Animate Noise Shader GLSL

2024-06-03 12:02 UTC gpt-4

I’ve got this setup in touch designer to produce a noise shader using a glsl top. This is the code. I now need to implement the animation properly so that the noise translates through the z axis to animate the noise pattern:

uniform int noiseType; uniform float frequency; uniform float scale; uniform float speed; uniform float lowClip; uniform float highClip; uniform float brightness; uniform float contrast; uniform vec2 iResolution; uniform float time; // For animation

// Output out vec4 fragColor;

// Simplex noise function vec3 mod289(vec3 x) { return x - floor(x * (1.0 / 289.0)) * 289.0; }

vec4 mod289(vec4 x) { return x - floor(x * (1.0 / 289.0)) * 289.0; }

vec4 permute(vec4 x) { return mod289(((x*34.0)+1.0)*x); }

vec4 taylorInvSqrt(vec4 r) { return 1.79284291400159 - 0.85373472095314 * r; }

float simplex(vec3 v) { const vec2 C = vec2(1.0/6.0, 1.0/3.0); const vec4 D = vec4(0.0, 0.5, 1.0, 2.0); vec3 i = floor(v + dot(v, C.yyy) ); vec3 x0 = v - i + dot(i, C.xxx) ; vec3 g = step(x0.yzx, x0.xyz); vec3 l = 1.0 - g; vec3 i1 = min(g.xyz, l.zxy); vec3 i2 = max(g.xyz, l.zxy); vec3 x1 = x0 - i1 + C.xxx; vec3 x2 = x0 - i2 + C.yyy; vec3 x3 = x0 - D.yyy; i = mod289(i); vec4 p = permute( permute( permute( i.z + vec4(0.0, i1.z, i2.z, 1.0 )) + i.y + vec4(0.0, i1.y, i2.y, 1.0 )) + i.x + vec4(0.0, i1.x, i2.x, 1.0 )); float n_ = 1.0/7.0; vec3 ns = n_ * D.wyz - D.xzx; vec4 j = p - 49.0 * floor(p * ns.z * ns.z); vec4 x_ = floor(j * ns.z); vec4 y_ = floor(j - 7.0 * x_); vec4 x = x_ * ns.x + ns.yyyy; vec4 y = y_ * ns.x + ns.yyyy; vec4 h = 1.0 - abs(x) - abs(y); vec4 b0 = vec4( x.xy, y.xy ); vec4 b1 = vec4( x.zw, y.zw ); vec4 s0 = floor(b0)2.0 + 1.0; vec4 s1 = floor(b1)2.0 + 1.0; vec4 sh = -step(h, vec4(0.0)); vec4 a0 = b0.xzyw + s0.xzywsh.xxyy ; vec4 a1 = b1.xzyw + s1.xzywsh.zzww ; vec3 p0 = vec3(a0.xy,h.x); vec3 p1 = vec3(a0.zw,h.y); vec3 p2 = vec3(a1.xy,h.z); vec3 p3 = vec3(a1.zw,h.w); vec4 norm = taylorInvSqrt(vec4(dot(p0,p0), dot(p1,p1), dot(p2,p2), dot(p3,p3))); p0 *= norm.x; p1 *= norm.y; p2 *= norm.z; p3 = norm.w; vec4 m = max(0.6 - vec4(dot(x0,x0), dot(x1,x1), dot(x2,x2), dot(x3,x3)), 0.0); m = m * m; return 42.0 * dot(mm, vec4(dot(p0,x0), dot(p1,x1), dot(p2,x2), dot(p3,x3))); }

float perlin(vec3 p) { // Implementing 3D Perlin noise here if needed return simplex(p); // For demonstration, using simplex as Perlin }

float box(vec3 p) { return step(0.5, fract(p.x) + fract(p.y) + fract(p.z)); }

float worley(vec3 p) { // Implementing 3D Worley noise here if needed return simplex(p); // For demonstration, using simplex as Worley }

float voronoi(vec3 p) { // Implementing 3D Voronoi noise here if needed return simplex(p); // For demonstration, using simplex as Voronoi }

