Shader Editor - example 002.

This post is just one simple example, you can find many tutorials if you search on web for my work ...

If you don't have enough time to test my last shader source code then you can test now with another source code to have a beautiful blue effect.

Let's see the source code for this shader:

#ifdef GL_FRAGMENT_PRECISION_HIGH
precision highp float;
#else
precision mediump float;
#endif

uniform vec2 resolution;
uniform float time;
uniform vec4 mouse;
uniform vec4 date;

//#define time  iTime
#define R resolution.xy
void mainImage( out vec4 fragC, in vec2 fC)
{

//   vec2 pos = (fragCoord.xy/R.xy) * 8. - 4.;
   vec2 pos = (fC.xy/R.xy) * 8. - 4.;
    pos.x *= R.x / R.y;
    float s = .25, f = .0, k = f;
    vec3 p = vec3(pos, sin(time * .4) * .5 - .5)* s;

    for( int i=0; i< 9; i++ )
    {
           p = abs(p)/dot(p,p)- 1.5;
           k = length(p) ;
           p = p*k+k;
   }

   f = dot(p,p)* s;
   fragC= vec4(f*.5, f *1.2, f * 5., 0.111);;
}

void main() {
vec4 fragment_color;
mainImage(fragment_color, gl_FragCoord.xy);
gl_FragColor = fragment_color;
}
