loudsubs Posted December 6, 2009 Share Posted December 6, 2009 This probably has a really simple answer, but I'm having a little trouble figuring it out. I'm doing this basic modeling tutorial. About half way down in exercise 3, it tells me to use copy stamping to create the image shown (in the tut). My guess was that it should be done in a transform SOP, where each copy needs to be rotated in increments of 90 degrees, but Im having trouble doing this. If anyone could give me an explanation, it would be much appreciated. Heres the hip file I've been working on.

anim Posted December 6, 2009 Share Posted December 6, 2009 here is the fixed file it's not done by copystamping, since the rotation of individual copies can be done inside Copy SOP with rotate parameters but i have changed the left input geometry si it is centered to 0,0,0 to get correct rotation proc_model_fix.hipnc Quote Link to comment Share on other sites More sharing options...
loudsubs Posted December 7, 2009 Author Share Posted December 7, 2009 Thank you for your help. Did not know about that round expression. Your way is simpler. I actually figured out where I was going wrong. In one of my transforms I had the object offset by -2. Once I put it back to zero, the pattern looked good. In my way to get each piece rotated to 0 or 90 degrees randomly, I used the stamp function in the switch node, to randomly switch between the 2 variations. I used rand($PT) as the variable value in the copystamping. 2 different ways, same great result. Gotta love proceduralism. proc_model.hipnc Quote Link to comment Share on other sites More sharing options...
icelab Posted December 10, 2009 Share Posted December 10, 2009 Loudsubs, If you are interested, I attached my original answers for the students . Yes, proceduralism is fun. Kam exercise_03_finished.hipnc exercise_03_extra.hipnc Quote Link to comment Share on other sites More sharing options...
loudsubs Posted December 14, 2009 Author Share Posted December 14, 2009 Thanks Kam, Im having trouble creeping the newer version with more variations onto a sphere. The pieces that look like a cross are giving me a weird result. All the other pieces of it seem to be creeping fine though. exercise_03_extra.hipnc Quote Link to comment Share on other sites More sharing options...
