-Z Function Surface
-
-This script lets the user create a surface where the z coordinate
-is a function of the x and y coordinates.
-
- z = f(x,y)
-
-X,Y,Z Function Surface
-
-This script lets the user create a surface where the x, y and z
-coordinates are defiend by a function.
-
- x = f(u,v)
- y = f(u,v)
- z = f(u,v)
-
-Usage:
-You have to activated the script in the "Add-Ons" tab (user preferences).
-The functionality can then be accessed via the
-"Add Mesh" -> "Z Function Surface"
-and
-"Add Mesh" -> "X,Y,Z Function Surface"
-menu.
-
-Version history:
-v0.3.6 - Various updates to match current Blender API.
- Removed recall functionality.
- Better code for align_matrix
- Hopefully fixed bug where uMax was never reached. May cause other stuff.
-v0.3.5 - createFaces can now "Flip" faces and create fan/star like faces.
-v0.3.4 - Updated store_recall_properties, apply_object_align
- and create_mesh_object.
- Changed how recall data is stored.
-v0.3.3 - API change Mathutils -> mathutils (r557)
-v0.3.2 - Various fixes&streamlining by ideasman42/Campbell Barton.
- r544 Compile expressions for faster execution
- r544 Use operator reports for errors too
- r544 Avoid type checks by converting to a float, errors
- converting to a float are reported too.
- Fixed an error Campbell overlooked (appending tuples to an
- array, not single values) Thamnks for the report wild_doogy.
- Added 'description' field, updated 'wiki_url'.
- Made the script PEP8 compatible again.
-v0.3.1 - Use hidden "edit" property for "recall" operator.
- Bugfix: Z Function was mixing up div_x and div_y
-v0.3 - X,Y,Z Function Surface (by Ed Mackey & tuga3d).
- Renamed old function to "Z Function Surface".
- Align the geometry to the view if the user preference says so.
- Store recall properties in newly created object.
-v0.2.3 - Use bl_info for Add-On information.
-v0.2.2 - Fixed Add-On registration text.
-v0.2.1 - Fixed some new API stuff.
- Mainly we now have the register/unregister functions.
- Also the new() function for objects now accepts a mesh object.
- Changed the script so it can be managed from the "Add-Ons" tab
- in the user preferences.
- Added dummy "PLUGIN" icon.
- Corrected FSF address.
- Clean up of tooltips.
-v0.2 - Added security check for eval() function
- Check return value of eval() for complex numbers.
-v0.1.1 - Use 'CANCELLED' return value when failing.
- Updated web links.
-v0.1 - Initial revision.
