Cheesy tune for Raspberry Pi!

Music for nerds: https://soundcloud.com/rebb/this-is-berry-rasp
Highly repetitive, includes cheesy sounds and eurovision modulation. You have been warned.

Baby baby, come closer: this is berry!

Decided to do little tune for our beloved Raspberry Pi. Something different from the shader coding :)

Re: Really Fast Browser Inside! (mp4 video support)

Now works like a charm. New version and firmware update did the trick.
People with hdmi sound might want to edit /usr/bin/omxgtkplayer line
OMXPLAYER_BIN="/usr/bin/omxplayer.bin"
to
OMXPLAYER_BIN="/usr/bin/omxplayer.bin -ohdmi"

Re: Announcement: pishadertoy

It puzzled me why to use triangles instead of quad, but answer is obvious enough. There is no quad in Open GL ES 2.0 :)

Re: Announcement: GLSL live coder(yet another

So maybe you need to chang...

Re: Announcement: pishadertoy

http://www.youtube.com/watch?v=9N-2srAwLE8 Very nice. are these just for fullscreen visuals, or could you use them as textures on polygons? This is actually out of my knowledge, but my guess is that yes you can use them as textures. What puzzles me is in the pishadertoy code is int MyGLWindow::init...

Re: Announcement: pishadertoy

Got it posted, got it sorted myself :) triangle.v.glsl is the vertex shader pishadertoy is using. We need to pass an variable containing coordinates to fragment shader, so we declare new variable which type is varying, like this: varying vec2 texel2d; and in main we give texel2d same value than coor...

Re: Announcement: pishadertoy

Tool is working great, thank you!

I am little puzzled how to make shader that simply outputs texture.
Tried using gl_TexCoord but it does not seem to work at all.
Any opengl es specific shader tutorials to be found?
