SubD/Crystallon/Dendro/PBR fun in the Rhino 7 WIP

I started with SubDThickenCurves and then used that SubD surface in GH with Crystallon to create a variable lattice structure, then to Dendro also in GH to bake out the mesh. I finally used the new Physically Based material with a subsurface setting and Rhino Render in v7 for the image.


Very cool, Brian!

Hello Brian,

Could you advise me on how to get a cheap and cheerful similar effect in Rhino 5 with a very low-power laptop ? We regularly build 3D printed models for our wind tunnel with polyamide powder sintering and it would be cool to be able to preview the model in Rhino. They look a bit like this when they are done (image from Polyrepro, looks like the Louvre Abu Dhabi to me):

Hi Graham,

If you are using Rhino Render in Rhino 5, the best suggestion I’d have would be to use a few Rectangular lights around the model, one cool in color, one warm and one from behind. You won’t have the physically based material that I was experimenting with here in the Rhino 7 WIP which has a sub-surface scattering ability so that will limit the translucency effect in the thin areas but it should get you close.

Thanks Brian… Here using the white mat plastic material, a blueish white light, an orangeish one and a white one overhead, plus a dark grey ground plane for a simple tower model… I don’t think I’ll give up the day job :smiley:

The two things that will make this hard to copy using Rhino 5 Rhino Render will be the lack of indirect illumination of light bouncing around between surfaces and also the SSS (sub surface scattering) of light through thin areas. Rhino 7 Rhino Render can do both which makes for more realism with 3D printing materials. Your light color, balance and placement look good though.

Sir could you explain the process for rhino 6 then

In Rhino 6 Rhino Render, I’d use the Raytraced display mode to get indirect illumination. Then use ViewCaptureToFile to save the render. This will get you closer than Rhino 5 could. If you own Rhino 6, you can use the Rhino 7 WIP now too. See the Serengeti category or the Download page on Rhino3D.
