Visualizing scalar fields represented by adaptive square triangulations

Regular grids representing volume data are usually preferred to triangulation structures because they are simpler to store and faster to process. We consider a special family of triangulations combining the flexibility of an adaptive representation of fields with some intrinsic regularity. We show that the projection algorithm to visualize scalar fields represented by adaptive square triangulations is far more efficient than to visualize general triangulations and it is competitive with regular grid visualization techniques.
