Comment on: Topic 'Shortest Walk Tapered Branching Script'

the code by double clicking to see the Python.I separated boundary (clipped) Voronoi cells from interior ones.It's fast enough that with the Voronoi and Tet mesh output switches toggled off you still get tetrahedral points and lines for previews as you work. Even with Tet mesh output on, it's still plenty rapid.The mesh must be fully triangulated, or my STL writer will output each quad as only a triangle and an open triangle and who knows what Tetgen will do with holes.Deviled Voronoi are now possible:The internal -q Tetgen command line flag in the Python can allow the tetrahedra to be more extreme in sharp angles to allow them to grow bigger away from the boundary, or at least part of them, as they retain a sharp pointy corner towards the boundary.The point of all this is to escape from the ugliness of random 3D point Voronoi in favor of evenly distributed 3D points, with boundary mesh control over the surface cells that then transition smoothly to the interior.Tetgen.exe pre-compiled binaries for Windows X32 and X64:https://github.com/JuliaGeometry/tetgen.dependency…

Comment on: Topic 'Box Morph Trapezoidal Blocks onto tower faces'

lane.WorldXY when making "parts" ... especially if these are used for defining instance definitions (blocks in plain English).Notify if you need the proper/"pro" way to do that using ONE object transformed N times instead of cloning the object (the "window frame") N times: this is what the Orient component does and this is the reason that is so slow (Blocks boost performance by a factor of 100 making the def almost a "real-time" one). Note: Morph Methods work only against Geometry Base types ... thus this approach is useless when non linear transformations are in the pipe line.Notify if you need a "variation" for twisted towers (there ... the disabled Morph component MAY serve the scope [but it's the totally wrong way to do it in real-life]).This:is a rather "compact" way to "skip" randomly items from trees (whilst maintaining the structure: examine the paths ...... AFTER the massacre to see it in action ["some" paths are MIA, he he]). The components that you've mention work on Lists.This:does some things not available as native components.…

rimitive way to do business) imposes serious limitations with regard the topology of the line graph on duty. I do hope that you understand what I'm talking about. DO NOT use this attached against graphs made via proximity 3d and the likes.2. No clash detection (via trigonometry) is included. Either instance definitions.3. No values check function is included: this is a rather complex thing when we do real-life "geodetic" trusses.4. For the critical part: the linkage ... well you have 3 choices (see comments inside). Modelling a parametric linkage in GH/Rhino is 100% out of question. The only thing that you can do is use one as instance definition and put it in a myriad of places. DO NOT attempt to do that the classic way (Orient component).5. Go to the model shops ask for a big radio controlled car/buggy and observe what a mini ball pivot linkage is (the red freaky thingy): May the Force (the dark option) be with you.Suggestion: abandon ship.best, Lord of Darkness…

Comment on: Topic 'Grab Group of Branches from Tree'

in degrees. So at 1, all lines increase by 1° as they move in x.I wanted to have multiple "panels" of lines, and be able to increase or decrease the number of panels.Something like this:I actually made a previous thread about this, and a very kind man suggested evaluating the curves instead of dividing, but that pretty much changed the whole definition.Easy solution, copy the whole definition by the nr of panels desired and change the angle slider on each one.So I though about a series of numbers. That gives me control over the nr of panels, and also the inclination or the angle these lines will have.So right now, I have 20 curves, all divided by x, that gives me 20 lists of points and then I connect all these lists to A. B are just points on xy plane.If I had multiple values inputted into the division component, and could grab the 20 lists of points that were generated after dividing by 1°, and by 2° and by 3°, etc. I could connect all those lists to A in the line component.…

Comment on: Topic 'How do I decompose 2 intersecting surfaces then recompose as 1?'

