Wish Grasshopper windows with gradient transparent background

Hi David, All,

You know the drill when working with a laptop/single monitor: a constant dance of window arranging, or double-clicking GH window bar, or alt+Tab to switch between GH/Rhino windows.

simple example of problem, trying to work on these two windows at once:

proposed solution, Grasshopper window has a gradient slider in the canvas area to let you see through it:

you can move the two sliders that define when the full opacity of the GH canvas background starts/stops

The gradient’s length can be minimized to a very quick transition, just enough to make it clear that there is some masking going on:


Lots of good ideas there. Also I agree with David that true transparency is just terrible. I know Dynamo does it, but I can’t imagine working that way. Maybe it’s cool for documenting/taking screenshots once you arrange things neatly for a picture taking day, not as a working mode.

This is what the example I posted above looks like with true transparency:

This is the kind of amateur UX work that gives me nightmares.

You should try Wormhole. It works very well, and it does pretty much what you want.

That’s neat, but no it doesn’t solve any of the UX challenges I’m struggling with. It’s still some form of discrete rectangular window-arrangements, which is what I’m trying to avoid completely.

I posted that two comments up :smiley:

It is easy to make the entire GH window transparent via windows forms in C# however, it gives everything part of the GH window an opacity, not just the canvas. I believe I saw this from David Rutten some time ago. Will drop this here for the sake of the discussion, even though it is not ideal.

Oh, sorry I didn’t check the thread through.
But yes, Wormhole is ‘sort of’ a solution. I find it very useful and use it all the time.

I understand it’s not ideal, but it’s closest to a transparent work-surface.
Transparent background [or dedicated viewport window for Gh] is a thing that people are asking as far as I can remember.

Your “concept” seems interesting. Maybe you should build it :grin:

I use TopMostViewPort and it works quite well for me. Still rectangular window management but once setup I don’t really change much and can adjust the viewport size by simply dragging the top right corner. Of course you could have Grasshopper full size but I like seeing the command line, layers/properties panel, osnaps, etc.


I’m just ‘the idea guy’ :joy::joy::joy:
I don’t know how to code. Only clicking and dragging all day.

That does look very good. I’ll definitely use that for now. Thanks Louis!

Gustavo- This is a problem that many node based editors face. Blender’s compositor solves the issues you talk about in a relatively flexible way- you can either work in a separate window or overlay

It can be a very interactive way of working the nodes. There shouldn’t be a reason you can do a gradient fading overlay of the window- although that would be a new UI paradigm - but that said it doesnt seem that we have figured out the best way to integrate nodes into Rhino proper.
