Obligatory disclaimer: the author does not guarantee that these parametric models are bug-free or that they will solve all of your problems. It’s a pretty basic script using Python and Rhinoscript, so it can be edited and improved. Here is a working copy of the Vray Proxy Scatter for GH. Enjoy the new Color Assistant to select a color with the right hue and saturation.
Proxies vray rhino update#
Update: Just found some spare time to get this out. Update 2 makes it easier to manage proxy assets and materials. We can now create scenes with millions of polygons and still have parametric control within Grasshopper, so we’re pretty excited about that. These may be tall orders, so we’ll put them on the wish list for now. It would also be really helpful to vary material properties for each proxy instance. If proxies were compatible with something like the ApplyMeshUVN command, we could easily use them to panelize a morphed surface within Grasshopper. Also, the proxy broke when more complex mesh transformations were applied to it (those outside of scale, rotate, and move). For example, if we could find a way of connecting modeled proxies between VRay for Rhino and VRay for 3ds Max, we would have a lot more control and flexibility in our vis work. We realize this ability in VRay for Rhino is brand new, but would like to see more features in future versions. This enables more robust digital models without the lag. A modular system, ranging anywhere from a spider joint to the Cleveland Med Mart panels, can be navigated and edited much more quickly by using proxies as placeholders. While proxy scattering is a powerful tool for creating forests and soup can sculptures, it can also be implemented for visualization of architectural components. Although not quite as fast as 3ds Max, the proxies worked pretty well when scattering a forest with millions of polygons:
Our second test focused on testing the strength of the tool, so we applied it to a scene with unusually high polygon counts.
Proxies vray rhino generator#
We put together a Canstruction generator (for a possible future installation) and tested the proxy scatter at varying densities: The first test with the tool was a scatter of the classic Campbell’s soup can. The scattering process (executed with Rhinoscript) is slower than Forest Pack but by keeping the tool within the grasshopper interface, we are able to control proxy parameters while applying them to complex surfaces.
Like Forest Pack, our Python script offers proxy translation, scaling (1D/2D/3D), rotation, and jitter. The component we’ve put together is similar to Forest Pack, a powerful 3ds Max plugin by iToo software. This results in a significantly improved user experience as well as increased speed and complexity of renderings. It’s linked to this mesh geometry, which is imported only at render time. In short, a proxy is a crude representation of a complex mesh geometry within modeling space. We’ve enjoyed taking a look at the new version of VRay for Rhino and are especially excited about the addition of VRay proxies.
