Graphs approximate mathematical functions on finite grids. Discontinuities, singularities and very steep slopes may be omitted. Coordinates are dimensionless unless your model defines units.

Plot three-dimensional functions without installing software

PixelOkay 3D Mathematics Visualizer lets students, educators and researchers enter mathematical functions and inspect 3D surfaces, parametric forms and curves. Rotate and zoom plots, compare several equations, set custom domains and resolution, then export a PNG image, raw XYZ samples as CSV, an OBJ mesh or an editable JSON project. The expression evaluator accepts a restricted mathematical grammar, not JavaScript.

What this tool can and cannot do

Use explicit z=f(x,y) surfaces, parametric (x(u,v), y(u,v), z(u,v)) surfaces and (x(t), y(t), z(t)) curves. Complex-valued solutions and implicit surfaces are not supported. Meshes are sampled approximations, not symbolic proofs or engineering CAD. Projects save to your own browser storage only if you request it. Initial Three.js loading requires internet access to the pinned CDN; equations and project data are not uploaded.

Using 3D Mathematics Visualizer

Choose a surface or curve example, enter supported expressions and finite domains, then generate the plot. Use the numerical probe to inspect a coordinate, adjust the view and save editable JSON or sampled geometry.

Plots are numerical samples, not symbolic proof or guaranteed singularity detection. Limits include 10 plots, bounded domains and 500,000 exported samples. Implicit surfaces and complex coordinates are unsupported. Three.js 0.186.1 loads from jsDelivr for WebGL; the software canvas fallback differs in rendering quality. Equations are processed locally, while CDN requests expose ordinary connection metadata.

Choose a numerical plot, sampled geometry or editable setup

Project JSON: retain supported expressions, finite domains and plot settings.

OBJ or CSV: exchange sampled geometry or coordinates, not symbolic mathematics.

PNG: share a viewport picture.

Point probe: inspect a numerical coordinate within the chosen sampling/model limits.

Practice: inspect a simple explicit surface

Select an explicit-surface workflow and enter the supported expression x + y with a finite domain.

Generate the plot and compare selected coordinates with the numerical probe.

Save JSON before exporting a picture or samples.

This is an authored plotting exercise, not a symbolic proof or an observed renderer result.

3D plotting questions

Does a smooth plot prove continuity or find every singularity?

No. Rendering uses finite numerical samples. It does not provide symbolic proof or guaranteed singularity detection; sampling budgets and the chosen domain affect the view.

Can I plot implicit or complex-valued surfaces entirely offline?

Implicit surfaces and complex coordinates are unsupported. WebGL setup downloads the supplied Three.js modules from a CDN; the local software fallback differs in rendering quality.
