This paper proposes a speeding-up line-brush algorithm, which is based on the conventional Bresenham algorithm and draws on the conceptions of the auto-adaptive step straight-line algorithm, with the property that wide lines will be rendered straightforward by the plotter with a y-monotone.

Based on the features of body shoulder, this paper analyzes three factors that affect the design of garment shoulder framework ---shoulder width, shoulder pitch and shape of shoulder line, studies the relati-onship between shoulder framework, neckline and armhole, and discusses the problems in the design of shoulder framework and the corresponding causes.
