Yes, Infinity is indeed one of my main sources of inspiration. Most of what I've done so far, I've picked up from his dev blog.
Also, I had a look at one of the ROAM terrain videos, and it seems that they are actually using high-resolution textures. However, when you view a high-resolution texture (say 1024) from a distance where the texture only spans a few pixels across, you will either get a lot of flickering (if you don't use any filtering), or the texture will look very low-res (if you use filtering) since you are actually seeing a mip-mapped version of the texture... My program is no different, I just chose to show you some screen shots that looked good.
If you read the Infinity dev blog, you will see InfinityAdmin say the same thing. The Infinity screenshots and videos look amazing, but that's just because he is hiding the ugly parts (like disabling the clouds in the 2010 tech video).

The alien sunset looks great! I definitely feel like I'm peering into a hazy sunset horizon.
About infinity - an amazing project, with very impressive graphics. But I wouldn't hold my breath for it to be finished anytime soon. The graphics tech started around 2004, so they're not in a hurry. And then there's those dreaded 3 letters of so many doomed projects - "MMO"
Still, I wish nothing for the best for the infinity devs and if it ever does reach completion it's certainly going to look good.

After living without a decent computer for over a month while waiting for my RMA'd graphics card to get returned to me, and then moving to a new city, I am now back to coding. Here's a small video for you.

Frame rates are around twice of that shown when not recording. Will try to get started with batching terrain patches now, some experimenting shows that will also help quite a bit with the frame rates.

You didn't actually commit anything, am I right?
But great to see that you're back to working on it.
The vista in that video looks natural.

I did, but I removed it again due to a licensing issue. Basically, I want to release source under MIT license but there's some GPL code in there. The GPL code isn't strictly needed, but it's the part that generates the terrain... I haven't really gotten around to write my own complex terrain generation code, so the terrain would look much less interesting without it.
I'm thinking about doing a dual release - one release with this terrain under GPL, and one release without it under MIT, but I don't know if that would be a good idea.

Let me guess, it's Mercator?

You can always release under MIT later when the dependancy is gone. I am sure people want to play with it regradless

Mercator is Worldforge's terrain generator library:
http://worldforge.org/dev/eng/libraries/mercator
I truly hate that it's GPL.
But I was merely trying to trick you into revealing what library you're using now. And I failed.

Aha. You could have just asked, it's no secret.
I've adapted the planetary terrain example from libnoise, although I'm using noise++ for the actual noise generation.

In that case it shouldn't take you too long before you've made that code your own.
It's an example, and you are meant to learn from it - not copy it, of course.
Libnoise is truly amazing.

G'day lingfos,
I like Noise++ myself, well, that is what I've loosely based my fractals off of, Eats LibNoise alive for performance, and produces a similar result.
The first incarnations of my Planet engine used a custom FBM fractal mixed in with a RidgedMultiFractal hanging off of a Perlin Noise function
I soon changed to LibNoise, and I got nice results, then I switched to Noise++ and got the same results, with better performance.
I now use a noise++ permutation, I use the noise++ routines, plus a couple of my own intermediary functions and a couple of my own base fractal algorithms,
I'm still proofing them at the moment, but when I'm done, I will have fully predictive erosion and stuff like that. Yes I will give this stuff away with my system when I release it. SHIT!!! I'm ranting again.
Stick with noise++ for now lingfos, it's a great base system to work from.
Alex

video looks great. i take its all generated randomly?

Source code now available at bitbucket again.
Terrain textures are missing though, because I can't remember where I found them, and thus can't check the licenses.
