Strangely enough I have never done the following.  I need to convert a TriangleArray to a TriangleStripArray.  How does one do this type of thing???

You need to calculate the new vertices. Check how the real positions are, but let's assume, it is the following:

 1  2  3  4  5  6  7  8  9  10  11  12  13  14 `TiangleArray:          TiangleStripArray:3        4             4        3+--------+             +--------+|\       |             |\       || \      |             | \      ||  \     |             |  \     ||   \    |             |   \    ||    \   |             |    \   ||     \  |             |     \  ||      \ |             |      \ ||       \|             |       \|+--------+             +--------+1        2             1        2`

Just calculate the right vertices for the other format and it should be done.

Hmm Qudus you suggest a way to convert TriangleArrayStrip to TriangleArray, but hawkwind wants to do the other way round.
Have a look at nvidia stripifier. Don't know how it really works, but maybe *you*'re the one which makes it widely used, who know ?

Please keep us informed of magnificent performance boosts ! ^^

This can certainly be . I didn't really remember how these ones were built. But the priciple should be just the same.
