In this paper scalar and vector data are visualised by suited colour scales based on perceptive and uniform colour models. Using opportune colour scales, colour information is created from the two-dimensional scalar data computed at different time steps. Direction and magnitude o...

In the paper, a new constructive approach to solving geometric constraints in 2D space is presented. The main step of the algorithm is pre-processing, which transforms both, geometric elements and geometric constraints, into simpler forms, and adds redundant constraints of distances and ...
