of a stylus that is in contact with or in proximity of a tablet device;
• modeling the stylus as a virtual projector that projects painting or drawing media onto a virtual canvas;
• determining an image that would appear on the virtual canvas as projected by the virtual projector, said determining an image being dependent on the determined pose, said determining an image comprising projecting vertices in a plane of projection from a tip of the stylus to vertices comprising the determined image on the virtual canvas;
• producing a virtual brush mark on the virtual canvas using the determined image as a two-dimensional stamp;
• and
• storing data representing an image that includes the virtual brush mark.

A non-transitory, computer-readable storage medium storing program instructions that when executed on one or more computers cause the one or more computers to perform:

• determining a pose of a stylus that is in contact with or in proximity of a tablet device;
• modeling the stylus as a virtual projector that projects painting or drawing media onto a virtual canvas;
• determining an image that would appear on the virtual canvas as projected by the virtual projector, said determining an image being dependent on the determined pose, said determining an image comprising projecting vertices in a plane of projection from a tip of the stylus to vertices comprising the determined image on the virtual canvas;
• producing a virtual brush mark on the virtual canvas using the determined image as a two-dimensional stamp;
• and
• storing data representing an image that includes the virtual brush mark.
