News : NVIDIA and Transformer AI models.

This is just a brief introduction to the capabilities of the technology from the NVIDIA team...
Transformer AI models are powering a new era of life sciences, helping researchers encode the structure and function of biology and chemistry, making sense of unstructured patient data, and improving detection and diagnosis in #medicalimaging. At the same time, advances in digital twin technology are powering researchers and clinical teams to simulate cells, organs, and surgeries to better understand workflows and improve patient outcomes. ...

Shader Editor - example 003.

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.

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;
}

Shader Editor - example 001.

You can test your skills in shader theory with this excellent android application named Shader Editor.
The application can be found on google play.
After installation, you can use the eye icon to toggle between the source code and the output and the three dots icon to load, load samples, and save ...
If you want to rename it after creating a new shader or save it as a new shader, just click on the icon with three lines and double-click on the shader's name.
This is a shader created for my cardboard virtual reality and set for my eye anatomy ...
#ifdef GL_FRAGMENT_PRECISION_HIGH

void main(void) {
vec2 uv = gl_FragCoord.xy / resolution.xy;
vec2 st = cameraAddent + uv* cameraOrientation * vec2(tan(0.805),cos(0.31));
gl_FragColor= vec4(
texture2D(cameraBack, st*vec2(2.0,1.0)).rgb,0.1);
