D3D10 Not drawing primitives

05 July 2011 - 04:04 AM

In an attempt to learn Dx10 after becoming competent with XNA i have followed this tutorial: Here. I have completed the coding aspect of the tutorial as far as I am aware however, when executed, no colored triangle is visible. Short of dumping a large section of code here, I can say with some fair confidence that the problem lies in either my effect initialization, or buffer creation because I can still change the background color of the window in real time.

I will post any snippets you ask for but otherwise, any thoughts?

Tangent Space Transform Matrix

27 November 2010 - 07:50 PM

I have a current pixel shader that performs parallax mapping on a texture but only when the texture is facing straight up and is mapped on some polygons of a specific size.

I need to know how to calculate the tangent vector for that polygon. I have searched all over Google and GameDev and have yet to find a solution to my problem that either works or i fully understand.

Can anyone please explain in simple terms what i need and what i need to do and why, most importantly why.
