Bumpmap/Normalmap for the Moon
Posted: 03.12.2003, 08:20
I made this several months ago as an experiment and completely forgot about it. As I posted in the 16k Moon texture thread I used Photoshop to manipulate the RGB layers of a 4k Moon texture in the attempt to create a workable bumpmap. Of course no matter how much I played with the thing there were problems with some craters turning into mounds and the impact rays from Tyco kept coming in as long narrow mountain ranges witch they are not of course. So I figured the best thing to do was to do it by hand. So I chose the darkest gray in the texture and proceeded to paint in the crater bottoms and use slightly lighter grays the nock down Tyco's blast rays. In the end the outcome was ok as far as I was concerned. Then I went onto something else it stayed forgotten.
Now when I started to go through that 60+ gigs of Celestia textures and installs I stumbled across it and thought I would load it up with Praesepe's 16k Moon texture. Well it looked a little better than I remembered. So here we are. I am going to post it for download in the next few days as both a bumpmap and a .dds normalmap. Again the size is only 4k so if you are looking from a distance its looks rather nice. But get to close and it falls apart. I might consider doing an 8k version or I can put the pieces together and turn it over to someone else to do with full instructions on what I did.
So as always here are a few pictures. The first is actually a glitch in which the texture didn't load but the bumpmap did. It shows off the detail of the map pretty good. Now I am attempting to use a thumb-nail system to cut down on load times. So click the picture for the full size version.
The second is of an 8k Moon texture, I don't remember who’s at this point, I think it might be John Van Vliet’s but I am not sure, with the normalmap on. Sorry Praesepe but I just couldn't get a good pic with your Moon texture as it is kind of on the dark side. Enjoy
Ooo! looks like the thumb-nails are working! So from now on expect thumbs-nails from me in most if not all my posts.
Thanks for the code Seldon.
