Terrain LOD

By David on September 23rd, 2006

Dynamic terrain level of detail is working now using a form of patch-based geomipmapping; this means that we can seamlessly render distant terrain at lower level of detail, so polygon count does not increase exponentially as view distance increases. This means that we can make the far clip plane much farther away while maintaining high framerate, so you will be able to see far into the distance.

    Woo! This is better than in Lugaru 1, where you can only see about 600 feet into the distance. (Very noticable when you’re flying)

    Thanks for blocking me, by the way.

    Is it too early to ask for a basic demo? Not like a 20-day time trial that shows you all the game features, just a simple physics demonstration, where you can run around in space or something. I’m dying to play at least some part of Lugaru 2.

    Lugaru 2 is not ready enough to really have any kind of demo, but there will be a demo in the next month or two made using the Phoenix engine.

    Sweet! It’ll never leave the doc, guarantee.

    Oh, and edit… I’m guessing the demo doesn’t have any of the texture features you mentioned like multiple variations of the same texture to prevent tiling artifacts or something, the landscape is higher-res than Lugaru 1 but it still looks tiled, I’m betting that’ll change.

    Right, this version has complex texturing disabled to focus on the geometry.

    Well really the polygon count increases only quadratically, not exponentially :P

  8. David - September 29th, 2006 at 1:38 pm

    True :)

    Alright Truce! Truce! Let me back in the forums! I’m sorry I was being an ass before. And don’t tell me that you sent me an email, because my email adress got deleted by accent.

    *accident

    That’s your problem, Macwiggy… PM the admin instead of posting here, please. Anyway, I’m glad that the LOD got extended, because in the first Lugaru, I would wander off and I wouldnt be able to find the main area again… Sad isn’t it?

    The terrain seems to be very blocky and repeated. (like the desktops that come with Mac OS 9) You should work on making them more fluid, solving the age-old problem. Or you could place a S**tload of buldings to cover the terrain, but that would take too long.

  13. David - October 15th, 2006 at 10:18 am

    The terrain *texture* is tiled at high frequency, and I will fix that when I start working on final terrain texturing.

    You should make a small town like in the image at the top of the forums. That would be freaking awesome.

  15. NickD - October 18th, 2006 at 9:21 pm

    GASP! I thought you were making mountains and stuff… or hills… nice job by the way. Especially with the shaders… wait. Are you using shaders with OpenGL? I didn’t know that OpenGL supported shader libraries. Nice job, again! Shaders remind me of Beyond Good and Evil :P (Best PS2 game ever created).

    WOAH! the game looks good plz update more and tell me when it will come out plz

  17. wasb - November 7th, 2006 at 2:04 pm

    by the way how much will it cost?

  18. wasb - November 8th, 2006 at 1:23 pm

    the game looks beutiful!

  19. NovaNoah - September 16th, 2007 at 2:54 pm

    yeah how much will lugaru 2 cost? $20?

  20. Cupcake - November 6th, 2007 at 7:58 pm

    Uh, where’s that demo you said would come out? Would someone please help me find it if it did come out?
