Human_vX posted a topic in General Houdini QuestionsI hope to get the nearest position on a surface or line that is somewhere along the inverse normal, searching in a range of angles (a cone if you will). If this can be done in vex that'd be ideal (I've messed around sop loops and group stuff but that as expected gets very slow). Too aid with the question there is an expertly drawn diagram.
Mohanpugaz posted a topic in General Houdini QuestionsHi Everyone, Basically what Im trying to do is stick some scattered points on road to a tyre object using XYZ dist and prim uv. I am having static and moving tyre then I subtract the point position of one with the other to get the difference in the movement and exported that as @d attribute, Now on the scattered points Im searching the closest primitive of the tyre using XYZdist Then I'm extracting the @d from that primitive using primitiveAttribute VOP (primuv) and add it to the @P of the points . So it get the movement of the tyre. What I get is only the points which are near to the tyre on its initial frame are getting sticked. Can some one please give me an Idea how to do this.. I know we can do this easily with POPs Im doing this only to learn more vex. Thank you in advance.
miccetro posted a topic in Animation & RiggingHi community, I'm trying to use the primuv vex function to move an object along a curve in sops and have it correctly oriented as well. Any ideas? I've attached a hip file. Thanks. obj_along_path_SOPS_01.hip
