Experimentation has led to understanding of the geometric accuracy needed to transform floating-point representations into pleasing images. This success achieved has not generalized to other applications.
Visualization is one type of model simulation.
Others are computational fluid dynamics, computational electromagnetics, and finite element analysis. Much tedious, human intensive modification of geometry is still required to support these applications. This talk introduces two supporting concepts application-specific geometric tolerances, and incomplete or multiple model representations. This broader view has software architectural implications for geometry and graphic subsystems, as will be illustrated with examples from the aerospace industry. Instead, local adaptation processes adjust visual sensitivity as we glance around a scene to capture low-contrast details and textures.
