This test is about communication between Autodesk Maya and Rhino_Grasshopper.
UDP communications protocol can be used to share wathever data you need between the two platforms in realtime. This example send density values of a fluid system in Maya to Grasshopper.
Density values are sent from Maya with a custom script in Python. In Grasshopper we can use gHowl UDP receiver component to recive the data.
you can download the Python script and the Grasshopper definition here
# create the fluid in Maya and be sure that your fluid name is fluid1
# open the script editor and in Python tab load and run the script
# close the script editor
# open the Expression editor and write the expression: python("MayaFluidtoGh()");
# choose create and close Expression editor
# set fluid resolution the same of your fluid system in Maya
# (for 2D fluid systems Z value is 1)
# you need gHowl installed on your Grasshopper to run the definition
now play the animation in Maya
