虚拟仪器中的科学计算可视化系统:介绍了虚拟仪器中科学计算可视化的特点和实现方法。通过软件适配器的方法和基于区域配置的策略,实现多区域、多显示模式的混合和自由切换显示,通过多次细化等方法,加速图形显示来满足虚拟仪器对图形显示实时性的要求。研制了一种通用的虚拟仪器科学计算可视化环境,给出了该可视化系统在典型虚拟仪器中的应用。关键词:虚拟仪器;科学计算可视化;软件适配器;区域配置;多次细化Abstract : The paper discussed the features of visualization in scientific computations which were used in the field of virtual inst rument s , and the implementation approaches. With the software adaptor and the strategy based on region configuring , complex display with multiple modes in multiple regions was realized , which can be switched f reely. In order to meet the demands in real - time graphics’display of virtualinst rument s , special methods such as zooming by degrees were adopted to accelerate graphics’display. A general - purpose environment for visualization in scientific computations of virtual inst rument was developed. Some applications of the techniques discussed above in some typical virtual inst rument s were presented at the end of the paper.Key words : virtual inst rument ; visualization in scientific computation ; software adaptor ; region con2figuring ; zooming by degrees
