Abstract: The present disclosure provides a method for generating handwriting, belonging to the field of computer application technology. The handwriting generation method includes: acquiring sampling points on a handwritten track, and generating a handwritten track curve based on the sampling points wherein the handwritten track is a track of a stroke segment of a handwritten stroke; determining an arc length τ between interpolation points; determining positions of interpolation points on the handwritten track curve according to the arc length τ between interpolation points, where an arc length between two adjacent interpolation points on the handwritten track curve is the same as the arc length τ between interpolation points; and overlaying a handwriting effect parameter at the positions of the interpolation points to generate the track of the marker pen corresponding to the handwritten track curve.
