Improved 3D Geoscape Rendering [was: Nightime city lights in 3D geoscape]

[H-Hour]

Looks great arisian. I would agree with mattn, thinner borders. Brightness is good. Opaque-ness, I think good but will have to see it in thinner borders.

Also, if you go back to revisit the ocean reflection, I think it should be less bright and cover a larger area on the globe.

[arisian]

First off, yes, you will be able to turn it on/off; it works the same way the nation overlay always has, except that the colored patches for nations now have glowing borders.

And I will work on improving the specularity and adding other rendering features, but that might take me a bit longer to have time for (the nation borders don't actually require much work).

I haven't seen new ufo: ai globe, but check this out:

Maybe this could work as inspiration.

Just a quick status update; here's a couple of screenshots from my latest version.  I've toned down the specularity a bit, and worked on the glow texture.  I've also made some less visible improvements, including making my GLSL code not need so many texture units, reducing memory footprint, and having a proper tangentspace for calculating bump-map lighting.  I'm going to take a look at trying implement post-processing effects like rendered glow (as opposed to "glow" which is actually a hand-painted texture, which is what I've been using up to now).

very nice. please show us your patch - i like small commits

Looks great arisian.

[Bartleby]

that looks very good.
but now the sun also needs a texture .

[BTAxis]

Actually, the sun needs to be done in shaders, probably.

Okay, the patch is posted over at the patchtracker, though I'll post it here as well.  I have to post the texture-images here because the patch-tracker will only accept 256k of attachments.

I've only included one season texture in this tarball; just use symlinks (or copies on windows) to make all the season map names point to this file, or go grab updated versions of all the season textures from http://cs.jhu.edu/~ben/graphics/ufoai/ (the new files aren't there yet, but the links are; the files will be there in a little bit, when I'm done converting/compositing/resizing them all).

Code: [Select]

R_LoadShader: geoscape_fs.glsl: Fragment shader failed to compile with the following errors:
ERROR: 0:46: error(#202) No matching overloaded function found dot
ERROR: 0:59: error(#202) No matching overloaded function found dot

users are reporting this error

[arisian]

Is this error only with the newest patch, or with any version of the GLSL shaders?  Can you post any info about their graphics cards?  It works fine for me, so it's a little difficult to debug; I suppose it might be some sort of difference between what version of GLSL their cards support, though I thought the dot product operator was always available.

bayo fixed it in current trunk: https://sourceforge.net/apps/trac/ufoai/changeset/29155

[arisian]

Okay, I'm glad it got fixed.  I started trying to fix something else, and got bogged down; I'm having trouble fixing specularity properly because things like vertex and light positions don't seem to be relative to view coordinates, or the view isn't where it should be, or something.  Anyway, I'll let you know when I get it figured out; I suspect it's an issue that's being caused by the fact that we're not using a projective system, which means the "view location" doesn't have the same meaning it normally would.

[Mattn]

can you please attach the textures? (those that are missing in the patch https://sourceforge.net/tracker/?func=detail&aid=2977653&group_id=157793&atid=805244
