I'm trying to extrude a series of polylines with extrusion distance at each point equal to a Hey @konstantin magnus, great solution for the contour lines. add tube node add group node group type: edges include by edges -> enable The Extract Transform Object gets its transform by looking at the points of two SOP geometries. But the point is that in Houdini every simple function requires so many steps, that in the end you get a massive overhead of additional actions that it nullifies any advantages you get from the Lines and Curves (64:25 minutes) This tutorial starts with an explanation of the way Houdini creates curves, and the difference between edges in Houdini and other modelling programs. More specifically a tube with curvature and taper. I think it need to be converted to geometry first. Hi guys, I've created a noise curl effect in Houdini, and trying to export the lines as splines so I can further work with it in 3D Max, any suggestions on how I can do that without giving it This node performs Houdini’s native remeshing operation on partitioned geometry, processing each piece in parallel which greatly reduces the calculation time of traditional remeshing. Even though attribute values are only stored at the points, when you read the attribute at an arbitrary distance along the curve, Houdini interpolates the nearest I'm trying to export 2D vector lines so I can laser cut them.
