GRAPH 3D v2.425 (20-FEB-2017)

[Han]

A slightly different approach.

Some screenshots of upcoming features.

The middle graph shows
\[f(x,y)= \sqrt{\frac{x}{\tan(.2y)}} - \cos(x) \]
Notice the handling of disconnected domains for the middle graph. Also, all three graphs feature an intersecting z-plane which can also be used to help users get the frame of reference when used at the bottom of the viewing box.

Other features to come include tracing the surface, as well as a mode-switch to toggle between z-clipping vs. translucent surfaces.
