Offset Generator for GLSL Sandbox

gen_offsets.js

var size = 9;
var size_half = Math.floor(size / 2);

var offs = [];

for(var y = size; --y >= 0;){
    for(var x = size; --x >= 0;){
        var ox = x - size_half;
        var oy = y - size_half;
        var dist = Math.sqrt(ox * ox + oy * oy);
        if(!(ox === 0 && oy === 0) && dist < size_half){
            offs.push({ x: ox, y: oy, dist: dist });
        }
    }
}

offs.forEach(function(off){
    console.log("  vel += getSpring(prev, pos + pixel * vec2(" + off.x + ", " + off.y + "), " + ((1 - off.dist / size_half) / offs.length) + " * power);");
});

Forgive my naivete, what is process?

Oh. This is meant to run in Node / Plask. process.exit() quits the app ;)

Gotcha gotcha I ended up running your gist in in the console to generate the spring statements :)

Right on. I took out the process.exit() to make it agnostic. Node / Plask just happened to be the easier tool to reach for this time.

For sure, for sure. Thanks for sharing Ryan!
