Tatsu Posted March 26, 2008 Share Posted March 26, 2008 (edited) Hey everyone. I know this challenge is almost over but I literally just started learning Houdini this past weekend and this looked like a good opportunity to see what I've learned so far. Then I hit a stumbling block right off the bat. So... what I've done is ran a 2 segment line through a sweep on a resampled curve, skinned it and made a selection of the points running down the middle for the template of the copy sop. I've added a slight Y rotation in the copy SOP to get the overlap I want but I can't figure out why the cards are twisting as the path moves up and down. Any ideas? I don't know if anyone will be able to open the attached .hipnc. It is of course made with the Apprentice version. cards.hipnc EDIT: Well about five minutes after posting this, I realized I could do what I wanted without the copy SOP. Just sweeping the card itself along curves now. I don't know if this affects how easy it will be to animate later down the line. But I guess I'll figure that out some other time.

Tatsu Posted March 26, 2008 Author Share Posted March 26, 2008 Progress so far tonight.... Might try and figure out how to get some texture on it and get rid of the shading errors tomorrow. Quote Link to comment Share on other sites More sharing options...
bealobo Posted March 27, 2008 Share Posted March 27, 2008 Hello Tatsu, that's looking very good. The twisting of the cards might have to do with the input of the copy sop, as you need a normal direction and an upper vector (you can add this with a point SOP before copying). I was making the same technique, like using sweep instead of copy, but then I saw the marhazan file (the one SWANN cleaned) and he actually uses both, so he has adventages of both sops. I really liked it, I recommend you to have a look at it. Quote Link to comment Share on other sites More sharing options...
Tatsu Posted March 28, 2008 Author Share Posted March 28, 2008 (edited) Thanks for the comments. I had tried the copy SOP but had a hard time manipulating the normals and up vectors to get the layout I wanted so for now its almost all sweeps. I do realize that this makes it much more difficult to randomize things and probably animate as well. However, I know very little about surfacing and rendering in Houdini as of yet so I can tackle that stuff later. As it is, it took me quite some time just to get a properly shaded surface. I must say, even with such a simple scene and very simple lighting, I love the look of the mantra renderer. cards_V03.hipnc Edited March 28, 2008 by Tatsu Quote Link to comment Share on other sites More sharing options...
Tatsu Posted March 29, 2008 Author Share Posted March 29, 2008 And I guess will call this one final. I'm sure everything in the scene is a bit clunky in it's execution. cards_V04.hipnc Quote Link to comment Share on other sites More sharing options...
maharzan Posted March 29, 2008 Share Posted March 29, 2008 Looks really nice and you did it fast. The cards looks bit straight. How about putting a little bend on to it so it looks more natural. I love the sea.. good work mate! Quote Link to comment Share on other sites More sharing options...
bealobo Posted March 31, 2008 Share Posted March 31, 2008 I agree with maharzan, you were fast and it looks very nice! Quote Link to comment Share on other sites More sharing options...
Tatsu Posted March 31, 2008 Author Share Posted March 31, 2008 Thanks everyone. Hopefully I'll revisit this later when I know more about the program. I'm pretty sure the was its constructed now would seriously hamper any attempts to animate it coming together.... Quote Link to comment Share on other sites More sharing options...
eetu Posted March 31, 2008 Share Posted March 31, 2008 Yea, that was quick. i especially like the water eetu. Quote Link to comment Share on other sites More sharing options...
stevenong Posted March 31, 2008 Share Posted March 31, 2008 It looks good. I like the water bit. Also, I feel the arch could be made out of smaller cards than one big card. Cheers! steven Quote Link to comment Share on other sites More sharing options...
