3D graph tools
Five focused tools instead of one crowded menu. Each one opens the calculator in the mode its job needs, and every result stays in your browser.
3D Surface Plotter
Start from a blank z = f(x, y) surface, set the window, and export a PNG or a share link.
Parametric Surface Examples
See the (u, v) equations for a torus, helicoid and Möbius strip, with a related preview surface in the widget.
Vector Field Examples
Compare radial, sink, swirl and updraft fields as magnitude surfaces, with the divergence picture in words.
Embed Builder
Choose the frame size, theme, rotation and teacher mode, then copy an iframe that fits an LMS or a blog column.
Worksheet Export
Turn a graph into a worksheet asset: export a PNG, copy the formula and its LaTeX, and reuse the teaching question.
Need a graph produced for you?
For lessons, articles and course pages, the custom graph service builds fixed-scope embed sets.
