Displacement uses the objects render mesh as the starting point and then applies the quality setting over that to divide the polygons. Try Explode on the object and then Join. This will make it a polysurface not an extrusion. Then adjust it's custom render mesh in the Properties panel.

The only option I can think of would be to have different mesh resolutions made with ReduceMesh and hide and show them as needed for the different views. I know it's not ideal but it could work to reduce the poly count rendered.

Not only that, but i can actually visualize the displacement preview in my viewport which really helps in many situations. I often extract the displaced render mesh from rhino objects to use in other softwares or to have it always baked in my model so i don’t have to wait for rhino to recalulate the displacement when changing views etc. So here is my question: is there a way to generate a render mesh in rhino that is view dependent (like i’ve seen done in Blender) and then render the displaced object in vray?

This will control the height of the two tonal extremes based on the source image. You can also edit your image to adjust the height in areas by dodging and burning the image externally. Save over the image in another program and Rhino will auto update the change in the displacement.

You can send it to tech@mcneel.com <br /><br />The texture used, geometry transitions at seams and the displacement settings are all factors in what the polygonal structure of the displacement will be. You can also use MeshRepair to fix small gaps after extracting the displacement mesh or edit it externally in programs specific to mesh/scan processing.

There are some cool features available with render meshes, but everything I use Rhino for must be NURBS objects that can then be passed on to SolidWorks. I'd love to see you do another of your great videos exploring the process of how some of these render mesh functions could be used and then a NURBS surface or object created from it.mcramblethttps://www.blogger.com/profile/11994079634015944240noreply@blogger.comtag:blogger.com,1999:blog-4737331313003219794.post-90999083336668963832013-05-28T06:03:34.153-07:002013-05-28T06:03:34.153-07:00Hi,

The Zbuffer technique isn't reliable and doesn't automatically crop to the relief outline.
