Today I will show you how to change a shader from shadertoy website to a shader for Shader Editor android aplication.
Open my shader example from shader toy website.
#define f length(fract(q*=m*=.6+.1*d++)-.5)
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
float d = 0.;
//vec3 uv = vec3(fragCoord.xy / iResolution.xy,iTime*.2);
vec3 q = vec3(fragCoord.xy/iResolution.yy-13., iTime*.2);
mat3 m = mat3(-2,-1,2, 3,-2,1, -1,1,3);
vec3 col = vec3(pow(min(min(f,f),f), 7.)*40.);
fragColor = vec4(clamp(col + vec3(0., 0.35, 0.5), 0.0, 1.0), 1.0);
}In order to use it in the Shader Editor android application you need to make these changes:
#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 f length(fract(q*=m*=.6+.01*d++)-.5)
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
float d = 0.91;
vec3 q = vec3(fragCoord.xy/resolution.yy-13., time*.2);
mat3 m = mat3(-2,-3,6, 3,-1,1, 0,3,1);
vec3 col = vec3(pow(min(min(f,f),f), 7.)*40.);
fragColor = vec4(clamp(col + vec3(0., 0.35, 0.5), 0.0, 1.0), 1.0);
}
void main() {
vec4 fragment_color;
mainImage(fragment_color, gl_FragCoord.xy);
gl_FragColor = fragment_color;
}You can see these changes are n the first part of the source code and just one on time.
You can play with this source code then use the option Set as wallpaper to have it on your phone.
