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 -- top [attachment=21624:Screenshot_2.png] side [attachment=21625:Screenshot_3.png] |
