Multiple declarations - One VB

I just realized that i would still need to call SetStreamSource to specify the offset and stride parameters.

I'm still curious though. Would it work?

I've not tried it, but I don't think you can... but if you used an "FVF-less" VB then I guess you might be able to hack around it.

For your situation, have you considered using multiple vertex streams? That way you could have a VB with the POSITION/COLOR components and a second VB with TEXCOORD data. Then use the declaration to pull data in accordingly...

Thanks

I figured it might be considered a hack (or at least undocumented). I'd like to keep this clean.

I'll probably go for multiple streams. The performance penalty is pretty small compared to interleaved arrays right?

I've not seen any performance comparisons between multi-streams and regular interleaved data. Unless someone else wishes to post their results in this thread, you'll probably just have to go ahead and try it [smile]

In theory, some situations will require less state-changing due to a multi-stream design, such that a performance gain would be expected.

IIRC, it will work.
