|Larger terrain! Now with multiple colours! Fog!|
This features a lot of major improvements over the previous version, most of which should be immediately obvious. I am now using fog to slowly blend the far away terrain into the background colour, which is useful for culling distant polygons discreetly.
The second major change is that the terrain is no longer a flat green colour due to the introduction of a sand / dirt colour. This colour value is based on the height of the terrain, when the terrain falls below a certain constant height it smoothly transitions into a yellow colour. I will most likely expand on this further in the future to include other terrain types, such as cliffs which would most likely be based on the gradient of a surface, rather than the height.
The final change is a much larger section of terrain is now being rendered. I have updated the terrain rendering so that it can now render arbitrary numbers of terrain sections. Splitting the terrain into discrete sections will be useful later on when I make the terrain be created dynamically as the user moves around the world. The aim is to be able to dynamically generate new terrain to the world as the user moves around, while also being able to remove terrain that is no longer in draw distance from memory.
