Post processing aa (fxaa)
Why post processing antialiasing ? Because of two reasons. A good and fast post processing filter like fxaa or cmaa can achieve almost the same visual output like the usual multisampling counter part (msaa) and costs way less on the GPU because you dont need multiple samples per fragment/pixel! Another restriction is the rendering pipeline you might choose. A deferred renderer uses multiple framebuffers to achieve multiple different effects and using multiple samples on each of those framebuffers might have a really big impact on performance. Additionally it is practically impossible to use mxaa in a deferred renderer, because multisampling the position framebuffer results in wrong values around objects! Let's have a look on the code: (more…)

Gamma correction
Gamma correction in openGL is very easily to achieve, but why do you need gamma correction? Let's keep it simple... First of all your textures you use as input for your openGL renderer are most likely in non linear color space. Your renderer on the other hand is probably calculating light under the assumption of linear color spaced color values in your loaded textures. So you might be working in two different color spaces. After your renderer is done it writes the colors to the screen, which uses non linear color space like your textures do! So what happens is, that your calculation might be visually wrong... So how can you solve this? The answer is very easy: (more…)
3D QT Engine
Skyboxes !!!
Not much to say, skyboxes add a lot to a 3D scene! Here are two early screens. Not everything works like it should atm, but it’s close!

Swapped my primitive OBJ loader for Assimp lib
Was easier than expected. I already had most of the classes prepaired for multiple formats so it was super easy to swap one format against a complete library that can load a bunch of different formats.
Here's a screen of assimp loading the OBJs...

Hwinfo android app almost done!
My new android app is almost finished. It uses a little server for windows to get sensor information from your desktop computer to send it to a client android device. It’s still a bit rough at some edges, but it should be done soon! Here is how it looks like:
