| Rhino Displacement tools
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: http://en.wiki.mcneel.com/default.as...placement.html shorty  |

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... http://news2.mcneel.com/scripts/dnew...m=245847&utag= http://news2.mcneel.com/scripts/dnew...m=245845&utag= shorty Last edited by jbshorty; 28th June 2007 at 13:43. |

That's to your collection, shorty http://www.sitexgraphics.com/html/ra...ototyping.html http://www.sitexgraphics.com/html/rhino.html not too expensive for RM-compatible renderer.

I have demo'd the AIR engine, and it's quite nice! Displacement, interactive preview (not quite FPrime or modo), blobby point clouds, Darktree Simbiont texture support, etc. Also you can assign shaders independently from Rhino's RDK material editor so multiple engines can be used side by side. But I'm still hoping to see this functionality built directly into Rhino as it can greatly expand it's reach for manufacturing purposes. I think McNeel will probably put more focus on this once Brazil is a shipping product (the same staff of McNeel who are porting Brazil to Rhino are also the authors of the displacement plugin)... jonah |

hehe. I don't believe in hope, only believe in facts...
