Topics I've Started

RFC: Modern Graphics Tutorials

14 November 2011 - 09:47 PM

Hello. While NeHe has in the past been an excellent resource for getting started with OpenGL, this has not been the case in the current shader-based era. Programmers weaned on fixed-function often have very difficult times coming to understand how things work with shaders. And with OpenGL 3.1 removing much of the functionality that the NeHe tutorials depend on, I felt that a void needed to be filled.

My attempt to fill this void are available on my website, and the source code download is also available. It's fairly lengthy, though unfinished.

I'm interested in commentary and criticism of my tutorials. The content, the source code, whatever. I get a lot of "Oh that's great" or the occasional bug report correcting a typo or some such. But I don't get any real, in-depth criticism from someone who actually knows this stuff, or to have a dialog with someone who's knew that doesn't really know what's going on. I'm mostly interested in whether I've explained concepts properly so that new users will understand them effectively. I also want to know whether I have missed some valuable concept in a tutorial. Or even just a debate about whether you think it was appropriate to wait until Tutorial 14 to start on textures (the reasoning is actually explained).

Before you start however, know this: my tutorial series is not complete. I know that I've barely scratched the surface of texturing; I've still got two more texture-focused tutorials planned (one that covers projective texturing, textures as lightsources, and cubemaps. And one that covers bumpmapping in various forms). I'm also well aware that blending and render-targets have not been touched yet. Again, those are planned for the future. So this isn't necessarily about what large features are missing, so much as how I can improve upon the structure I have designed. Or even commentary on whether you think that the structure is effective for teaching new programmers.
