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.
