Colour graphics with three‐dimensional finite element meshes

The application of colour for an improved presentation of 3‐D structures with finite elements is reported. Also shown is how the hidden‐surface technique can be used for: (1) generating pictures in the hidden line alike mode, (2) generating photo‐alike pictures by shading the surfaces according to Lambert's cosine law, (3) showing the regions of different materials or properties by distinct colouring, (4) the presentation of temperature and stress fields by colouring. This colouring is done with smooth colour transitions and delivers pictures similar to those gained by thermography or stress optics. Furthermore, (5) it is possible to generate contour lines on the remaining visible surfaces. The problems arising with the attachment of a colour hardcopier are also considered.
