I wrote simple code for designing vector field and the resulted vector field from three design elements is :

Here is my simple tool to design vector field.Just move the mouse to a position (don’t click the mouse) and press a digital key such as 0 or 1 or 2 or 3 or 4 or 5 or 6 or 0 to assign the type of the design element. You can do this several times to generate several different design elements and finally press ‘F3’ key to update the vector field . You can also smooth the vector field by draging a curve with the mouse left button pressed followed by press ‘F2’ key,read readme.txt for more details.

Before run the program VFdesign.exe,you should first modify the filename “VFdesign.exe=postfix” to “VFdesign.exe”.

I have updated a new program VFDA.zip

A video of my “Design of 2D Time-Varying Vector Fields” is posted in youtube

The program is based on the following two papers (Thanks for the help from Guoning Chen). The source code is public available.
