![]() The wireframes of these breps can be drawn immediately, but the shading meshes need to be calculated first. Let's assume that at some point one or more breps are added to the document. Let's take the meshing of Breps for example. As time goes by we'll probably add multi-threading to more and more algorithms, for Rhino5 we tried to at least make all our algorithms thread-safe, so they can all be called from multiple threads, this is the first step towards multi-threading.īut multi-threading is not just something you switch on or off, it's an approach. Some portions of the runtime code use multiple processors*. * This may change in the future, but not the foreseeable future. Robert McNeel & Associates do not support these Operating Systems. Even if they do, performance is typically pretty bad. Rhino and Grasshopper sometimes run on virtual machines such as Parallels and VMWare, sometimes they don't.NET 4.0 or better while running on Rhino5. Grasshopper does not have heavy traffic to and from the disk.A better graphics card will improve performance here. Grasshopper 3D preview are drawn either in OpenGL or GDI, which are hardware accelerated.Grasshopper framerates are dependent mostly on processor speed. Grasshopper GUI is drawn using GDI+ which is not hardware accelerated. ![]() Some further points to take into account: If all you care about is Rhino and Grasshopper, you'd be better off getting a dual core 2GHz or even a single core at 1.8GHz an 8 core processor that has a total clock-rate of 6GHz will only give you 6/8 = 0.75GHz per core. Do not be bamboozled by advertised processor speeds as those speeds may be given as a sum-total over all cores. But remember that Grasshopper and (most of) Rhino are single-threaded applications* and therefore do not benefit from multiple cores. It is important that you get as much bang for your buck as possible since computational speed is often a bottleneck. Processors are tricky, so pay attention.Do not, under any circumstance, settle for an Intel graphics card. Be sure to get a fairly high-end card from a trusted manufacturer (ATI and NVidia basically). Unless you are running software which specifically uses the GPU for computations (a lot of modern Render engines for example) the only purpose of a video-card is to quickly display pixels on the screen. Graphics cards are important for 3D display, but not much else.I recommend getting at least 8GB of high speed RAM, but if you have money for more, go for it. If you're running 64-bit Windows and a 64-bit version of Rhino, then there's really no upper limit to the amount of RAM you could install. Once you run out of RAM, Windows starts to use the hard-disk as virtual memory and when that happens you can say goodbye to performance. Since Windows itself (and any other applications that are running) require a lot of memory as well, you should make sure that you have sufficient RAM. If you deal with lots of data you need lots of memory to store it in. We have no strict recommendation or requirements, but here are the basic rules when it comes to picking hardware for Rhino and Grasshopper: Although we aim to make our software runnable on low-end, over-the-counter computers, you may still run into serious performance issues. ![]() Implementation: translation from C++ to C# of a centroid for a closed polyline with or without holes: mapbox/polylabel: A fast algorithm for finding the pole of inaccessibility of a polygon ().Grasshopper (and indeed Rhino) can be performance critical applications since both potentially deal with large amounts of data and computations. Also it is faster to nest low resolution polylines, and then apply transformation "T" output to moved detailed objects such as curves to nested shapes. The library is based on Boost 1.62 that is used to compute NFP - No Fit Polygon. The plug-in is located in Grasshopper: Params tab -> Nest Categary. I recommend to decrease tolerance to 0.01 in the main nesting component to achieve precise nesting output even it takes longer to compute. Post all questions on McNeel forum under OpenNest category or write me an email with attached files. dylib and you need to validate this file before use if you get security error.
