Method and device for generating handwriting, computer device, and readable medium

A handwriting generation device configured to generate a track of a marker pen based on a handwritten stroke, the track of the marker pen comprises at least one track segment, and the handwriting generation device comprises a handwriting generation module, a first process module, a second process module, and a track generation module;

• the handwriting generation module is configured to acquire sampling points on a handwritten track and generate a handwritten track curve based on the sampling points, wherein the handwritten track is a track of a stroke segment in the handwritten stroke;
• the first process module is configured to determine an arc length τ between interpolation points based on a coefficient and a parameter of a brush, wherein the arc length τ is an arc length between two adjacent interpolation points on the handwritten track curve;
• the second process module is configured to determine positions of the interpolation points on the handwritten track curve according to the arc length τ between interpolation points;
• and
• the track generation module is configured to overlay 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,
• the second process module is further configured to:
• for each interpolation point, calculate a t-value of each interpolation point on the handwritten track curve by using an iterative algorithm, wherein t is a parameter proportion of a Bezier curve, an approximate arc length L(tj+1) on the handwritten track curve corresponding to an iterative value tj+1 of the t-value converges with respect to an arc length S from the interpolation point to a first sampling point on the handwritten track curve, and the arc length S is a multiple of the arc length τ between interpolation points;
• and
• determine the positions of the interpolation points on the handwritten track curve by using the Bezier curve algorithm according to the t-values for the interpolation points on the handwritten track curve.