things I need to keep in mind are that, 1) I'm the only tool guy on this project, and 2) I need to generate results in my application domain - and Rhino, Grasshopper and my own code are tools, not results. If I spend all my time developing tools (or learning how to develop tools) then we're never going to get across the finish line. I can perhaps take a longer view on my tool investment once I have the "core" functionality in place. But I'm not there yet.I've mapped out the various algorithms I would use for each task of the toolset I'm developing. For example merging surfaces was supposed to simply involve intersection/split/cull/join. That intersection operations don't always return complete, accurate and usable results throws my plans into the air. Data flow programming of genetic algorithms fits my background of 30 years programming and 5 years of 3D design. Diving more deeply into the underlying math of B-rep geometry is a rabbit hole I didn't budget falling into.You bring up other architectures like solid modeling and features. R/GH are just 2 of many, many tools I've looked at to achieve my goals. No single tool or ecosystem looks complete enough to meet all my needs. My prior stop on my quest was OnShape. I found much to appreciate there, but it's still VERY early in their development. (I personally think they are a decade away from having a solution worth investing in.) R/GH seems fairly mature, but I'm already hitting walls like this. There are always struggles and never an ideal solution.Thanks for your insights,- Bob…

Comment on: Topic 'Principal curvature lines on surfaces: need some advice please'

ines of curvature on meshes, but the CF approach is more general.The only thing that is not clear to me is how you handle closed curvature lines with this kind of integration scheme. This rarely occurs for negatively curved surfaces, but it is a common feature of positively curved surfaces that we are used to build (think of domes, like ellipsoids). Without proper closing condition, you will get a spiraling curve instead of a close one (because of all the small errors accumulated during integration).Regarding integration techniques, you can pick Verlet, RK, Euler, but I have the feeling that in the end, they have similar limitations (you can find a benchmark herefor example). For NURBS, it might be possible to find some analytical formula for PC (it's very tricky though).An interesting case is when you describe you shape with cyclidic nets. Instead of control points, you have a coarse circular mesh, and it is then possible to generate a NURBS patch parametrised by its lines of curvature, so that the UV mesh follows a PC-Line network. This field has been investigated by the team of Alexander Bobenko and also by Helmutt Pottmann (and proposed decades before by Ralph Martin).Best,Romain…

Comment on: Topic 'Mesh From Lines'

ts is small you end up with an overlap of the cylindrical arms of the nodes...I had help fromDavid Stasiuk dealing with this as his exoskeleton plugin has a method of calculating the distance from the node corner to the base of each cylindrical arm such that the arms do not intersect.Attached is a sort of version of exoskeleton using GH components and within it you can see how he calculates the distance required to avoid overlapping arms. This was pushing the limits of my GH abilities just to try and understand it!I've been re-visiting this topic for years now. My goal was to design nodes for line structures that I could actually make (I also want panes of glass in my structure though) My original idea was to 3d print the nodes. Although you can print the nodes you have designed, they are hard to print on a cheap 3d printer as the entire node needs support material. Also, strength becomes an issue unless you can afford to print in metal! I went dow the route of using square section struts so i could potentially CNC machine the nodes on my CNC router but it turns out it would require many jigs and fixtures per node unles I had a 5-axis machine!I'll build that Geodesic Dome with glass panes one day though! :)…

Comment on: Topic 'Louver - rotation'

legant) weed wacking, including duplicate components and curve direction flipping to pull it off. The results look pretty good?Might try going back to full length louvers? I have to wonder, though, if long twisted rigid louvers are practical? Reminds me of America's Cup wing sails, where twist is accomplished by incremental rotation of flexible elements - and there, the axis of rotation is a straight line (actually, a series of four straight lines), not a curve like these louvers.…

Comment on: Topic 'Custom Unit Cell Bug in IntraLattice Plug-In'

(and thus Python) with a selected script as an argument. It uses OBJ files, which are ASCII so I can write them easily with Python. Usually you then have to invoke a button though, but I think an 'if' statement that is always true will also do.The ZBrush rapid remeshing is a form of Boolean union that Rhino will simply not do, let alone fast. But also, crucially, now that I'm playing with IntraLattice custom unit cells, I realize that some interesting curved wire cells not only won't work for existing IntraLattice, but won't work in principle because they smoothly merge into hubs via fattened strut *overlap*.ZBrush in few seconds:You cannot find this performance in open source code out there, code that works, that you can make easy for a client or a coworker to install in a few minutes. This quality of code is in programs and is often a trade secret, let alone possibly patented instead of open source.…
