peliosis Posted September 13, 2005 Share Posted September 13, 2005 I've just have a chat with my friend who is going to animate a domino like structure of falling pillars in 3dsmax. After giving him an advice to learn some basic scripting, I smiled and thought how easy should it be in houdini. A quater later I started fighting with it, and haven't found a nice solution yet. I tried to make a sop domino with elements copied along user given path. I'm a bit stuck with controlling (here offseting) the animation of each stone independently. Apart from my own problems with the subject, perhaps it is an interesting challenge? Does anybody have an efficient domino technique?

jjstanley Posted September 13, 2005 Share Posted September 13, 2005 I would start with rigid body DOPs. It should be very easy. Quote Link to comment Share on other sites More sharing options...

edward Posted September 13, 2005 Share Posted September 13, 2005 Can't you just use copy/stamping and then rotate the blocks depending on $F? Quote Link to comment Share on other sites More sharing options...
stu Posted September 13, 2005 Share Posted September 13, 2005 Yes, but where's the fun in that? Quote Link to comment Share on other sites More sharing options...
edward Posted September 14, 2005 Share Posted September 14, 2005 Oh, alright. An RBD solution then which has the advantage of being more realistic. dominoes.hip.gz Quote Link to comment Share on other sites More sharing options...
George Posted September 14, 2005 Share Posted September 14, 2005 Here's something I did a while ago after seeing Robots. It's somewhat manual, it's somewhat slow, it collides all over the place and frankly it's a hack -- but it only uses expressions and copy stamping Hope that helps.

This is a very special day - today is the first time that I've known e.d. to acknowledge the aesthetic benefits of one solution over another. :shocking: Quote Link to comment Share on other sites More sharing options...
deecue Posted September 14, 2005 Share Posted September 14, 2005 those are some sexy expressions there george.. nice work :notworthy: Quote Link to comment Share on other sites More sharing options...
peliosis Posted September 14, 2005 Author Share Posted September 14, 2005 Great examples, thanks. I haven't play with dops yet just because houdini is so deep, but they seem to be quite slow with these settings? I was thinking rather about something like george's technique. Nice expression tutorial I thought about a chop technique - using a shift chop and stamping start value based on $PT, but it doesn't seem to work??? I submited a topic on sidefx forum, but nobody answered, do you have any clues? Quote Link to comment Share on other sites More sharing options...
peliosis Posted September 14, 2005 Author Share Posted September 14, 2005 Ok, as usual, that was simple and required looking into the help. I thought I knew how to use copy sop:) So here is my clue solution. "Stamping parameters let you communicate information upstream to the operators connected to its inputs." Ahhh, I just began to wonder about the possibilities of stamping chop parameters:( Quote Link to comment Share on other sites More sharing options...
Visual Cortex Lab Posted September 15, 2005 Share Posted September 15, 2005 sorry for the lame question but... is the copy SOP the only able to let us use the power of stamping? cheers Quote Link to comment Share on other sites More sharing options...
sibarrick Posted September 15, 2005 Share Posted September 15, 2005 the only sop, yes. Quote Link to comment Share on other sites More sharing options...
edward Posted September 15, 2005 Share Posted September 15, 2005 I think the LSystem SOP does stamping too. Quote Link to comment Share on other sites More sharing options...
deecue Posted September 15, 2005 Share Posted September 15, 2005 yea, l-system can do it too but i think only for the leaf inputs (not meta).. Quote Link to comment Share on other sites More sharing options...
