This page is our tool to make a 3-D graph and STL file.
??Quadric Surface : Implicit Object
1) This tool can express implicitly defined quadric surfaces of the form and generate STL files.
** For more information on the Quadric Form, visit the link below:
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...".)
