移动设备上基于三维模型的线条画绘制

Stylistic Line Drawings of 3D Models on Mobile Devices

  • 摘要: 提出一种综合考虑移动设备客户端绘制能力和传输速度的混合型远程绘制方法.该方法采用渐进网格得到不同分辨率的细节层次模型,并利用渐进传输机制逐步传输数据,以缓解单次网络负载.服务器端可以根据网络质量状况、移动客户端的处理能力和用户交互请求来选择适宜的三维细节层次模型,提取特征轮廓线并将生成的线条集合传输给客户端进行本地风格化绘制.将该方法应用于考古数字博物馆展示中取得了良好的效果.

     

    Abstract: The paper proposes a hybrid remote rendering method which takes into account the balance between the graphic process ability and the transmission capability across network in the mobile client side. With mult-i resolution level of details with progressive meshes and progressive transmission scheme,the method can obtain a good balance between image quality and workload upon client-server sides.The server side can take the network bandwidth,limitations of mobile devices and user interactions into consideration, and then adaptively choose a model with proper LOD,extract the feature lines and finally send the line packages to client for local stylistic rendering.The method is applied to the archaeological digital museum for remote model display,and fine performance is obtained.
