| Abstract: | h –p–adaptive projection with respect to any prescribed threshold value for the visual error. This projection can then be processed
by various local rendering methods, e.g. color coding of data or isosurface extraction. Especially for color coding purposes
modern texture capabilities are used to directly render higher polynomial data by superposition of polynomial basis function
textures and final color look-up tables. Numerical experiments from CFD clearly demonstrate the applicability and efficiency
of our approach.
