[Qt5, Android] Setting up Qt 5.2 for Android

I guess I won't need much words as most things can be seen in the pictures.
I hope it works for you as simple as for me.
Have fun!

Linux Logitech Mouse Config

There is this nice config thing in KDE where you can tweak your mouse. You can find it in systemsettings or directly via "kcmshell4 mouse"

[How-To] Streaming audio and video on local network

I just wanted to stream some videos and music from one PC to another because that other has loudspeakers connected and a bigger screen. But how to do that?

The simplest thing: copy the files over.

[Ludum Dare] 27 Jam entry

This weekend was Ludum Dare 27. The theme was: 10 seconds
Here some stuff I posted here and there.

[C++11] Performance of casting and pointer

I played around with C++ trying to decrease build time by using pimpl and a base class.

Having some arbitrary base class in the pointer I need to cast it to the real data type when I wanna use it.
For the pointer I tried *, shared_ptr and unique_ptr and took times with and without casting.

Qt 5 on Android - getting started

For our master thesis we need a quite easy way to create applications for different platforms and systems. For now the main targets are Windows, Linux and Android. The simplest way would be HTML5. It should run here, there and probably everywhere. But the performance isn't that great for what we want to achieve. Java could be an option as long as we won't go in the direction of Apple. Another option is the use of something like Unity3D. But it is big, clunky and I won't be able to develop with it from my Linux machine.

Zusammenfassung meiner Arbeit mit und an der Blender Game Engine

Im Verlauf des letzten Semester durfte ich mit und an der Blender Game Engine austoben. Dies konnte man schon in meinen letzten Blogeinträgen lesen. Für das Fach Independent Coursework 2 habe ich nun mein Arbeit zusammengefasst.

Why I prefer "native" games

I like the movement of HTML5 and WebGL.
But I still prefer native gaming.
A simple argument: performance.
Just compare those two implementations.

[BGE, Qt5] Coding Blender Game Engine

The Blender Game Engine lacks features. But as it's Open Source you can improve it as you like.

I thought so myself and tried to do it. Here is a short log on what I did.

While working with BGE I found some points that could need improvement or would be nice to have implemented. Here is a little list I came up with:

[BGE + GLSL] GLSL Shader Repository Addon

The Blender Game Engine can make use of shader written in GLSL. In the standard version you can easily use vertex and fragment shader for your objects and fragment shader for post-processing (also known as 2D Filter).

Humble Bundle for Android 5 on Debian 64Bit

There is currently a new "Humble Bundle for Android 5" at https://www.humblebundle.com/

[SVN + Mercurial] Mirroring and using an SVN repository with Mercurial

For trying some code changes in the Blender Game Engine I needed its code. It is accessible via SVN from https://svn.blender.org/svnroot/bf-blender/trunk/
With Git and Mercurial around I'm used to do local changes, commit them locally and maybe undo them if I made mistakes. With SVN this is not possible.

[BGE + GLSL] Py GL Rant

Let's do this.

Blender Game Engine.
It is nice.

But it also has its problems. Just like everything else.
This time I had a hard time doing some GLSL shaders. Not the normal ones.

[BGE+GLSL] Finding interest points

Interest Points

I learned a bit in a class called "Computer Vision".

One thing was "finding interest points". 

Basically when you have a picture and give it to your computer it doesn't know anything what to do with it. It's just plain boring data. Every point is as interesting as every other. On some images you might have the same feeling. On others you recognize things which gives it more value then just color. 

But what makes the difference?

How do you see something?
