On my Ubuntu 14.04, I have color depth of 24 as show by xwininfo -root | grep Depth
On windows I have color depth of 32bit. Why its less on Ubuntu ? Can I increase color depth to 32 ?
I have a scene I'm rendering using OpenGL ES in Android (using the Java libs). I want to apply some effects such as depth of field to the scene. I found a nice bokeh shader, and it needs a depth texture to do the job. What I need then, is to generate a depth texture to pass to the shader.
