Astheimer, P.P.AstheimerFelger, W.W.Felger2022-03-072022-03-071990https://publica.fraunhofer.de/handle/publica/286014An important data structure for visualization is the 3D scalar field and its graphical representation as a 3D transparent gaslike object. Besides discrete arbitrary scalar data e.g. from computer tomograms in medicine, there is a need to visualize continuous scalar data defined in algebraic functions e.g. electric potentials. Traditional volume visualization techniques work on latter fields in a very complicated way and with great overhead in computation and storage. Improvements are achieved by direct computation of transparency values with the mathematical theory of curve integrals.enmodeling of physical phenomenarenderingvisualisationvolume densities006report
