/* coord transform functions
types of functions in glsl:
coordinate transforms receive coordinates (vec2) and output coordinates. i.e. rotate, repeat, scale, modulate? f(xy) => (xy)
color transforms receive a color (vec4) and output a color (vec4) i.e. saturate, invert, hue f(c) => (c)
composite transforms receive two colors and output a single color (vec4) f(c0, c1) => (c)
src transforms receive coordinates and output a color i.e. gradient, oscillator, tex2d f(xy) => (c)
example code: var rotate_osc = osc().rotate() var inverted_image = src(s2).invert() src(s1).mult(rotate_osc).add(gradient()).modulate(inverted_image).out(o1)
var addComp = function(f){ return function(g){ return function(h){ return function(x){ return h(f(x))(g(x)) } } } } // to do: // 1. how to validate inputs? and in certain cases apply more functions. i.e. needs color but passed in texture, automatically apply tex() command //2. how to specify functions that can receive different types //3. any parameter can accept a static variable or a function (! //4. evaluate block of code like in gibber, highlight when evaluating)
