perlin noise experimentations

This is a simple project to experiment with perlin noise. The project is written in c++ using X11 for the windowing system. There are 5 different way to generate iamges using perlin noise built-in the project:

cloud effects using 2 superposed perlin noise
graph representation of perlin noise in 2D
marble effect
wood effect
one effect that I don't know how to describe

usage:

# clone:
git clone https://github.com/lohhiiccc/Noise-generator
# compile:
make
# run:
./perlin

how to use it:

press space bar to change the effect
press escape to quit the program

dependencies:

X11
g++
make

how it works:

The project is divided in 3 main parts:

the noise generation
- cache pseudo-random gradient vectors based on seed
- cut the image in a grid of cells
- for each cell, generate a pseudo-random gradient vector
- for each pixel in the cell, calculate the distance to the 4 corners of the cell and interpolate the gradient vectors
the image generation
- image are basically 2D array of uint32_t
the x11 windowing system
- open a connection to the X server
- get a default root window
- define window properties
- create the main window
- event handling
  - key press event
    - quit the program with escape key
    - change the effect with space bar
  - close window event

How to add effects:

create effect function in effects folder
follow the same pointer function signature as the other effects int (*name)(uint32_t *image, bool &needUpdate)
add the effect in the main.cpp file by adding the function pointer in the vector of function pointers window.load_render(<new_effect_name>);
make again the project !
