how to change rendered objects settings in rhino

To do that in Rhino requires some understanding of how the meshing system works. The idea is to use the least number of mesh faces you need to have adequate resolution for your job – and no more. The data set can become huge, and considering that this data also needs to be dynamic (you want to rotate your shaded model and look at it, right?) the ability of your computer to process this data in realtime quickly reaches its limit. Meshes are a bit like pixels in an image – the more pixels (mesh faces) you have, the finer the image (model) resolution is, but more data is needed to describe the image (model). OK then, why don't I just mesh everything very finely and with high resolution? Won't that solve my problem and let me forget about it?Īctually not – it will probably make things worse. Hence this long and windy page full of info and advice. If you want the best meshing in Rhino, you need to understand how these settings work and how to manipulate them. That's a good question - and subject to much debate. Why do we need mesh settings anyway? Isn't Rhino intelligent enough to figure all this stuff out without my having to tell it what to do? Although all the meshes are created with the same engine, there are a couple of important differences between them. They do not affect one another and each can have its own settings.

The functions that create real, editable meshes like Mesh and Export (.stl) are important in many applications, as other downstream programs or processes often need polygon mesh objects to work with.Īll the types of mesh objects can exist simultaneously in one file. Although you can't edit these in the original Rhino file, you can control how they are created with the same group of mesh density settings. stl) will also create mesh objects (in the exported file).

The same meshing engine in Rhino is used in both the creation of analysis meshes for the functions like Draft Analysis and Curvature Analysis, EMap and by the Mesh command ( Tools > Polygon Mesh > From NURBS Object), which creates a real mesh object directly from a NURBS object.Įxporting from Rhino with certain polygon-based formats (such as. The render mesh is always an approximation of the surface, so there are almost always gaps between the faceted render mesh and the actual smooth surface. While a mesh has the advantages of shading speed and adjustability, there is a disadvantage. So what you see on the screen when the model is shaded is a special, invisible polygon mesh (the render mesh) that is attached to the actual NURBS surface. Although Rhino is a NURBS surface modeler, it uses polygon meshes created from those surfaces for visualization purposes.
