Interactive visualization of flow fields
Allen Van Gelder, Jane P. Wilhelms · 1992
A technique to visualize S-dimensional flow fields int,eractively is described.The approach seems to represent the motion of the flow better than stat,ic images, and the motion is realtime even on low-t.o-mediumrange graphics workstations.It is part.icularlyappropriat,e for compressible fluid flows, as several features of such flows are represent.edsimultaneously: velocity, density, and energy.The met~hocl works on warped grids, which are common in comput.a.t.io~lal fluid dynamics simulations.The method may be appropriate for other visualization applications involving a combinat.ion of scalar and vector qualit.ies.To achieve interactive speeds for motion representation, two usually unrelated hardware capabilities are utilized: color interpolat,ion and discrete color mapping.
