Topic: Creating the world
Moving out of the chat where BDA got me back on track...
Here are two pretty high res bump maps of the Earth, one from sea level up (0 to +6400 meters), the other down (-8000 to 0 meters):
My first instinct is to open these in photoshop, use adjustment layers to slide the 0 point to the middle (say RGB=142, which puts zero at roughly the same proportion as the 6400/8000 meter numbers) and then do a color select to grab the below-sea-level stuff and paste it onto the above. Having done this, it seems to create some sharp edges in a few places where I don't think the topography should be very steep. Like the arctic north of Norway & Russia.
If anybody has a few minutes to review my work, I'd appreciate the sanity check.
drewjmore: But this is progress, thanks BDA.
drewjmore: and make some arbitrary decisions about where one map ends and the other begins.
drewjmore: which means I need to shop them together
drewjmore: Argh, seems to be hard to find both the land and the seafloor in the same map.
drewjmore: This might be a good one. https://www.visibleearth.nasa.gov/image … topography
drewjmore: Their stuff is in some odd formats, too. https://solarsystem.nasa.gov/resources/ … -3d-model/
BigDamnArtist: I remember it being a bit of a pain to find when I was looking a cpl years back. But if you google around for CG nasa earth maps it should pop up. Pretty sure they also have the other planets in there too.
drewjmore: I've been to usual places, GIS data and whatnot, but maybe I didn't check NASA specifically. brb
BigDamnArtist: I cant look it up right now, but if you google around NASA has super high res maps available, and I'm pretty sure there was a bump map in there when I was looking.
drewjmore: #4: profit!
drewjmore: Then I tessellate the crap out of it and export to OBJ which I import into Fusion 360.
drewjmore: I've got a pretty low-res map on a globe in Max which looks okay.
drewjmore: *want to
drewjmore: My router-table robot thingy is working well, and I wan tot try making a hollow wooden globe with it.
drewjmore: Anyone know of a good place to find one?
drewjmore: CG assets question: a really good bump map of a topographical earth.
