Geometry, speed, pressure, and anti-aliasing for ink rendering

摘要

Ink rendering techniques are described. In an implementation, an input is recognized by one or more modules that are executable on one or more processors of a computing device as an ink stroke to be rendered by a display device of the computing device. The ink stroke is built by the one or more modules using a strip of triangles and the strip of triangles is sent to a graphics processing unit to render the ink stroke.

主权项

1. A method comprising:
recognizing an input by one or more modules executable on one or more processors of a computing device as an ink stroke to be rendered by a display device of the computing device; building the ink stroke by the one or more modules using a strip of triangles; identifying, with a geometry module, a bend in the ink stroke that exceeds a threshold change of direction in the ink stroke; replacing, with the geometry module and in response to the identifying, the bend in the ink stroke with a stamp having a geometry of the bend; and sending the strip of triangles and the stamp to a graphics processing unit to render the ink stroke.
