This page is our tool to make a 3-D graph and STL file.
3D-Parametric Surface
1) In general, parametric functions of three variables >can be visualized by our tool.
2) 3D Image and STL file
By using Sage, each component of an implicit function can be inputted and a resulting STL file can be obtained.
(You can save your STL file by clicking on the link at the bottom and selecting "Save file as...".)
