Fighting with DirectX 11 - part 2

I've just finish my first demo in Direct3D11. It is not any wonder, probably, but I am very proud of it. I've added image galery to my blog, so you can see how the application is. There doesn't see it in the picture, but the cube is rotating. In the future, I am going to add textures and maybe lighting.

As you saw, there is one important change. I've decided develop the blog in english, since now. If you know me a little, you would think probably, that I am crazy - I don't deny it, maybe it is true ;D. I've resolved also, that I won't try to write any tutorials, lessons there or to teach anything there. Since this time I will place stricte informative notes, like in a diary or some kind of a log (I think from log is name b-log...), as I've done that in first paragraph.

And one matter else. If you see a mistake somewhere (in english, of course - grammatical or lexical), tell me about it, in the comment - for example. I realise that there will be a lot of them, especially in the begin.

Fighting with Direct11 - part 1

I've recently got onto 3D graphics and I resolved to code something interesting. As you know, some time ago Microsoft gave us a new SDK for DirectX11. As I always prefer to use the most recent technology I decided to give it a try. And from there the steep steps stairs began. Microsoft didn't show off very well with its SDK. Firstly, a manual is very succinct and there is no good tutorials. Secondly a new Effects system API and DXUT sucks. For example you have to compile those two on your own. But that's not the end of the story...

D3D11 introduces a concept of Downlevel Hardware - generally this feature allows you write an application in D3D11 for the hardware compatible with at least D3D9. I decided on the start to implement available tutorials from D3D10. Everything was going smoothly to the time, when I tried to run application. I had spent two days to get known why ID3D11DeviceContext::Draw(...) reports access violation error. Fortunately, I found a note on this blog. As it turned out it is impossible to use the Effect Framework from D3D11 on Downlevel Hardware without any hacks. The only solution I could find was modification of few lines of code inside the Effect Framework.

Happily, at last everything ended well and I saw a beautiful red triangle on the blue background. No more such suprises in the future!
