Shadertoy: Build a cross intersection - 001.

Based on this tutorial created by Inigo Quilez I created a new cross intersection shader:

The shader is very simple.
I created a black box and then colored all the areas in the corner of this box with black.
I left a white area to see the cross.
You can see better if you change this line of source code:

...into this:

p_m = 1.0-p_m/(p_m+0.1);

or this:

p_m = 1.0-p_m*10.0/(p_m*10.0+0.1);

The shader can be ru and testd here:

News: Cyberpunk 2077 coming to PC !

Shadertoy: Build a geometric pattern - 001.

In this tutorial I will show you a simple geometric pattern created with the dot, sin and values taken by the mouse.
This example was built using shader toy online editor.
The source basket contains four lines of code.
The last line of source code is the output with data to display.
The other lines of source code are very simple to understand.
The values of a and b are values created by dividing fragCoord to iResolution of window ...
The fragCoord contains the pixel coordinates of the pixel where the shader is being applied.
The sin_dot will compute the sin of dot from a , b and mouse position.

New Krita 4.4.1 released.

Today, 29.10.2020, version 4.4.1 of the Krita drawing and animation program was launched.
You can download it and read more on the official website.
The development team comes with this useful information: Despite an extra-long beta period during which we got awesome feedback from our community, 4.4.0 was released with several regressions, that is, bugs that weren’t present in 4.3.0. So today we’re releasing Krita 4.4.1 with the following fixes: ... NOTE for Windows Users: Microsoft has changed the way applications signed with certificates are handled. Only Digicert certificates are automatically trusted, other certificates will only be trusted if enough people bypass smartscreen to run the signed application. If you see the “Windows protected your PC” screen, press “More Info”, then select “Run anyway”. The more people do this, the earlier Microsofts machine learning algorithm will learn Krita is perfectly fine.

About Phaser Editor 2D game editor.

Today I install Phaser Editor 2D on Fedora 32, you can download it from the official website. Phaser Editor 2D is a commercial IDE to develop video-games.

Shadertoy: The sin math function - 002.

This is another shader example to draw a sine math function using a sine wave, see Wikipedia. I used shadertoy website and the mat sin function by time. The source code is commented for a better understanding of it.

// this size of line to paint each pixel from screen
const float size = 0.01;

void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    // Normalized pixel coordinates (from 0 to 1)
    vec2 uv = fragCoord/iResolution.xy;
    // resize uv 
    uv = uv  * 2.0;
    // translate normalized pixel coordinates uv from [0,1] to [-1, 1] with 
    uv = (uv - 1.0);

    // get uv.x aspect ratio
    uv.x *= iResolution.x / iResolution.y;
  
    // get simple sine 
    //float t = sin(uv.x);

    // get sine * 3 with same size uv will zoom the sine graphic
    // see also https://en.wikipedia.org/wiki/Sine_wave
    float t = sin(uv.x * 3.0);
    
 // select domain area of sine and drwa yellow color 
    // else put an blue color on rest
    if (uv.y >= t - size && uv.y <= t + size) {
        // draw sine
     fragColor = vec4(1.0,1.0,0.0,1.0);
    } else {
        // draw background
        fragColor = vec4(0.0,0.0,1.0,1.0);
    }
}

The result of this shader is this:
