Each group is an object of the form:
<code>
{ start: Integer, count: Integer, materialIndex: Integer }
</code>
where start specifies the index of the first vertex in this draw call, count specifies
how many vertices are included, and materialIndex specifies the material array index to use.
<br
/><br
/>
where start specifies the first element in this draw call – the first vertex for non-indexed geometry,
otherwise the first triangle index. Count specifies how many vertices (or indices) are included, and
materialIndex specifies the material array index to use.
<br
/><br
/>
Use [page:.addGroup] to add groups, rather than modifying this array directly.
