closeup earth map
show user profile  ale calonge
Hi everybody. Sorry to bother you. I need help with a problem.
I have to model a planet, an earth with super high res definition. I used a vector political map of the world, I converted it to TIF in hi res, and I put it in a sphere in max. BUT the closeup i sooo close that the border of the map are jagged.
I have two possibilitties to consideration:

* Use the vector file (illustrator AI) as a texture. (Is that possible?)
* Or make an extrude object of that AI spline, but afterwards HOW I WRAP IT AROUND THE SPHERE?

Thanks a lot in advance for your help and your time.

You can rasterize your vector image to an even higher resolution.

Either convert the image to a higher resolution as garp says, or keep the map detail as polygons & overlay that into the sphere geometry - will be a fair amount of work creating the polygonal overlay but might be worth the effort. You'd need to ensure you don't have overlappoing polys between the sphere surface & the overlay to prevent z-buffering artifacts when viewed from a distance. Either that or composite the land area over the top in post.

Depends what you're trying to do.
You can either overlay the sphere with a high resolution texture or build the detail into the geometry. or both.

Thanks guys. I tried with a resolution of 600 dpi in 10000 X10000 and it worked.
Thanks again.
