ProceduralNoise

Noise generation and applications using various hashing techniques.

Pairing Function Implementations:

1. Linear Function
   • y * width + x
2. Cantor Pairing Function
   • ((x + y) * (x + y + 1)) / 2 + y
3. Szudzik Pairing Function
   • (x >= y) ? (x^2 + x + y) : (y^2 + x)
4. Rosenberg-Strong Pairing Function
   • (max(x, y))^2 + max(x, y) + x - y
5. Original Perlin Pairing Function
   • permTable[x + permTable[y]]

Noise Implementations:

1. Perlin Noise
2. Gabor Noise
   • Heavily based on the SIGGRAPH paper Procedural Noise using Sparse Gabor Convolution and related C++ implementation from Ares Lageo, Sylvain Lefebvre, George Drettakis, Philip Dutre, Katholieke Universiteit Leuven and REVES/INRIA Sophia-Antipolis.
3. Perlin Noise with Marble Perturbation
4. Worley Noise
5. Wavelet Noise
6. Perlin Noise with Splatter Perturbation
7. Perlin Noise with Wood Perturbation
8. Prime Gradient Noise
9. Phasor Noise
10. Better Gradient Noise

UI Implementation:

A user inferface, utilizing Dear, ImGui, has been implemented. This allows for an enhanced view and increased interaction with the application of which is rendered.

Building & Running:

1. CMake (Follow below or run within IDE - CLion or QTCreator)
   • Run cmake -H. Bbuild from inside main directory.
   • Run cmake --build build -- -j3 from inside main directory.
   • Executable located in /build/ folder and run with ./Perlin.

Other Considerations:

There are various modes that can be enabled/disabled in Driver.cpp.

1. Analysis Mode
   • Outputs <Type>Analysis_Pair<#>_Noise<#>_W<#>_H<#>.csv of which is used to analyze results of the various functions.
     • Type: Fournier or Amplitude
     • Pair: 0 - Linear, 1 - Cantor, 2 - Szudzik, 3 - Rosenberg Strong, 4 - Original Perlin
     • Noise: 0 - Perlin, 1 - Gabor, 2 - Marble, 3 - Worley, 4 - Experimental, 5 - Splatter, 6 - Wood, 7 - Primed Gradient
     • W: Width
     • H: Height
     • Ability to enable/disable amplitude and/or Fourier analysis.
       • Set ANALYSIS, ANALYSIS_AMPLITUDE and/or ANALYSIS_FOURIER accordingly.
2. Save Noise Image Mode
   • Saves an image as .bmp.
   • Set SAVE_NOISE_IMAGE accordingly.
3. Application type
   • Renders and saves generated noise in the following applications:
     • Texturing OBJ files
     • Procedural landscape
   • Set APPLICATION_TYPE accordingly.

Library Requirements:

1. Assimp
2. Eigen3
3. OpenGP
4. OpenGL
5. GLEW
6. GLFW3
7. OpenCV
8. OpenGL Mathematics
9. ImGui
10. Single-File Public Domain Libraries
