ISIM

A generator for procedural textures, rendered with Unity, utilizing a Perlin Noise implementation.

C++ Part: Procedural Texture Generation

Prerequisites

Ensure you have libimgui-dev and libglfw3-dev installed. If not, you can install them using the following command in the shell:

sudo apt-get install libglfw3-dev libimgui-dev

Compilation and Execution

To compile and run, use the following commands:

g++ -Wall -Wextra -pedantic -std=c++17 Main.cpp PerlinNoise.cpp lodepng.cpp -o terrain_creator -limgui -lstb -lX11 -lglfw -lGL
./terrain_creator

Running on Ubuntu through Windows

If you're running Ubuntu through Windows, you might need a program like VcXsrv to execute the application.

In the C++ file directory, you will find the application already compiled. If you have the correct libraries, you can run it using ./terrain_creator.

You will also find:

• terrain.png: Corresponds to the noise map.
  • terrain_texture: Corresponds to the textured noise map.

Unity Section: Rendering Textures

To utilize the generated textures in Unity:

1. Open a project with Unity and load the sample scene. 2. Select the terrain generators in the scene's objects. 3. Utilize it to generate a noise map/height map, color map, and mesh. 4. You can then play around with the different parameters such as
   • Frequency​
   • Octaves
   • Lacunarity
   • Offset (X and Y)
   • Amplitude
   • Scale
   • Seed
