Note to self - don't be stupid

If your Domain Shader expects a constant buffer and you don't give it one, you might - surprise frickin' surprise - not see anything rendered on screen.

So I was running around plugging in some SO logging and when it came to bind my SO output I scratched my head wondering why I had a //TODO: Set constant buffer here comment in my code.

Someone, please bang my head against the nearest brick wall.

For you, we will import only the finest bricks for your soon-to-be head-bashing.

At least you were smart enough to add a "TODO" ... sometimes, I forget to do even that.

your debug output makes me so hawt.

I agree with Dennis - any chance to get a quickie tutorial about your SO data logging system???

I'm honoured, thanks! Can I request highly tessellated brickwork?

Quote:any chance to get a quickie tutorial about your SO data logging system???

Yeah, I was amazed it worked so well - when it was mentioned at the summit it was almost revolutionary, I had simply never thought of using SO for debugging before!

I intend to tweak and enhance the output tonight or tomorrow evening, at which point I'll write it up in more detail. My provisional plan is to post fragments of tutorial/info about D3D11 tessellation here and then collect them together for a proper article when its more mature.

Watch this space [cool]
