pclaes Posted April 6, 2008 Share Posted April 6, 2008 Hi, I am trying to use the lattice sop to deform an object which has a higher complexity: In the example I attached I have a box with some extrusions. A sphere is used in combination with the lattice sop. The sphere feeds into the rest input of the lattice. The lattice sop is used in point mode. Another branch of the sphere is being transformed (just a rotation) and fed into the transforming geometry of the lattice sop. (if you switch it to the dynamics then you can see the problem as well as soon as the sphere rotates a bit). It seems the lattice sop does not handle rotating transform geometry very well. My goal is to get a result similar to Maya's wrap deformer. Is the lattice sop the right approach? Or should I try something else, I have no experience with capturing geometry with metaballs, but perhaps that is a better way? Thank you! lattice_rotational_problem_01.hip Quote Link to comment Share on other sites More sharing options...
edward Posted April 6, 2008 Share Posted April 6, 2008 Try out Simon Barrick's wrap deformer: http://www.fourthwall.ndo.co.uk/HT_HDK_WrapDeformer.html His Houdini tools website: http://www.houdinitools.com/ Quote Link to comment Share on other sites More sharing options...
pclaes Posted April 8, 2008 Author Share Posted April 8, 2008 Hmm, thanks for the suggestion. I am currently under linux :s. I will try it out on a windows machine and see if it works and then try compiling it. Is there absolutely no other way? I just find it so strange that the lattice sop works fine with rotations when it is used in lattice mode and that it gives me these skewed results when used in point mode.

sibarrick Posted April 8, 2008 Share Posted April 8, 2008 If you are on Linux you should be able to compile it for yourself (not that I know how, but someone on here will if you ask) Also there's an otl written in vex that doesn't need compiling kicking around on exchange too. I should probably knock up a python one sometime as well since this seems like a popular thing. Anyone reading this who uses these methods a lot should email support at sidefx and put in an rfe for this functionality to be added. Its actually a very simple sop to write, I recently upgraded mine so it would work with the attributeReorient sop so that makes it even easier. It wouldn't take them more than a day to add it...

pclaes Posted April 8, 2008 Author Share Posted April 8, 2008 Hi Simon, Thank you for your advice. I am currently using your Skin Wrap otl from the exchange. I will send an email to sidefx to include this as I do believe that is very usefull functionality. It seems to run fast enough as an otl for my purposes. thanks again.
