This script has been integrated into the “Extra Objects” Add-On already included into Blender.
Simply activate that script and you are good to go.
Add -> Extra Objects -> Math Function
Old Post content:
Had some time to play around with mesh creation code again.
This script lets the user create a (mesh) surface where the z coordinate is a function of the x and y coordinates.
z = f(x,y)
Link to the script
(Save the “Raw data blob” link there as a file into your .blender/scripts/addons/ directory)
You can then enable the plugin in the User Preferences under Add-Ons.
Direct download link to the most recent version (Blender2.5):
Once installed, the script is available from the Add Mesh -> 3D Function Surface menu.
