I am sorry, Oculus. But I'm not going to use you SDK Rendering and will invest another 30-60 hrs trying to replicate the ovr distortion myself.

Oculus SDK OpenGL Rendering saves most states of gl twice every frame. I didn't count, but I'm guessing that is at least 25 glGet calls per eye per frame. That's 75 * 2 * 25 = 3750 glGet calls per second, if you want to think about it that way.

I guess doing the distortion rendering myself will take alot of effort, but once it's done, I hope it will be superior in performance.

Please don't get me wrong, though: I don't think it's bad, that Oculus saves and restores states before and after doing it's gl calls. I just don't want to accept the performance loss this brings for me, also, they did forget some flags, which I would have to manually save and restore to fix my rendering with Irrlicht. 

Today I was surprised to be reminded of my tumblr blog beeing three years old now. I guess this is a good excuse to write about what I have been doing and not blogging about the last year.

Obviously I have been studying, which may have helped the inactivity alot. But also, I gathered a small team of 15 people (including me), 2D/3D artists, coders, producers/sounddesigners, and even a story writer. I wrote more than 10k lines of code for an awesome gameengine, component based in an unconventional way, but a very neat structure indeed.

We call ourselfes "Vhite Rabbit", abbreviated VR, which already says what we do ;) We have the Oculus Rift DK1 and ordered DK2 already. The engine already supports the first and the latter will require not more than maybe 5-10 lines of code. 

Honestly, getting Oculus SDK 0.3.2 rendering to work with Irrlicht required some dirty hacks, but at least it works and it works great!

If you want to follow our progress, we are currently just starting up again (most of us study, so this turns out to be more of a vacation project), but here are some links:
