Demo Code: Sample RenderMonkey Code

After playing around with the code, here's what I got so far. Not pretty at the moment, tho.

Parallax Occlusion Shader Demo. First run.

Looks like the pixel is being pushed at a different axis.

Anyway...

Just curious...you know that shader requires a DX10 card or greater that supports GL_EXT_gpu_shader4, right?

So you could still work on implementing your own. I wouldn't say, in this day, that using the geometry shader is the best choice. So you could still give it a go, if you wanted.

I'm testing on an XP SP3 with a Geforce 8500 at the moment. Looks OK so far.

Hmm, maybe not...

Here's another one...

It's written in HLSL, which--oh my--not my forte.

Anyway...

Here's another test...using GLSL code.

Here's another try...parallax occlusion mapping glsl.

Hmmm, this one reminds me of Omaremad's bump-n-heightmap tool. Looks like I need to send him a PM.
