Terrain Texturing Demo

[Luuk van Venrooij]

Hi All,

Currently I`m implementing terrain rendering at work. I have lots of experience with terrain texturing when it comes to shaders but none with old school stuff. Since our games need to run on hardware of +- 7 years old I can`t use shaders. So I did some research and wrote this proof of concept demo. It textures the terrain using multible passes with alpha blending. Basicly the same as quake 3 and unreal engine 2 do it. Lighting is vertex based and is done with an extra mult pass. You can have as many layers as desired. It could probebly be optimised with some multi-texture stuff.

Controls:
Mouse + WASD for movement
F1 for wireframe
See settings.ini to set the low detail terrain.

Source like always is GLPL.

Looks very nice and runs smooth on my computer I was always wondering how to do this without shaders... I'll definitely be poking around that source sometime

Thanx I presented my technique to the engine and art team and I got a greenlight. They also want a little tool to build and sculpt the heightmaps. I`m probebly going to create that in delphi

I'm very very curious how you do multiple passes without multitexturing? Mainly how do you keep depth test without flickering?

[Luuk van Venrooij]

By setting the depth function to GL_LEQUAL

Oh that was simple Thanks.

Alright who broke it?

Neat demo, I'll be sure to check it out once I get home.
