So that i do not take over his nice thread i figured i would start a new one
I am just figuring it out so bear with me
Rhea
This is a example - very early example
http://www.shatters.net/forum/viewtopic.php?f=5&t=15847

one that i am going to redo .
the program i am using "Cyclops" has a few bugs

Enceladus
this is a good example a bit better than the above



the close ups are a 8k level 3 VT with and without a texture over it
then a 4k level2 vt

unfortunately i still have to figure out a bug .I need to run a highpass on it ( the 32 bit isis dem )
Cyclops exports to a 3d *.ply this is easy to export to a isis cub
and i get this ( this happens when i combine 16 smaller images into one big one )
and this example is at 1/2 size


Just a bit of a bug !!!

a bit of a change - the below will create a "good looking" bump image BUT NOT one that is scientifically accurate

someone i look up to - who dose very good work is having a bit of a problem
{ this reminds me - i still need to mail the creator of the program - for some advice}
cyclops is a bit of some "odd" software and i am doing something with it that it was not 100% meant to do
and to solve one problem i am adding another problem .
-- a bit of my background --
10+ years in the photo darkroom doing pro and fine art photofinishing ( i see things a bit differently than others )
then add to it about 10 years on the computer learning "image restoration " and "inpainting" software
- do not get me started on "csi and ncis" shows

--------------------
a tutorial over the next few posts
-------------------
i will start with a dem i posted last night
i am using a crop of N1514126616_1.img ( pds - dione )
[attachment=21621:test.png]
something familiar

1)
there is a bug in using and building cyclops using very new OS
i think it is in glib or libIl( now DevIl ) . But i have not tract it down
it DOSE build on RHEL 5 just fine ( well i use CentOS 5.4 )
for some reason it tosses a "can not open image " on very new os's ( arch and fedora,and i am told Ubuntu also)

i have ran into problems like this before so that is why i have Cent installed along with Arch ( stereo pipline ( isis3) also dose not run in Arch ,but dose work fine in CentOS 5.4
-- so i will go and boot into cent and finish this part

as you can see in the crop above there is some lighting caused by the moons spherical shape ( low res image / wide angle )
the sun is to the left about centered
[attachment=21622:Screenshot.png]

i am using h&w2 ( seams to work the best for this )
the settings i am using are in the screenshot
-- run it --
[attachment=21623:Screenshot_1.png]

this is a normal map ( most will see that )
now there is a LOT of curvature in this image
-- for show in blender --
