Shader Editor - example 005.

Today I posted on my instagram three shaders created to be used as phone wallpapers using the Shader Editor Android software option.
Somewhere in my posts I specified that this android application allows you to create shaders and then you can add them as dynamic wallpaper on phone.
The three source codes are open-source and you can test and use them with the android application and they will run very well as wallpapers:
This is a shader that I like as a design because it is relaxing and I put a more feminine color because spring is coming.
#ifdef GL_ES
precision highp float;
#endif

#extension GL_OES_standard_derivatives : enable

uniform float time;
uniform vec2 resolution;


void main( void ) {
vec2 uv = 0.5-(gl_FragCoord.xy - resolution * 0.15) / max(resolution.x, resolution.y) * 5.0;
uv *= 1.0;

float e = 0.0;
for (float i=3.0;i<=16.0;i+=1.0) {
e += 0.081/abs( (i/11.) +sin((time/1.20) + 0.18*i*(uv.y) *( cos(i/2.10 + (time / 11.0) - uv.y*.4) ) ) + 2.5*uv.x);
gl_FragColor = vec4( vec3(e/1.6, e/18.6, e/1.6), 1.0);

}

}
This is a dynamic sin cos combination
#ifdef GL_FRAGMENT_PRECISION_HIGH
precision highp float;
#else
precision mediump float;
#endif

uniform float time;
uniform vec2 mouse;
uniform vec2 resolution;

void main( void ) {

vec2 p = ( gl_FragCoord.xy / resolution.xy ) -0.5;//+ mouse / 4.0;
// float color = 0.0;

float sx =cos(0.123*time)*(p.x)*sin(7.6*p.x-0.5*time);
float dy =1.1/(1000.*abs(p.y-sx));

float dy2 =(50.*abs(p.y-dy));
float dy3 =(150.*abs(p.y-dy));

gl_FragColor = vec4( vec3( .01, dy*dy3 ,dy2*.1),4);

}
This shader has a darker style:
#ifdef GL_ES
precision mediump float;
#endif

uniform vec2 resolution;
uniform float time;

mat2 m(float a) {
    float c=cos(a), s=sin(a*1.0);
    return mat2(c,-s,s,c);
}

float map(vec3 p) {
    p.xz *= m(time * 0.1);p.xy*= m(time * 0.1);
    vec3 q = p * 4.0 + time;
    return length(p+vec3(sin(time * 0.17))) * log(length(p) + 0.10) + sin(q.x + sin(q.z + sin(q.y))) * 1.8;
}

void main() {
    vec2 a = gl_FragCoord.xy / resolution.y - vec2(0.5, 0.5);
    vec3 cl = vec3(0.0);
    float d =0.15;

    for (int i = 0; i <= 5; i++) {
        vec3 p = vec3(0, 0, 4.0) + normalize(vec3(a, -1.0)) * d;
        float rz = map(p);
        float f = clamp((rz - map(p + 0.1)) * 0.5, -0.1, 1.0);
        vec3 l = vec3(0.1, 0.3, 0.44) + vec3(1.5, 1.0, 1.0) * f;
        cl = cl * l + smoothstep(0.5,0.31, rz) * 0.16 * l;
        d += min(rz, 1.0);
    }

    gl_FragColor = vec4(cl*8.0, 1.0);
}

News : Promenade - Demo Launch Trailer ...

News : ... about new about Google Analytics 4.

I found at Google.com analytics academy this message that urges us to go through the courses from the skillshop.exceedlms.com website.
It seems to pass this is quite important if they offered free courses:
These courses are about Universal Analytics. Starting July 1, 2023, standard UA properties will stop processing data (July 1, 2024 for UA 360 properties). Learn about Google Analytics 4, our next-generation measurement solution, with these free courses on Skillshop.
