Terrain - Multi-texturing

Alright, what we have now is directional light lit terrain with sharp textures and no distortion. Although green is my favorite color it is obvious that real terrain is not consistent regarding its surface, its texture. We can enhance the visual appearance of our terrain by using multiple textures.

We will cover different parts of our terrain with different textures and we will have intermediate parts where two textures should blend to each other, that is more than one texture will be applied to the same fragment which is called multi-texturing.

Terrain - Triplanar UV mapping

The visual appearance of our terrain got better with anisotropic filtering but there is still one major visual artifact that bothers me: texture distortion on steep slopes.

To fix it we should use a more advanced texture mapping technique. Let's try triplanar mapping.

Terrain - Anisotropy

First thing I noticed regarding the visual appearance of my terrain is that parts of it are to blurry. And this makes my terrain look less realistic.

To solve it let's use anisotropic texture filtering.

Terrain - Getting started

It's time to start some real work now. :)

This time a big part of my game design gets revealed because as the title indicated the game will be played outdoors and I'll need a terrain for that.
