[Rhino]Rhino Displacement tools - Polyloop

jbshorty · 28th June 2007, 02:02

Hi people. Rhino 4 now has a free plug-in tool for using displacement mapping on NURBS surfaces. It works in both real-time and render-time. and because it's NURBS based, it displaces only the render mesh. This makes the render mesh topologically independent (very different from SDS modeling). So the mesh topology will organize itself according to greyscale levels of the map. In addition to viewing displacement in real-time, there is also a function which can extract the displacement mesh into a real mesh object. So the displaced object can be used for manufacturing. I have been waiting for McNeel to unleash this function from the Brazil render engine, so this news makes me very happy. Read about it in the Rhino Labs section:

WOW thats what I call a high poly model

that's OK. It's intended for manufacturing, not really for animation. So this is a preferred type of triangulated mesh. The mesh is adjustable so it can be more or less dense at any time you choose... For me it is exciting because it will now be easy to produce a very high-quality textured surface with high density only where it needs to be. this is unlike Rhino's old method of creating rectangular mesh grids based on greyscale maps. In that case, much detail was lost and much density was wasted. I asked for this feature over one year ago, and i'm happy to have it available now...

Here are a few other "old" image examples posted a while ago by David of McNeel. This is a better example of using dense mesh only where necessary...

This tool may make making emboss easy.

I hope in the future that will be true, as I often need to emboss our client's logo on the item for moulding. But i think it will need better adaptive subdivision before that can be practical...
