Terrain Texturing

After I put in the camera rotation code from my last post, the teeth-like artifacts disappeared. I find graphical programs a real bitch to debug so I'm pretty happy to totally block from memory that they ever existed... what was I talking about? Oh yeah, texturing the terrain.

Instead of colouring the vertex based on how high it is, we'll texture it. With height-colouring it was simple to go from black to white, it's just as easy going from one texture to another - the technique is pretty much the same but the start and end colours are retrieved from a specific point on each texture. Blending is done as before, if the point is nearer the higher texture, the point will be closer in colour to the pixel from the higher texture and vice versa for the lower texture. Here's the result of applying 4 textures (earth, grass, rock and snow) to my terrain:

It looks more realistic, but a little bit blurry. The pit on the right looks black instead of earthy because I started blending off with a black colour as a base, I think it looks ok.

First post!!!!!

Hello! I'm writing this blog for purely selfish reasons - I've wanted to program games since I was a kid but have only once finished a project: a Nibbles clone with death sequences in DOS (I'll put up the exe if anyone's interested). A friend suggested that a blog can help so hopefully some sort of guilt for updating this blog will override my incredible laziness. He's got a game engine in development too and has made a lot of progress, it looks fantastic and you can see it on his blog - feel free to make me feel better and undermine him and his engine :)

So what'll my game be then? I don't know yet, but my ambitions are high - basically I'd like a procedurally created universe with super-intelligent AI with a combined RPG/FPS/Flight/Driving/Adventure gameplay that's fecking awesome. People will become addicted to my game and it will create world peace. Oh and I'll get the ride off of some hot groupies. But I've got to start somewhere, so here we go - a terrain (bit of land) generated with fault formation (raise sections of the land randomly) and lit with height lighting (the higher the whiter). These are real terrain basics so I won't go into detail (unless someone needs it).


Looks ok for a first go, but there are these weird artefacts, kinda like teeth, no idea what they are...
Until next time!
