There isn't currently support in the PC version of Direct3D for re-starting/re-anchoring the current strip/fan primitive start point.

This is because up until recently, the majority of consumer PC graphics hardware (and their drivers) hasn't been able to do it natively (i.e. in hardware rather than faking it by converting to an indexed list inside the driver).


Degenerate "stitching" in your strips (most hardware handles indexed degenerates for free [or very close to]) and indexed triangle lists and are the best current alternative in D3D, and of course fans aren't of much use unless you're doing high poly cone and circle based things [wink]


Once re-starting/re-anchoring is widely supported in hardware, expect to see it in Direct3D (D3D10 will have a feature that allows this and much more...)
