I've been having a great time delving deeper into the Maya Python API (OpenMaya) recently. For the capstone project of my 3D Animation minor, I'm mock-developing a course called "Intro to Technical Art" using OpenMaya and Python to develop tools in Maya. As someone who has always enjoyed teaching, especially when it relates to computer graphics, this project has been really fulfilling for me.
These meshes are being manipulated with a custom paint deformer I wrote with OpenMaya and Python. It iterates through the vertices of each mesh and applies either a sine or cosine calculation to each, depending on what the user chooses.
This is just the first project in my hypothetical course, but there are many more to come.
