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 !!! |

first the gimp Gmic filter( was called Graystration ) and is also in the CImg.h
this filter is a bit on the "odd "side .It dose things a bit differently than other filters . It uses a PDE for heat flow ( diffy-Q's are fun) http://cimg.sourceforge.net/ http://gmic.sourceforge.net/gimp.shtml and it is a frequency splitting plugin the top layer in the image becomes the LOW ferq. and the bottom layer is the HI freq. [attachment=21575:enw_orig_crop.jpg] [attachment=21573:Screenshot_1.png] [attachment=21574:Screenshot_2.png] i use a setting of 20 for the split but this filter is also causing the chevron strips , so... at the end i need to remove them . then i import that "hipass" into cyclops as to the direction of the light i was doing this ( a bit wrong) [attachment=21576:Screen2.png] now this is working better [attachment=21577:Screen1.png] i really should go and send off a mail to ' Tom SF Haines ' |
