Implemented Diamond-Square algorithm, want to visualize it

Thanks in advance for the help.

So, my Diamond-square algorithm generates a 2D array of floats,

Code (CSharp):

1. float[arrSize, arrSize] ds;

Basically, what I want to do is somehow visualize these values similar to this:


The first thing I tried was something like this:

Code (CSharp):

1. Texture2D texture = new Texture2D(mapSize, mapSize, TextureFormat.ARGB32, false);
2. cols = new Color32 [mapSize * mapSize];
3. Color32[] cols = new Color32(arrSize, arrSize);
4. int index = 0;
5.  
6. for (int y = 0; y <arrSize; ++y)
7. {
8.      for (int x = 0; x <arrSize; ++x) {
9.           cols[index] = computeColor(map[x,y]);
10.          ++index;
11.      }
12. }
13. texture.SetPixels32(cols);
14. texture.Apply();
15. renderer.material.mainTexture = texture;
16.  

and computeColor just returns a Color that depends on the range in which the float resides.

The problem is when I go to run this script all I get is one single color when I double click the texture. So I don't think I'm doing it right.

Anybody have any better suggestions?

 

Nevermind, I fixed it. Thanks a lot!
