Generating Land Textures...

        Since it is hard to visualize what we have so far.. I will email
anyone who asks, a 500X500 resolution JPEG containing 4 screen shots of the
land in both 3D and 2D forms.  The 207kb file is Sitted and BinHexed on a
Mac.  Those useing PC's wishing to decode the file and who do not have
Stuffit Expander, please specify what you have in terms of unstuffing
programs and I'll see what I can do.  :)
        With these screen shots you will be able to immediately notice
the texture's generic and 'clay like' look, that we would eventualy wish to
avoid.  Any ideas would be greatly appreciated.  :)
Thanks!

You may mail the  500X500 resolution JPEG's to me if you still
have the problem, so we can continue the conversation. Is the 500x500
pixels, meters, kilometers or what?

I'm working on the same problem and would like to hear more from you.
I have also made a program that takes as input Delauney triangulated
data and outputs a texture maps.  To get a more realistic texture you
can use (in addition to just the height) the angle of the plane that
the point is lying in.  You can also use a random generator to get a
more varying texture - that is, low-lands are green but not always the
same green color.

I have some other ideas also.  What I would like to hear from you
(and others) are how you generated the shadows.  And, yes I would like
the image you have generated.

1. Any one know where I can find various sky pictures and land textures

I need several different backgrounds and textures for my images and I am looking for sky backgrounds and land textures. Please drop me some e-mail if you know of any place
that I can get these. Thanks
