hatrick Posted April 5, 2009 Share Posted April 5, 2009 hi, how can i setup an object following a curve inside a geo hirarchy? i tried to add the pathobject and pos parameters to a xformnode but somehow...? thx Quote Link to comment Share on other sites More sharing options...
edward Posted April 5, 2009 Share Posted April 5, 2009 You have one object that you want to be constrained to the path, or multiple objects? For a single object, you just specify its Path parameter. For multiple objects, it probably easiest to use the FollowCurve IK solver with bones and then use parenting. Quote Link to comment Share on other sites More sharing options...
Ole Posted April 5, 2009 Share Posted April 5, 2009 Do you mean SOP level? (GeoSUBlevel). In that case, I've made a small HDA that will take geometry and constrain it to a curve. You can find it here. Quote Link to comment Share on other sites More sharing options...
hatrick Posted April 5, 2009 Author Share Posted April 5, 2009 great!! thx ole Quote Link to comment Share on other sites More sharing options...
hatrick Posted April 5, 2009 Author Share Posted April 5, 2009 how can i increase the pathfollow value over 1?... in the parametereditor the value is locked. i use a fused l system as path and it works fine but somehow can't get the value higher than 1...

Ole Posted April 5, 2009 Share Posted April 5, 2009 You can change the locked values manually by following these steps: - Right-click on the OLE_FOLLOW_PATH node and select "Type Properties". - Go to the "Parameters" tab and find "Translate along curve" in the list. Remove the locks under "Range". I have only tested it with regular curves and not l-systems. Quote Link to comment Share on other sites More sharing options...
hatrick Posted April 5, 2009 Author Share Posted April 5, 2009 for now i paint in new curves with the l system as reference... i m not shure how to use lsystem parts as splines ore something... your follow SOP works great with standard curves ... thx a lot! cool stuff i ll test the lightdome soon greets Quote Link to comment Share on other sites More sharing options...
hatrick Posted April 8, 2009 Author Share Posted April 8, 2009 in case someone is interested ... i often tried to setup geooutlines ore edges in this case a part of an l system as a path.... one way i found out is to refere a new curve to the geo you wanna build your path with creating the new curvepoints in the coordinatetab of the curveparameters by space-typing the pointnumbers of inputgeometry with a "p" in front. ...

sibarrick Posted April 8, 2009 Share Posted April 8, 2009 In the snap settings turn on consolidate points then when you snap a curve to a piece of geometry it puts a reference to the original point, that gives you the 'p' bit automatically.

SpencerL Posted April 9, 2009 Share Posted April 9, 2009 hi,how can i setup an object following a curve inside a geo hirarchy? i tried to add the pathobject and pos parameters to a xformnode but somehow...? thx maybe Im missing something, but what about just taking curve SOP, add carve SOP > extract point, then copy SOP your geo via obj merge SOP to point from carve SOP.

hatrick Posted April 10, 2009 Author Share Posted April 10, 2009 also a very nice solution thx... Quote Link to comment Share on other sites More sharing options...
hatrick Posted April 10, 2009 Author Share Posted April 10, 2009 certainly the object is not orientated (rotation) alsong its path ... Quote Link to comment Share on other sites More sharing options...
SpencerL Posted April 10, 2009 Share Posted April 10, 2009 certainly the object is not orientated (rotation) alsong its path ... you could use a trail SOP > Compute Velocity and set your Normal to $VX, $VY, $VZ to get it to orient along the path.
