Nerox Posted July 25, 2008 Share Posted July 25, 2008 Again I have another, probably, interesting question Can I move every mesh point of an object along its normal? Due to scale without point distance variation. I'm building a Feather system, and I have some colliding issues. So I was thinking to copy the original mesh, scale this down a little, and copy the feathers to it. Having the original mesh serving purely as a visual dummy. But if you scale an object from the center of the object the distance between the new and previous point location may vary. That's not what I want so I hope I'm able to move every point along it normal (in negative) for an X distance. I'm pretty sure I need an point Sop, and some how orientate the point translaten axis to it's normal, but that's where I get stuck. Hope any one can give me a little tip.

MIguel P Posted July 25, 2008 Share Posted July 25, 2008 Great, thanks! Or if you want more control, like offset only some areas, you can use a Point SOP and write $TX+$NX*... in each position field. Quote Link to comment Share on other sites More sharing options...
Jason Posted July 26, 2008 Share Posted July 26, 2008 Tnx! exactly what I initially was looking for . And a nice addition my current setup.More and more I'm getting familiar with the process of creating/modifing/using of attributes, extremely helpful. I'll never go back to Maya . I used to work for a Autodesk reseller, back then I was totally pro Autodesk due to several brainwash sessions . So from my opinion it's quite a achievement that Houdini totally blow me away and made me willing never to go back. Good to hear it! You could also use a VOP SOP, and inside that use a "Displace Along Normal VOP" and wire up the outputs. VEX/VOPs is a whole new playground for you too then. Take care, Jason Quote Link to comment Share on other sites More sharing options...

They should give me an basic/interm look at Vex, really can't wait. I've tried some minor things using vex but I couldn't get anything usefull out of it, due to my 'unknowingness' of the nodes functions. Time will cover that, I assume.
