摘　　要：针对传统B/S模式下数字绘画速度慢、计算机中央处理器负载高等问题,提出高效率的计算机虚拟交互数字绘画方案。利用梯度方向差分法初步提取输入线条直线特征并剔除,基于LSD直线检测法精确遍历搜索直线特征,对直线线条与曲线线条赋予不同光滑度值以优化线条光滑度。在Web GL交互前端支撑下直接调用计算机图形处理器,完成数字图形渲染。测试中,此方法最终实现了快速、精准、低负担的个性化绘图创作效果,提升了用户创作体验感。Aiming at the problems of slow digital painting speed and high CPU load in traditional B/S mode,an efficient digital painting scheme of virtual interactive computer is proposed.The gradient direction difference method is used to preliminarily extract and eliminate the line features of input lines,and LSD line detection method is used to accurately traverse and search for line features,and different smoothness values are given to line and curve lines to optimize line smoothness.With the support of Web GL interactive front end,the computer graphics processor is directly called to complete digital graphics rendering.In the test,this method finally realizes the personalized drawing creation effect of fast,accurate and low burden,and improves the user’s creation experience.
