Right, I spent most of yesterday and today putting together the rendering process described in my previous entry.

Its mostly the framework rather than the "meat" - all it currently does is allocate/deallocate resources and then do the buffer swapping/clearing parts.

Problem is, that it's a tiny bit slow. Already.

I'm getting 20-24 frames per second, and all it's doing is clearing a few buffers and performing the additive blend on 9 imaginary lights.

If I reduce the number of passes/lights down to 2 then the performance takes a jump up to around 80hz.

That and I think I might have found a bug with PIX [rolleyes]

Oh, and because all good journals include pictures:

The Vista December CTP is out? Nice!

Btw, what other D3D10 articles have you made/are planning to make? If you want any assistance or anything, I'd be glad to help out :)

Well it's out for the beta testers - might be a few days for the main MSDN subscribers...

I've been waiting to get the December CTP of D3D10 running before I write anymore code/articles - best to be using the latest version and all that [smile]

Could be interesting to collaborate on something though. Got any ideas?

Well, here's one idea: I had a significant difficulty understanding how buffers, textures, and shader resource views all worked together, what the multiple bind flags being used in conjunction results in (I'm _still_ not entirely sure how to get something like a RT/VB setup would work properly, that's something I may want to experiment with later) and how to use them properly. I know you touched on them in your VB article, but that was more one application out of a possible many.

Interesting... given that D3D10 seems to have undergone some of the biggest changes to resources for at least a few major API revisions it could be a good topic to cover [smile]

Admittedly, that is by far the fastest download I've achieved on this connection. Everyone else has gone home for the christmas break - so I probably have most of the university network to myself...

Read: I am the only NERD who has not gone HOME, but opted to stay and work with Direct3D 10 instead...
