Results from finite-element-calculations are usually visualized by colored surface- and contour-line-plots or polygonal patches or simply displaced lines and grids. In computer graphics however more advanced techniques like texture-mapping and NURBS are well established and there exist efficient algorithms and implementations. We show that these techniques are not only easy to use, but form a very natural and efficient approach for visualization of higher order finite-element's solutions like in p- and h-p-version. Texture-mapping is useful for displaying vector-valued data, too.
