Isometry in Cycles (Cyclometry?)

Ah, bummer, I thought the thicker “silhouette” edges were something that the display mode figured out… --Mitch


The display mode is called Raytraced.

Nope… good ol’ fashioned human labour.

Incidentally here’s a screen-cap of the viewport:

What kind of rendering device do you use?

CPU, I get corrupted display (and sometimes crashes) when I try my AMD.

Device 0: CPU > Intel Core i7-6700K CPU @ 4.00GHz > 0 | False | True | False | CPU
Device 1: OPENCL_AMD Accelerated Parallel Processing_Tonga_01:00.0 > Tonga > 0 | True | True | True | OpenCL

You could try setting environment variable, see

for info.

your rendered view looks nice - would you share the setting? maybe even add this as another option to rhino wip?

That seems to work, adding the environment variable adds a third ‘device’ to my list, which if I select it is a one-way ticket to hard-crash central, but selecting the ‘old’ AMD device now works. It’s a little bit faster than CPU, not hugely. Is that expected?

I have to say it’s rather nice not having the ventilator kick in right away while using the card.

It’s standard settings, using one of the standard HDR environment maps.

ok, sorry, don’t get it. do i have to add the HDR somewhere in settings -> view -> display modes -> rendered? or somewhere else?

That’s a labour of love. Looks amazing… I’d have that as a poster or a screen saver, but then I’m old(er) and it brings back memories :smiley:

Render settings panel (the tabs where one can have layer manager, material manager etc), enable Skylighting and either set a custom environment, or let it use the same environment as the background.

got it, thanks. but there seems to be more going on, i mean the thick edges. is it made via a custom material?

The thick edges are done with pipe and a solid black material…

When does the crash happen?

got a similar look now. the gird is a small and simple texture as color on a custom material which i used as ground plane. but it’s also not displayed infinite, also AMD card :unamused:

thanks for the quote - should have read more carefully before posting, sorry.
can also be done in the display settings. Surface Edge Settings -> Edge thicknes (pixels)

Thanks David for the explanation. I wanted to know if that silhouette effect was automatically created by the renderer, but seems like It is not.

A few seconds after I switch to Raytraced using the new device.

Ah, the Intel OpenCL stuff seems to be quite buggy. I thought you were using your AMD device instead. OpenCL on CPU is probably not noteworthy faster than vanilla CPU.

edit: I probably should filter intel OpenCL devices out of the list until those become stable.

If you mean that you see the groundplane edges when you zoom out a lot - yes, that is because Cycles has only float precision. On larger coordinates you’ll see render errors. That is why (at least for now) the groundplane has a finite size.

edit: nvm, I just see the problem you actually meant. Could you post the 3dm for me so I can have a look? Also info on your GPU could be useful (output of RhinoCycles_ListDevices and what you selected from that list)
