Questioning Two Triangles that don't have Height Values

[JoshuaEir]

Hello. I am trying to understand if I am getting proper data for mesh of triangles related to the one height of my mapping array:

void addHillsManually()
{
	
	heightMapFromArray[20][20] = .5;
}

I am calling a for loop that gives me the data for all the triangles with any vertices having a value not equal to zero. I have attached an image of the hill in the mesh and also a diagram of the data I collected. The letter X on the two triangles are the triangles that had no data for any height value not equal to zero. The diagram is probably correct, but it is a different shape then what I expected and I am questioning if it is right, mainly the two triangles without any height. A1 through A3 are left triangles and B1 through B3 are right triangles. Across are the x values and upward are the Z (depth) coordinates.


Thank you, because this is mostly conceptual I did not feel the code is needed, yet.

- Oh, the dot in the middle of the diagram is the height value of .5 -
