Monochrome Display Mode Performance

Rhino
1

For us architects the Monochrome display mode is very good for conceptual design as it black and white and edges are clearly defined. Like pen drawings.

But there are severe performance issues compared to for example “Shaded Mode”.

Would be possible to somehow improve the performance so that these modes become usable also for more complex models?

I’ve made a bit of a study and what actually makes the Monochrome mode are the two settings “Show Edges” & “Show Silhouettes”. Unchecking those increases the performance to approx the same speed as the other modes. But unchecking them also makes them quite unusable.

Would it be possible to somehow improve the speed of the creation of the linework?

It would be fantastic.

Thanks

Hej Erik -

The Monochrome display mode is a “technical” display mode, just like Technical, Artistic, and Pen. These display mode rely on a different set of display meshes and having two sets of display meshes for all objects will naturally have an impact in huge models or with less capable GPUs.

Have you tried modifying the Arctic display mode to also render edges? Perhaps that will get you close.

Apart from that, if you can upload a 3dm file that is slow on your system, we can have something to test optimizations on. Your SystemInfo data would then be good to have as well.

Hello,

I uploaded the file.

I have a lot of custom display modes here - so I experimented a lot.

It’s just that for designing things in an environment that is as clean as possible, one needs white paper, with black lines … nothing else.

Thanks

Hej -

Thanks, I’ll take a look and put it on the list.
→ RH-78712 Display: Monochrome - room for speed optimizations?

FWIW, …

I definitely wouldn’t call Monochrome white with black lines and nothing else…

One of these is (a modified) Arctic, the other is Monochrome.

Wim,

sorry it was an understatement.

Black lines, white background. Surfaces and a bit of shadow. That’s all fine.

No worries, Erik.
You model is available to the developers to see if there is room for optimizations in this area. I don’t know when they will have a chance to take a much closer look.
