We are using Collada on our current project. The Maya exporter is
working great and the importer was straightforward to implement.
Collada accessors are flexible, but I wouldn't consider them to be
overkill. They are comparable in expressiveness to vertex declarations.
Here is an example:
<accessor source="#polySurfaceShape30-lib-Position-array" count="2864"
stride="3">
<param name="X" type="float"/>
<param name="Y" type="float"/>
<param name="Z" type="float"/>
</accessor>
The names are optional. They just serve as useful documentation when
looking at the file. You can't store a position in Z,Y,X order.
So basically, this just says:
1. where to start reading
2. how many positions to read
3. what is the stride between positions
4. positions are 3d
