The brush plays an important role in creating Chinese calligraphy. We regard a single bristle of a writing brush as an
elastic rod and the brush tuft absorbing ink as an elastic cone, which naturally deforms according to the force exerted on
it when painting on a paper, and the brush footprint is formed by the intersection region between the deformed tuft and
the paper plane. To efficiently generate brush strokes, this paper introduces interpolation and texture mapping approach
between two adjacent footprints, and automatically applies bristle-splitting texture to the stroke after long-time painting.
Experimental results demonstrate that our method is effective and reliable. Users can create realistic calligraphy in real
