Shadertoy: A simple round square.

This is a simple tutorial about how you can create a simple round square build using the math function sqrt and the shadertoy web tool.

The source code is very simple and all the lines of source code come with explained comments

Let's see the source code:

// create a function for round square 
vec3 round_square( vec2 uv )
{
 // Set the size of the square, can be changed .01 6.
 float square_dimension = 6.;
 
 // Create math function for round sqare shape 
 float my_square = sqrt(length(pow(uv-vec2(.0,.0),vec2(square_dimension))))-.1;
 
 //Set default poz 
 vec3 poz = vec3(1.,1.,1.);
 
 // Return the result 
 return mix(vec3(0.1),poz*poz, smoothstep(0.,.001,my_square));
}

// Set color for the round square
vec3 color = vec3(.1, 76., 76.);

void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
 // Normalized pixel coordinates (from 0 to 1)
 vec2 uv = (fragCoord-.5*iResolution.xy)/iResolution.y;
 // Set color 0,0,0,0
 fragColor = vec4(0);
 // u=Use for to build with round_square
 for (int i = 0; i < 10+int(min(0,iFrame)); i++) {
 // Set UV2 from basic UV
 vec2 uv2 = uv + 1. / iResolution.y * 1.25;
 // Create the round square
 fragColor += vec4(round_square(uv2) + color.xyz , 1.);
 }
 // show the square
 fragColor.xyz = (fragColor.xyz/fragColor.w);
}

This is the result:

Blender 3D : The new long-term support release version 2.83 LTS.

Aladin lite version of Aladin Sky Atlas.

Aladin lite is a lightweight version of the Aladin tool.

Aladin lite is powered by the HTML5 canvas technology, currently supported by any modern browser.

Aladin lite is easily embeddable on any web page and can also be controlled through a Javacript API.

This running in the browser and geared towards simple visualization of a sky region.
