sirogi 1 Report post Posted July 18, 2002 another challenge.... the spec: come up with a system that would allow to plant trees (or whatever) on any surface, and use an offset control surface to define the scale of the objects....it would allow for interactive and procedural modelling, shaping the control surface would impact the copied obj... (hint, whenever the control surface intersects and goes below the base surf, the trees should disappear....) it would be nice if it was robust enough to plug any poly surface as a support surface and still work... erm...in confusion, look at the pics have fun!

TheUsualAlex 4 Report post Posted July 20, 2002 oops...i forgot something Nice work. I got it to work on a flat plane, but I am still trying to figure out how to kill the cones that's facing the opposite direction on the sphere. Share this post Link to post Share on other sites
sirogi 1 Report post Posted July 20, 2002 nice! well done! I just realized, comapring your pics to mine, that there is a hint hidden in my pictures! he he he... erm....intentionally...of...course Actually your solution is more interesting because you use a lower-res mesh to control a high-res template!.... one tiny thing, try to fit the trees to exactly match the distance between the base and the control surf (ie: trunks at the base and peaks at the control surf)...but at this stage it's an nitpick! Cool man, well done! guess we'll wait for a couple more posts before sharing the joy.. c'mon guys! Share this post Link to post Share on other sites
Jason 121 Report post Posted July 20, 2002 hi all, varying rez template, 1 very simple expression. mine'd be simpler but mine culls the trees of zero height - (which are obviously invisible anyway) Share this post Link to post Share on other sites
TheUsualAlex 4 Report post Posted July 20, 2002 varying rez template, 1 very simple expression. Gees, Jason. You always come up with something more elegant, don't cha? Share this post Link to post Share on other sites
AndrewVK 0 Report post Posted July 20, 2002 oops i did it again.... "distance bug" was fixed:) Nurbs,Poly and 2 Primitive was used at once as a "Gardener" Share this post Link to post Share on other sites

TheUsualAlex 4 Report post Posted July 21, 2002 THis is all I have for now. My expression is anything but elegant. Share this post Link to post Share on other sites
Jason 121 Report post Posted July 21, 2002 Thats not bad at all, well done. I see your trees scale only in y, not uniformly like the rest of ours. (An easy fix) Unless we get another entry (DaJuice?betty?), we're almost ready to present our solutions. What do you think? J Share this post Link to post Share on other sites
TheUsualAlex 4 Report post Posted July 21, 2002 Aieek... Please give us a few more days. I am still trying to figure out a different and more effective solution than I already have (which was more of a hack than a solution)... Share this post Link to post Share on other sites
anakin78z 0 Report post Posted July 21, 2002 EEk. Well, my solution seems to work, but I'm not really happy with it. Cheers, Jens Share this post Link to post Share on other sites
DaJuice 25 Report post Posted July 21, 2002 No entry from me, the monitor on my workstation is dead, so I can't do any 3d for a while. I don't think I'd figure it out anyways. I'm a total noob compared to everyone else here when it comes to the meat of Houdini. Gotta hit those tutorials. Share this post Link to post Share on other sites
TheUsualAlex 4 Report post Posted July 21, 2002 I think I figured it out... Half way. However, I am not all that excited with what I have so far... I still need to figure out a much more effective solution than what I have. NEway, can't wait to see what you have, Jason. Share this post Link to post Share on other sites
