Surface-generation-and-texturing-with-compute-shader

Unity mesh generation script also adds custom texture generation with compute shader

Example usage

SimpleExample.cs

  public class SimpleExample : MonoBehaviour
  {
      public ComputeShader computeShader;
  	public Material material;

      public int width = 10; 
      public int height = 10;
      public Vector2 scale = new Vector2(1, 1);
  	
      GameObject surface;

      void Awake()
      {
          // (width * scale.x) x (height * scale.y) surface
          // verticies count = width * height
          surface = SurfaceGenerator.generate(computeShader, material, width, height, scale);
     }

  }

TexturedExample.cs

  public class TexturedExample : MonoBehaviour
  {
      public ComputeShader computeShader;
      public Texture2D texture;
  	public Material material;

      public int width;
      public int height;
  	
      GameObject surface;

      void Awake()
      {
          // Color per tile (if there is no texture it works for per pixel)
          Color[] colors = new Color[SurfaceGenerator.calculateColorsLength(width, height, Vector2.one)];

          // Setting random colors for visualisation
          for(int i = 0; i < colors.Length; i++){
              colors[i] = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f)); 
          }

          // (width) x (height) textured surface
          // verticies count = width * height
          surface = SurfaceGenerator.generate(computeShader, material, width, height, texture, colors);
     }

  }

YExample.cs

  public class YExample : MonoBehaviour
  {
      public ComputeShader computeShader;
  	public Material material;

      public int width;
      public int height;


      GameObject surface;

      void Awake()
      {
        // Color per tile (if there is no texture it works for per pixel)
        Color[] colors = new Color[SurfaceGenerator.calculateColorsLength(width, height)];

        // Setting random colors for visualisation
        for(int i = 0; i < colors.Length; i++){
            colors[i] = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f));
        }

        // has to be width + 1 and height + 1 
        float[,] y = new float[width + 1, height + 1];

        // Setting random length between 0 and 1 for visualisation
        // You can use noise function there
        for(int x = 0; x < width + 1; x++){
            for(int z = 0; z < height + 1; z++){
                y[x, z] = Random.Range(0f, 1f);
            }
        }

        // (width) x (height) colored surface 
        // verticies count = width * height
        surface = SurfaceGenerator.generate(computeShader, material, width, height, y, colors);
     }
