I have half million km^2 triangles... still want to push out quads to triangles. Sigh.

Rows of quads to triangles...

These diamond quads...

Oops!

Quads in a Sinusoidal World Map

Oops!

Now that I can find the column and row, I can pick a point randomly or by clicking inside the sinusoid. I can walk to a random adjacent tile and make it land or sea, blue or green, or use position to generate a seed for a not so random number and average them with adjacent heights and subdivide quads into triangle fans with vertices above or below sea level.

Campaign?

I'm working on a solo game...

I should go back to the sinusoidal world map and then subdivide the quads and triangle pairs into adjacent parent triangle corner quads/triangle pairs.
