Here's a short TeamSpeak3 server update script that I am using from now on. It just needs the url for the archive as a parameter. One has to stop the service first and start it after the script completed. The copy command copies the downloaded files to ts3/ which is the directory where the actual ts3 server is located. Obviously this has to be adjusted.

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 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…)
