A tetraview is a visualization technique for bivariate complex functions. In the simplest case, the graph of a complex-valued function w=w(z) can be considered as a hypersurface in R^4 with four real coordinates (R[z],I[z],R[w(z)],I[w(z)]). Carrying out a rotation in four dimensions and projecting the first three coordinates into (ordinary) R^3 then allows the changes from (R[z],I[z],R[w(z)]) to (R[z],I[z],I[w(z)]) to (R[w(z)],I[w(z)],R[z]) to (R[w(z)],I[w(z)],I[z]) to be visualized continuously.
