Rainbows

Ok, considering I have no idea what I'm doing, I think this is a pretty good step in the right direction... I mean, actually I was impressed that I even got anything to show up on the screen. :P
Here's my first try at a 2.0 shader for rendering a rainbow:

If you don't know what you're doing and you did that then it gives me hope that maybe I'll actually be able to get somethig working :)

Awesome! Do you plan to give this out for others to use? Pweez?

If you havnt already check out the 'Rainbow Fogbow' sample in the NVIDIA SDK 9.5, if your looking to be uber accurate, then the 'Refractive Dispersion' sample.Good luck!

NVidia has a converter that will convert shaders / fx into something that OpenGL can use, so eventually this will work on OpenGL as well.
Still working on this, though... I tried an approach that isn't going to work, so I'm taking a step back and re-designing a portion of it. I do plan on posting as a resource once it's finished. It will show how to make a fxRenderObject that uses custom FX / shaders. I may wind up changing fxRenderObject a bit so it can be used as a base class.
This isn't going to be done for a few days. I'm always all over the place so I don't get bored... kinda like an ADD programmer, but I'll get back to this soon.
Today I'm modeling. I'm using MakeHuman 2.0 (Winter alpha) to create a base mesh, then optimizing it, skinning, adding skeleton, etc. Blender rocks. I don't have the weights set correctly, so some of the animations don't look right, but I have a walk and run sequence for front, back, left, right, plus a look animation, and got it all in-game. It's about 8k polies, so I had to split it up into several meshes (Blender DTS exporter breaks with meshes larger than 3k-4k vertices) but the animation looks pretty good.

I'm actually using the Rainbow Fogbow from the NVIDIA SDK's fx... FX Composer is awesome. I'm not using any of NVIDIA's libraries, though. For now I'm cheating a little and not using the GFX libraries (making straight DirectX calls). I'm going to wait until the new SceneGraph and some other stuff in TSE is finished before submitting a resource that modifies those... I'd hate to break something.

I got rid of the nasty noise (one of my render to texture images wasn't being used yet and I forgot to initialize it. Now... if only I could get the transform right. It just overlays the screen right now, so the rainbow image stays the same. It's a little washed out because I'm looking right into the corona.
... and off I go again.
