hatrick Posted February 22, 2010 Share Posted February 22, 2010 Hi, how can i get control of the following... le's say i ve a simple rule with one of the leafvaribles at the end and i want to change the leaf to an another input after 5th generation... prem: A rule1:A=!FF//FFJA after rewriting to 5th generation J should be replaced with.... for example K ?... thx a lot HT Quote Link to comment Share on other sites More sharing options...
mightcouldb1 Posted February 22, 2010 Share Posted February 22, 2010 I would set a rule and some probability for what you are facing. Instead of using J explicitly, you could for example, move J to another variable that looks up the iteration number. Something like this: F=FFFA A: t >= 5 = J After rereading your question I think that you want to switch the geometry itself. If so I don't see why you couldn't have two pieces of geometry put into a switch node, and that plugged into the J leaf. Then use a quick expression to swap them out if the generation count is >= 5. Something like this: if( ch( "../lsystem1/generations" ) >= 5, 1, 0) I would highly recommend buying the L-Systems training from CMIVFX if you haven't already. Also the algorithmic beauty if plants is a good book and its free, there is a pdf somewhere. Good luck! Quote Link to comment Share on other sites More sharing options...
hatrick Posted February 23, 2010 Author Share Posted February 23, 2010 thx for your ideas but i think i ve asked my question the wrong way ....when i setup the switch node all the inputgeometry changes with "gen>=5" ... what i want is the geo "gen<5" staying the same and after the 5th generation another geo should show up... i tried to set this up with different rules with different geoinputs, but that way i'm not getting the animation behavour i want. It should be ... gen1: Branch with leaf gen2: Branch with leaf ... etc. up to gen 5 gen5: Brachn with bloom FFFJFFFJFFFJFFFJFFFK would be perfect i ll checkout the pdf ... thx Quote Link to comment Share on other sites More sharing options...

hatrick Posted February 23, 2010 Author Share Posted February 23, 2010 sorry everthing clear now .... it behaves as you ve stated above : A: t >= 5 = J thx a lot !! k ... still troubles ... i ve setup a little example to show what i mean ... it s kind of logical that there re as many cubes as i ve generations but i only want 1 ! is that possible example: prem: A rule1: A=FFFAX rule2: X:t>=4=J "J" is my cube and i only want 1 cube instead of 4 cubes laying on top of each other after the animation passes gen 4... it would be no problem to set this up with multible rulez as a model .... but how to setup for animation thx Quote Link to comment Share on other sites More sharing options...
hatrick Posted February 23, 2010 Author Share Posted February 23, 2010 k ... still troubles ... i ve setup a little example to show what i mean ... it s kind of logical that there re as many cubes as i ve generations but i only want 1 ! is that possible example: prem: A rule1: A=FFFAX rule2: X:t>=4=J "J" is my cube and i only want 1 cube instead of 4 cubes laying on top of each other after the animation passes gen 4... it would be no problem to set this up with multible rulez as a model .... but how to setup for animation thx why noone is stopping me in this single user loop... i completly missed that the animation does not behave by generation but by rule line !! sorry for that Quote Link to comment Share on other sites More sharing options...
