In this video I walk the process of making an object point it's (aim) axis to another object and how to control the up axis. Similar to what a aim constraint node does, but using only math operations with the Maya Pyhton API.
With the process described in the video should be quite straightforward to make your own DG aim node.
Hey guys , in this tutorial I am going to show you how to build a basic pose reader with maya nodes , if you dont know what a pose reader is check : comet-cartoons.com/maya.html

While working on my rig for Judd Simantov's Facial Rigging CGSociety workshop, I whipped up a tool to copy and paste set driven keys--greatly reducing the amount of work it takes to get the face shapes and poses for both sides of the face.
This is a three parter. . . a trilogy if you will (I love it when people say, "if you will"), about the basics of setting up an IK/FK snapping script that will correctly position your IK control and pole vector based on the rotations of your FK arm. A little bit of math, some elbow grease and a winning attitude are you need! And some python scripting. And some secret nodes. And a bunch of other stuff too. . .
Part 1 - covers the basics of what it is, why we'd bother and some basics of vector math that we'll need.
Part 2 - covers the hows and whys of writing the basic version of the python script.
Part 3 - covers using funky, cool message attributes to enhance the functionality of the script, etc.
