The edge for example can be used to build additional geometry. Containment curves have a number of useful applications, for sorting geometry based on its spatial extents.
This Python code extracts the control points of selected curves and associates curves names to extracted control points.Although we are speaking about curves at the moment, it is important to mention two grasshopper that are similar to curves: Rhinoceros (Rhino) is a 3D modelling software specialized for free-form NURBS (non uniform rational B-spline), created by Robert McNeel & Associates. Select your curves (letters, lines, etc, and make sure that the "TOP" view is active.Behold a degree=2 nurbs curve with 3 equally spaced, co-linear control-points: In order to translate the built curve there were a few options to explore. This is how our Plants kil vol 2 is done - you can directly copy blocks that are in the file, so you eliminate the time spent on this process.Follow curve rhino Notes If the objects you are rendering are very complex, Rhino may shade them more slowly than usual the first time. These blocks should be used for scattering. And last thing - Rhino performance - As for now, using Rhinoceros 5 + V-Ray 3.60.03 the most effective way is to convert geometry to proxies and then to blocks. This makes scattering process a bit faster and eliminates the issue with object under the surface.
For the Normal orientation - sometimes it's a good idea to mesh the surfaces you want to use for scattering, check normals of these meshes and join them. Then we have to adjust these accordingly. Regarding the Rhino Grow - we use it all the time, however it needs manual refinement after the scatter is done - Plugin doesn't position objects evenly and leaves empty areas, while at some areas, the population is too dense.
Hi! First of all, Rhino grow will be obsolete in a few weeks - new scattering plugin is under development and it looks very promising.
