In this paper, the visualization method of 3-D data field in volumetric-swept display system based on the helix rotation screen and Digital Micro-mirror Devices (DMD) is discussed. It often determines the degree to which the display is capable of accepting the parallel transfer of data and its potential for achieving a high voxel activation capacity. The more complexity the model, the more computing time and more pixels numbers that the generation method of helix slice may obtain on 2-D contour lines images. The superfaces algorithm that is one of the kinds of methods for simplifying polyhedral meshes is used to ensure that the images have good display shape approximation, decrease as far as possible for faces number of the model. Thus it can greatly reduce the storage capacity and the calculation speed in the 3-D display system.
