Selecting Objects

Today I’ll show how to use Maya’s API to select objects based on their type.

The first is the traversal type which tells the iterator how to walk over the hierarchy when doing its search. The second is a function set filter. Basically MItDag grabs each object as it traverses the scene hierarchy and checks if the object has the function set specified as the filter.

Here’s an example of how to use MItDag.
