I have this WebGL fragment shader on my html file which is running fine, except when I call the first 5 vec2 functions. vec2 subCalc (vec2 z1, vec2 z2) { return vec2 ( (z1.x - z2.x), (z1.y - z2.x)); } It's weird because I use the vec4's, for example 'HSVtoRGB', the code runs fine. WebSign. float sign (float x) vec2 sign (vec2 x) vec3 sign (vec3 x) vec4 sign (vec4 x) The sign function returns 1.0 when x is positive, 0.0 when x is zero and -1.0 when x is negative. The input parameter can be a floating scalar or a float vector. In case of a float vector the operation is done component-wise.
