What it does
Runiter Graphing Calculator 3D plots mathematical equations, inequalities and coordinate data using several coordinate systems.
Runiter Graphing Calculator 3D plots implicit, explicit and parametric equations or imported coordinates in Cartesian, polar, cylindrical or spherical systems. For CSV, choose the graph type before import: 3D Cartesian reads the first three columns as x, y, z; other modes consider two to five columns. Comma, semicolon and tab separators are accepted. Invalid-number rows are skipped with a count warning, and detected grid data prompts confirmation. Scatter points can become a surface mesh, with image or .obj output. The product page lists up to ten million coordinates and 500-digit numerical precision. Version 10 retired Professional and made its features free; the download page currently lists 10.6 for 64-bit Windows, Mac and Linux. Older paid-edition restrictions should not be applied to that release.
