Well, saying "voxel landscapes can only be rotated around the y-axis" doesn't mean that...but then again, I can't take every article for the Gospel truth, now can I? Of course you're right (Delta Force), but I'm just wondering how it's done....
Ok. I just scanned through the flipcode tutorial and you may be right. I assumed that rotating about the X axis would be ok for that algorithm but maybe not. I'm not really bothered to work out why not.
Outcast and delta force may not use the raycasting technique though. The constraint to 4 degrees of freedom is only a side-effect of the raycasting technique.
If you want to make an engine just pick a technique an go for it. Raycasting is nice for people who prefer simple co-ordinate geometry to matrix math (Like me). I think you've got alot to go on with just that flipcode article.
Otherwise just try your nearest search engine for other techniques.
