News : New videos from Cascadeur

... two months of news for the Cascadeur - the official youtube channel ... :

News : ... the fast version 5.0 of Blender 3D.

I have already seen that version 5.0 Alpha of the Blender 3D software is on YouTube channels. I assume the community is eager to test it. I have followed it and they have stagnated in development. You can see the way the development team works with a repository tool. It is not the only software that has fluctuations in development - Godot had the same progression.

I saw this video today named "Why Blender 5.0 is already getting crazy" from the 3Dan - the official youtube channel.

... and is not only one, most users not use the apha version of software :

The alpha phase of the release life cycle is the first phase of software testing (alpha is the first letter of the Greek alphabet, used as the number 1). In this phase, developers generally test the software using white-box techniques. Additional validation is then performed using black-box or gray-box techniques, by another testing team. Moving to black-box testing inside the organization is known as alpha release.[1][2]

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);
}

Blender 3D : Hidden Rigging Feature Makes Buildings Rigs EASIER! in Blender

Blender 3D : Glass material with Open Shading Language.

Open Shading Language (OSL) is a small but rich language for programmable shading in advanced renderers and other applications, ideal for describing materials, lights, displacement, and pattern generation.

OSL was originally developed by Sony Pictures Imageworks for use in its in- house renderer used for feature film animation and visual effects, released as open source so it could be used by other visual effects and animation studios and rendering software vendors. Now it's the de facto standard shading language for VFX and animated features, used across the industry in many commercial and studio- proprietary renderers. Because of this, the work on OSL received an Academy Award for Technical Achievement in 2017 ..., see the GitHub project.

Today I'll show you how to use this option with Blender 3D to create a glass-like material for an object and render it with Blender 3D.

Open the Blender 3D application and set the render to Cycles, CPU and check Open Shading Language, see the next image:

Add an object, add a new material remove the Principled BSDF node

Create a file named Glass_001.osl select this file in the material area for the object.

You can see in the image above how I set the material with a Script node.

Add this source code in the file and render the scene:

#include "stdosl.h"

#define IOR_THRESHOLD 1.000001

float FresnelDielectric(vector i, normal n, float eta)
{
    float c = fabs(dot(i, n));
    float g = eta * eta - 1 + c * c;
    float result = 1.0;
    
    if (g > 0) {
        g = sqrt(g);
        float a = (g - c) / (g + c);
        float b = (c * (g + c) - 1) / (c * (g + c) + 1);
        result = 0.5 * a * a * (1 + b * b);
    }
    
    return result;
}


surface Glass(
    color diffuse_col = 0.8, 
    float ior = 1.45, 
    output closure color bsdf = 0)
{
    float real_ior = max(ior, IOR_THRESHOLD);
    float eta = backfacing()? 1.0 / real_ior : real_ior;
    float fr = FresnelDielectric(I, N, eta);
    
    bsdf = diffuse_col * (fr * reflection(N) + (1.0 - fr) * refraction(N, eta));
}

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 ...

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);
}
