Making music with maths Inigo Quilez 2011-07-12 | How to make some basic music with maths.Support this channel: patreon.com/inigoquilezThis videos shows some realtime capture of me typing some formulas to create sounds. As I type the formulas, the graph changes, and so do the sounds generated by them. Right next to the regular PC keyboard that I use to type the maths, I have a MIDI piano keyboard that sends some commands to trigger the formulas with different values for "w" (the "frequency", usually in most of the formulas). That way I can play small melodies as I tweak my mathematical sounds. Of course many varied types of sound can be created this way, although in this video I only show two.More info at http://www.iquilezles.org

real pixel coding Inigo Quilez 2011-04-11 | This is an example how little it takes to write a real-time animation effect (a textured tunnel in this case). 224 bytes are enough. Therefore, open photoshop, draw some pixels, save the image, rename it to as an executable, and let the x86 CPU execute it as native code. Et voila, an oldschool animation!More info here: iquilezles.org/blog/?p=1426If you want to support me, this is my Patreon: patreon.com/inigoquilez
