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 !!! |

4)
-- optional -- i like to normalize and convert this to a 16 bit unsigned image fx CODE fx f1=d.hi.cub to=d1.cub equation=((f1-0.440323)/0.119344)*65536 for this image then there are a few ways to take a highpass of this in isis it makes a singed image so i take a few steps run lowpass on it (boxcar 101,101 ) [attachment=21635:Screenshot_9.png] and subtract it from the other in Nip and openev isis.cub to a 32bit tif from openev then use nip to convert the 32 bit tif to a 16 bit tiff you can use whatever programs you are comfortable with but highpass the image or subtract a lowpass in nip invert the low pass and "use nip's "blend" [attachment=21636:Screenshot_10.png] [attachment=21637:Screenshot_11.png] there is still some cosmetic editing yet but it is in very predictable spots the crater rims are a bit low on the top and bottom and the crater is a bit deep on the inside left and right and it has a slight emboss look to it |
