(EN) The invention relates to a model line drawing rendering method and device, and the method comprises the steps: carrying out the preprocessing of a concave line of a to-be-rendered model, and obtaininga preprocessing model, wherein the concave line is a line formed by the intersection of two surfaces, with an included angle smaller than a target angle, on the front surface of the to-be-rendered model; rendering a front model of the preprocessing model; deviating the vertexes on the preprocessing model to obtain a deviation model, and preprocessing operation enables the deviation model to forma concave line surface allowing rendering at the concave line; and rendering a reverse model of the offset model, the reverse model forming a model hook line of the front model on the front model. According to the invention, the technical problem that the hook line cannot be rendered on the concave surface of the model in the prior art is solved.
(ZH) 本申请涉及一种模型勾线的渲染方法和装置，其中，该方法包括：对待渲染模型的凹线执行预处理操作，得到预处理模型，其中，凹线是在待渲染模型的正面上夹角小于目标角度的两个面相交形成的线；渲染预处理模型的正面模型；对预处理模型上的顶点进行偏移，得到偏移模型，其中，预处理操作使得偏移模型在凹线处形成允许被渲染出的凹线面；渲染偏移模型的反面模型，其中，反面模型在正面模型上形成正面模型的模型勾线。本申请解决了相关技术中无法在模型上的凹面处渲染出勾线的技术问题。
