Free 3D Graphing Calculator
Plot 3D functions, surfaces, and classroom examples. Share or embed any graph in seconds.
Formula pages built for search and teaching
Each graph has a live widget, formula copy, LaTeX copy, PNG export, iframe embed, and teacher prompt.
Saddle Surface
z = x^2 - y^2A saddle surface curves up in one direction and down in the perpendicular direction.
surfaceGaussian Surface
z = exp(-(x^2 + y^2))A smooth bell-shaped surface centered at the origin.
surfaceElliptic Paraboloid
z = x^2 + y^2A bowl-shaped surface that opens upward.
surfaceInverted Paraboloid
z = 12 - x^2 - y^2A dome-shaped surface with a highest point at the center.
surfaceMonkey Saddle
z = x^3 - 3*x*y^2A three-way saddle with three valleys and three ridges.
surfaceSine Wave Surface
z = sin(x) + sin(y)Two perpendicular sine waves combined into one surface.
surfaceRipple Surface
z = sin(sqrt(x^2 + y^2))Circular waves radiate outward from the center.
surfaceDamped Ripple
z = sin(x^2 + y^2) / (1 + x^2 + y^2)A ripple surface whose waves fade away from the origin.
surfaceCone Surface
z = sqrt(x^2 + y^2)A circular cone rising from the origin.
surfacePlane
z = 2*x - y + 1A flat plane with constant slope.
surfaceTilted Wave Plane
z = 0.35*x + sin(y)A sloped plane with a wave running across it.
surfaceSine Cosine Product
z = sin(x) * cos(y)A checkerboard-like wave surface.
Tools for the distribution loop
The calculator is the function. The pages, embeds, and exports are the traffic machine.
3D Surface Plotter
Plot z=f(x,y), rotate the surface, export PNG, and copy an iframe embed.
Parametric Surface Plotter
Browse parametric examples and convert common surfaces into classroom-ready pages.
3D Vector Field Plotter
Use vector field examples as teaching pages for divergence, rotation, sinks, and sources.
Embed Builder
Tune iframe size, theme, controls, formula visibility, and locked view settings.
Worksheet Generator
Create printable graph prompts from selected examples using browser print.
Guides students actually search for
Short English pages answer the job to be done, then put the live graph directly beside the explanation.
Graph z=f(x,y)
Type a formula, choose x and y ranges, then rotate the result to inspect slices.
Saddle vs Minimum
A saddle curves up in one direction and down in another, unlike a true minimum.
Surface and Contours
Contours are horizontal slices of the 3D graph projected into 2D.
Teacher Setup
Use locked views, hidden formulas, and reveal prompts for classroom embeds.
Export PNG
Use the export button after rotating the graph to the desired angle.
Copy LaTeX
Copy the formula in LaTeX form for notes, worksheets, and articles.
Embed in Lesson
Copy the iframe code and paste it into a blog, LMS, or course page.
Sampling Density
Higher samples look smoother but require more browser work.
