Earth Bathymetry 4k dds

[Darkmiss]

This is my first real attempt at creating a texture, well basicly just a touchup and conversion.
From a 5k Space-Graphics.com map http://www.space-graphics.com/earth1.htm

Earth Bathymetry 4k DDS and 4k bump map







Download here http://ennui.shatters.net/celestia/files/earth-bathymetry.zip 6mb

Due to the small size of my humble home page, This wil only be available on my web site for a few weeks.
So if anyone would like to add this texure to there own site, feel free

Paul,

Thanks!

However...

I think it's best if people don't edit solarsys.ssc any more. That makes it harder to upgrade to the next release of Celestia, which will contain an all new version of solarsys.ssc containing major revisions.

Don't forget that Celestia v1.3.x looks for SSC files in all the subdirectories within its /extras/ directory.

So I'd suggest that people using this add-on with Celestia v1.3.1pre4 and later create the directory extras/bathy/ containing BATHY.SSC plus the directory extras/bathy/textures/hires/ containing the DDS images.

Does this make sense?

[Darkmiss]

thanks Seldon, not a probrlem
i removed the scc information at the bottom

Paul,

You don't need to delete it completely.
Providing text for the alternate texture definition helps a lot to reduce typing errors and the subsequent frustration.

[ogg]

Is this a good candidate for the new 'alternate surface' feature? Looks like it to me... how is that feature supposed to work, anyway?

[Darkmiss]

Seldon, i didnt even know that textures can be used in the extras directory now. good stuff

i just have this texture next to my earth texture in the medres folder
then i used the "alt texture" entry in my solarsys.ssc

it;ll take time to get used to new ways of doing things

and ogg, in the new 1.3.1 pre 4 if you right click on a planet you can select alternate textures from a drop down list in the context menu

but i think the hows and whys about this should be release soon
it works really well

I can switch between Don's and Toofri's Pluto in seconds now

Ever tried the '+' key? It even produces a little message for free in addition;-)

Bye Fridger

[Darkmiss]

oh yeah i did, but forgot about that
the plus key switches between normal and Limit of knowlege textures

just gets better

[fsgregs]

Darkmiss, your texture witrh bumpmap is great. Just to let you know, I also took the texture and added the "Ring of Fire" to the tectonic boundaries. Here is a screenshot



You can get it at my website: http://www.fsgregs.org/celestia

Enjoy.

Though I havn't yet run it in celestia yet the texture looks great.
Is the ocean floor bumpmapped as well?
Its a perfect candidate for a dying earth which would make a nice companion to Don's terraformed Mars.

I've mirrored it on my sourceforge webspace, ill leave it there indefinitely so you can link to it from your homepage if you wish.

Here is the link.

Paul,

I wrote a description of how I organize my extras directories. It's available at http://www.lns.cornell.edu/~seb/celestia/addon-intro.html

Add-on surface textures still have to be in textures subdirectories, it's just that they don't have to be in the one that comes with Celestia.

[Gordon]

Frank,

i don't see the file in your directory. Which one is it ?

G.

[fsgregs]

Sorry. Its called "Tectonic Earth.zip"

Frank

[Gordon]

Frank,

on your site i see "tectonic earth" which links to http://www.fsgregs.org/celestia/files/tectonicearth.jpg (it's not the one shawn here) but I still don't see the .zip one.

I've created a ZIP of Paul's Earth bathymetry textures along with an AltSurface .ssc and placed it on shatters.net as an example of how to create an alternate surface add-on. You can download it here:
http://www.shatters.net/celestia/files/earth-bathymetry.zip

Here are the contents of the .ssc file:

Code: Select all

AltSurface "bathymetry" "Sol/Earth"
{
    Color [ 0.85 0.85 1.0 ]
    Texture "Earth-Bathymetry.dds"
    BumpMap "Earth-Bump.png"
    BumpHeight 4.0
}


The directory structure I used (and the one that I recommend for all Celestia add-ons) looks like this:

Code: Select all

bathymetry/
    earth-bathymetry.ssc
    textures/
        medres/
            Earth-Bump.png
            Earth-Bathymetry.dds


This way, all that a user has to do to install the add-on is to unzip it in their extras folder.

Let me suggest an alternate method of implementing Frank's tectonic Earth add-on. It would be very easy to combine it with the bathymetry add-on by using Celestia's new OverlayTexture feature. Rather than creating an entirely new texture with the Ring of Fire painted over the Earth bathymetry texture, make a texture which just contains the Ring of Fire and transparent areas where the underlying texture should show through. Then, add another AltSurface to the .ssc:

Code: Select all

AltSurface "tectonic" "Sol/Earth"
{
    Color [ 0.85 0.85 1.0 ]
    Texture "Earth-Bathymetry.dds"
    BumpMap "Earth-Bump.png"
    BumpHeight 4.0
    OverlayTexture "ring-of-fire.png"
}


OverlayTexture was added mostly to implement the limit of knowledge masks, but as you can see there are other uses as well. A political map overlay for Earth is another possibility.

Chris:

These new features just keep getting better and better.

Thanks to you and Fridger and Christophe and everyone for both the Alt textures and overlay features.

Now, if I only knew how to create a transparent ring of fire???

Is the ocean floor bumpmapped as well?

Sorry marc i could only find a standard bump map.

And thanks Chris for putting up the file and code.

You know what'd be really nifty? A map of the Earth showing the bathymetry, but all the map would be coloured brown like the Sahara, with ice caps at the top. Sorta like what Earth would really look like if the oceans weren't there, rather than having the bathymetry bits coloured blue.

I made myself a bathymetry bumpmap from the old ETOPO dataset a few years ago, for another project. It resizes to a 1k Celestia texture. Give me an e-mail address by PM and I'll send it to you, if you want.

You wrote what I am thinking since some time. If I had a bathimetry texture on my hd, I would have done it, just for fun, but my internet connection from home is too slow...
