I began to play around with implementing trees in Iktsua today. I started with the basic tree model from the talented JerIn3D. I created a couple of the trees randomly spaced in a forest biome.

TREE1The trees were a bit boring, so I varied the heights and rotations.

TREE2The trees looked really close together so  I tried to space them out.

TREE3Things started to look better (to my programmer’s eye), but I noticed something while walking through the trees, they were all sort of uniformly spaced and sized. The random was too random, you could tell what I was doing. You can see that the trees are all close in size and spaced evenly apart:

TREE5_badI tried to think about how trees actually worked, and I have no idea if I am right, but I thought maybe the larger trees could have some smaller trees clumped near their base. Perhaps the larger tree dropped some seeds and the saplings grew up near it? Anyway, I tried making the tallest trees have a couple of smaller trees clumped around their base, the result looks a lot more organic to me:

TREE4

 

And the final result in game:

TREE6

Let us know what you think about anything (the models, the colors, the programming, the biome logic)! I would be especially interested in your ideas about how to make the forests look realistic and interesting while still randomly generating them.

As always, any support you can offer (either monetary or by simply playing our game) is greatly appreciated!