// Utility functions float applyContrast(float color, float contrast) { return (color - 0.5) * max(contrast, 0.0) + 0.5; }

float applyBrightness(float color, float brightness) { return color + brightness; }

// Main function void main() { vec2 uv = gl_FragCoord.xy / iResolution.xy; vec3 p = vec3(uv * frequency * scale, time * speed); // Adding z-axis using time float n = 0.0; if (noiseType == 0) { n = simplex(p); } else if (noiseType == 1) { n = perlin(p); } else if (noiseType == 2) { n = box(p); } else if (noiseType == 3) { n = worley(p); } else if (noiseType == 4) { n = voronoi(p); } // Apply clipping n = clamp(n, lowClip, highClip); // Apply brightness and contrast n = applyContrast(n, contrast); n = applyBrightness(n, brightness); fragColor = vec4(vec3(n), 1.0); }

To animate the noise pattern by translating through the z-axis, you have correctly modified the main function to include time-based animation. However, let’s ensure everything is set up correctly for seamless animation. Here’s the updated GLSL code snippet, focusing on using the time variable to animate the noise:

uniform float frequency;
uniform float scale;
uniform float speed;
uniform float lowClip;
uniform float highClip;

// Output
out vec4 fragColor;

    if (noiseType == 0) {

}

Ensure the time uniform is dynamically updated in TouchDesigner, which it seems like it already is based on your setup.

This code includes the time-based z-axis translation to animate the noise. When you run this shader in TouchDesigner, the time variable will drive the animation, making the noise pattern appear to flow or move through the z-axis.

To debug and check if the time variable is updating properly, we can output the time value as a color in the fragment shader. This is a common technique to visualize numerical values in GLSL shaders. Let’s modify the shader to display the time value as a gradient color. You can use the fragColor to output the time value mapped to a visible color range.

Here is how you can modify the main function for debugging purposes:

// Main function
void main() {
    vec2 uv = gl_FragCoord.xy / iResolution.xy;
    vec3 p = vec3(uv * frequency * scale, time * speed); // Adding z-axis using time
    float n = 0.0;
    if (noiseType == 0) {
        n = simplex(p);
    } else if (noiseType == 1) {
        n = perlin(p);
    } else if (noiseType == 2) {
        n = box(p);
    } else if (noiseType == 3) {
        n = worley(p);
    } else if (noiseType == 4) {
        n = voronoi(p);
    }
    // Apply clipping
    n = clamp(n, lowClip, highClip);
    // Apply brightness and contrast
    n = applyContrast(n, contrast);
    n = applyBrightness(n, brightness);

    // Debug: Output the time value as a color
    float timeColor = mod(time * speed, 1.0); // Ensure the value is between 0 and 1
    fragColor = vec4(timeColor, 0.0, 1.0 - timeColor, 1.0); // Color gradient based on time value
}

This will output a gradient color that changes over time. The red channel will increase with the time value and wrap around, while the blue channel will decrease correspondingly.

After adding this debug code, run your shader in TouchDesigner and observe the output. You should see a gradient that changes over time, indicating that the time variable is being updated correctly. If the gradient changes, the time variable is functioning as expected. If not, there might be an issue with how time is being passed to the shader.

Please try this and let me know if you observe the gradient changing. If not, we can further investigate the issue.

Okay I’ve changed a few things and everything is working as intended. This is the current code:

// Output out vec4 fragColor;

// Simplex noise function vec3 mod289(vec3 x) { return x - floor(x * (1.0 / 289.0)) * 289.0; }

vec4 mod289(vec4 x) { return x - floor(x * (1.0 / 289.0)) * 289.0; }

vec4 permute(vec4 x) { return mod289(((x*34.0)+1.0)*x); }

vec4 taylorInvSqrt(vec4 r) { return 1.79284291400159 - 0.85373472095314 * r; }

float perlin(vec3 p) { // Implementing 3D Perlin noise here if needed return simplex(p); // For demonstration, using simplex as Perlin }

float box(vec3 p) { return step(0.5, fract(p.x) + fract(p.y) + fract(p.z)); }

float worley(vec3 p) { // Implementing 3D Worley noise here if needed return simplex(p); // For demonstration, using simplex as Worley }

float voronoi(vec3 p) { // Implementing 3D Voronoi noise here if needed return simplex(p); // For demonstration, using simplex as Voronoi }

