markerline Posted August 16, 2005 Share Posted August 16, 2005 Dear users: I'm trying to create a lightbulb-like form but I'm having trouble with the last part of the join operation. I have 2 cut spheres and the filleted surface between them. Now, I want to join all three surfaces to make one surface but I'm getting flipping geometry and I can't seem to solve this. Can anyone help? -penciline P.S. I have attached a Houdini 8 Beta hipnc.zip file lightbulb_fillet.zip Quote Link to comment Share on other sites More sharing options...

markerline Posted August 17, 2005 Author Share Posted August 17, 2005 Hi penciline, please take a look at this file. 20581[/snapback] Thanks for that. I d/l'ed your file and looked at it. I tried to replicate what was going on but got snagged where you had your edit SOP. I applied a Transform and got a filpped geometry. I'm not sure what the heck I'm doing wrong but maybe there's a principle that I'm missing. Why did you have to scale everything to -1 in the edit SOP? stuck, -penciline Quote Link to comment Share on other sites More sharing options...
DaJuice Posted August 17, 2005 Share Posted August 17, 2005 Hey penciline, what I did in the Edit SOP was I basically mirrored that half instead of rotating it 180 degrees, which will give you different results as you can see. To be honest I don't think the NURBS tools in Houdini are very intuitive or robust, so I avoid them mostly. Quote Link to comment Share on other sites More sharing options...

The tools may not be as intuitive as one would wish, but they are powerful once you get a hang of them. You have a better control over them than I do, but I see the potential of the tools already. I've worked a little over the fillet and bridge tools and find myself improving. But I already find the Carve SOP/Refine SOP and CurveClay SOP extraordinary tools. They make the job of editing geometry much easier than other softwares that I've dealt with (but I've only dealt with one other I should add). -penciline Quote Link to comment Share on other sites More sharing options...
Jason Posted August 18, 2005 Share Posted August 18, 2005 I like the NURBS tools in Houdini, but they do need a lot of precision stuff fixed - especially when it comes to projections and trims. Multiple trims and especially trims which overlap or cross patch boundaries are a bit of a pain. Perhaps some day they'll revise them and I won't be afraid of them for larger models. We use NURBs for utility purposes - good parameterization is hard to find these days - but seldom for direct rendering unless they're simple models that dont have fillets, trims and whatnot.

edward Posted August 19, 2005 Share Posted August 19, 2005 Thanks for posting! It's always nice to see the hip file of an "old hand". I like how your network is efficient and detailed! Quote Link to comment Share on other sites More sharing options...
stu Posted August 19, 2005 Share Posted August 19, 2005 Thanks - I cleaned it up a bit before I posted it. I got rid of things like trace SOPs ( I grabbed a picture from the net and used it's sillouette as a guide) and about a hundred circle and line SOPs that I used as drawing guides for the curve SOPs that you see there; basically anything that wasn't actually contributing to the final model.

TheUsualAlex Posted August 19, 2005 Share Posted August 19, 2005 huh. That's interesting. I didn't realize that Join SOP works for poly too. the whole time I thought it only works in NURBS. Aaaah. The good o' days. : ) Quote Link to comment Share on other sites More sharing options...
Visual Cortex Lab Posted August 20, 2005 Share Posted August 20, 2005 Sheesh...here you go, your majesty. lightbulb_hip.zip 20683[/snapback] I must admit i've been impressed by the network ... i mean .. the concept is so simple... this makes me really love this program any days even more... many thanks for your post, I'd like to see how you guys who rocks with Houdini work on some "day by day" modeling stuffs... since I'm trying to learn the overall program but at the end... what I miss is the *real* procedural approach for *simple* stuffs like such a lightbulb... THANKS again for sharing that. I've been studying it for over an hour (not that's hard but its been really interesting watching step by step and analyzing it deeply).. and its 4am here now is there any *monthly challenge* on this forum?.. I j ust saw the "trees planet" which has been really nice to see the results. it'd be really cool (and precious reference for newbie like me) to see how good people works and solve apparently easy tasks... i'd like to partecipate as well once i'll be able to. cheers!
