Pydroid 3 android application for python ...

The Pydroid3 android application is the best way to test and run python scripts.

I install python packages with the install option, the pip command on terminal comes with errors for same python package.

I used the free version but if you pay for monthly or lifetime then you can have more features.

Same team come with android applications to have add more features, see these IIEC team appplicatons.

News : Online tool for JavaScript and TypeScript

Using this online tool you can create a JavaScript/TypeScript project that runs natively on all your users' devices: web, android, iOS.

You can find more details and the documentation on the official page with the documentation.

An very old video example from 7 years ago, see the official youtube.

Here is a screenshot of this online tool I tested today:

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);
}

The Ren'Py visual novel engine .

Ren'Py is a visual novel engine – used by thousands of creators from around the world – that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.

Ren'Py is free to use with commercial and non-commercial games and you can find on the official website.

This run's on Android 5.0+,HTML5/Web Assembly (Beta),Linux x86_64/Arm,Windows 7+,Mac OS X 10.10+ and iOS 11+.

This is last video tutorial from RenPy start tutorials but you can find more on web.

News : Online tool for assembly with simulator and debugger ...

CPUlator is a full-system Nios II, ARMv7, and SPIM-compatible MIPS simulator that runs in a web browser. It is designed for education use to teach computer ...

This runs inside a web browser.

• Instruction sets: Nios II, ARMv7, and MIPS
• I/O devices:
• Nios II and ARMv7: Includes most devices found on a DE1-SoC (and other board models used by the Altera University Program), including interrupt support.
• MIPS: Includes SPIM-compatible terminal
• Nothing to install: Runs entirely inside a web browser
• Debugger: Single-step, breakpoints, watchpoints, trace, call stack, examine disassembly, memory and registers
• Debug assertions: Optional runtime assertions catch many potential errors
• Input: Accepts both assembly source code and ELF executables

I tested with the simple basic assemnbly source code and works well:

.global _start
_start:
	mov r0,#1
	mov r1,#3
	push {r0,r1}
	bl get_value
	pop {r0,r1}
	B end
get_value:
	mov r0,#5
	mov r1,#7
	add r2,r0,r1
	bx lr
end:

You can save, load and compile this sorce code like a simple file type : simple.s

This is the result:

Shader Editor - example 004.

Another example with the Shader Editor android application, this time simpler:

This shader displays some concentric circles that change their colors according to a sine and cosine formula.

This is the source code for the shader:

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

uniform vec2 resolution;
uniform float time;

void main(void) {
 float mx = max(resolution.x, resolution.y);
 vec2 uv = gl_FragCoord.xy / mx;
 vec2 center = resolution / mx * 0.5;
 float t = time * 10.0;

 gl_FragColor = vec4(cos(t+distance(uv, center) / 222.0)+1.0,
  vec2(sin(t - distance(uv, center) * 76.0)) * 10.5,
  1.0);
}

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

uniform vec2 resolution;
uniform vec2 cameraAddent;
uniform mat2 cameraOrientation;
uniform samplerExternalOES cameraBack;

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);
}