// Utility functions float applyContrast(float color, float contrast) { return (color - 0.5) * max(contrast, 0.0) + 0.5; }

float applyBrightness(float color, float brightness) { return color + brightness; }

Can we please now add in a variety of different noise types, starting with this list from Cinema$D’s functionality:

Box Noise: Generates a noise pattern with a box-like structure. Blistered Turbulence: Produces a turbulence noise with a blistered appearance. Buya: A variant of Perlin noise, producing a smooth, organic texture. Cell Noise: Creates a pattern resembling cellular structures or Voronoi diagrams. Cranal: Generates a noise pattern that looks like crumpled paper or a wrinkled surface. Displaced Voronoi: A variation of the Voronoi pattern with displacement effects. FBM (Fractal Brownian Motion): Creates a fractal noise pattern, good for natural textures. Luka: A noise type with a mixture of smooth and rough areas. Naki: Generates a fine, grainy noise pattern. Noise: The basic noise type, similar to Perlin noise, used for general purposes. Nutous: Produces a noisy pattern with irregularities. Obscure: Creates a dark, cloud-like noise pattern. Poxo: Generates a noise pattern with a cellular, blocky structure. Random: Produces a completely random noise pattern. Stupl: Creates a stucco-like texture with rough, irregular patterns. Turbulence: Generates a turbulent noise pattern, good for natural effects like smoke or clouds. Voronoi 1, 2, 3: Different variations of Voronoi patterns with varying characteristics. Wavy Turbulence: Produces a turbulent pattern with wavy structures.

To add a variety of different noise types as requested, we’ll define the new noise functions and integrate them into the main function. Here’s an updated version of the GLSL shader code that includes the new noise types.

In this code:

I have added new noise functions to cover the different types you listed.
In the main function, I have included conditional checks to apply the correct noise function based on the noiseType uniform value.

You can select the desired noise type by setting the noiseType uniform to the corresponding value (e.g., 0 for simplex, 1 for perlin, 5 for blisteredTurbulence, etc.).

Please test this code in TouchDesigner and let me know if everything works as expected.

Sure, let’s implement the remaining noise types properly. For the noise types that were previously placeholders, I will provide the actual implementations. Here is the updated code with all the noise types implemented:

uniform int noiseType;
uniform float frequency;

uniform float lowClip;
uniform float highClip;

uniform float contrast;
uniform vec2 iResolution;
uniform float time; // For animation

// Output
out vec4 fragColor;

// Simplex noise function

In this code:

I have implemented proper functions for the noise types that were placeholders before.
The main function uses these noise functions based on the noiseType value.

You can select the desired noise type by setting the noiseType uniform to the corresponding value (e.g., 0 for simplex, 1 for perlin, 5 for blisteredTurbulence, etc.).

Please test this code in TouchDesigner and let me know if everything works as expected.

Sure! Here is a list of the noise types and their corresponding noiseType values:

Simplex - noiseType = 0
Perlin - noiseType = 1
Box Noise - noiseType = 2
Worley Noise - noiseType = 3
Voronoi Noise - noiseType = 4
Blistered Turbulence - noiseType = 5
Buya - noiseType = 6
Cell Noise - noiseType = 7
Cranal - noiseType = 8
Displaced Voronoi - noiseType = 9
FBM (Fractal Brownian Motion) - noiseType = 10
Luka - noiseType = 11
Naki - noiseType = 12
Nutous - noiseType = 13
Obscure - noiseType = 14
Poxo - noiseType = 15
Random Noise - noiseType = 16
Stupl - noiseType = 17
Turbulence - noiseType = 18
Wavy Turbulence - noiseType = 19

You can set the noiseType uniform in your shader to one of these values to select the corresponding noise type. For example, if you want to use FBM noise, you would set noiseType to 10.
