Display differences between Windows and Apple computers

[michael.donn]

In July 2024 on the LadyBug Tools discourse Visualization Set preview on Apple Computers - #18 by MichaelDonn - ladybug-tools - Ladybug Tools | Forum I reported a difference between the display of legend in windows between Windows and Apple computers. Back then, I created a workaround that avoided students in my 300+ person class not seeing a difference between the two operating systems.

Almost 12 months later, the problem still exists.

On a Windows machine I get this:

On an Apple machine, the display looks like this:

The developers of LBT suggest the error (?) for the Apple OS is here:
" the specific part of RhinoCommon that is failing to render the legend correctly in this case is the DisplayPipeline.DrawSprite method. You can see that it is called here inside the component source code to render the legend to the screen:"

This is correct; Rhino on Mac does not have a proper implementation of DrawSprite. I’m sure we will have something working in the future, but it is hard to say when that will be.

Kia ora @stevebaer

Thanks for the rapid response. I am distributing a LadyBug Tools environmental science learning platform to a class of 300+ first year students in July. I noted this issue last year in July.

I assume that I need to tell the Windows students their graphics will look better than those who use Apple computers? And re-label some of the interaction sliders/components so they specifically address these differences?

[stevebaer]

That seems correct for now.

…the display of legend… the DisplayPipeline.DrawSprite method…

FWIW, one shouldn’t have to draw sprites to draw a screen legend like the one in your screenshot. See e.g.:

Draw To Screen Space Foreground From DrawViewportWires

Hi All, I’m experimenting with implementing DrawViewportWires in GHPython for drawing e.g. legends on top of 3D geometry generated in Grasshopper. Here’s a quick example: [2020-11-25 11_37_02-Window] The issue I’m trying to resolve is that the rectangles (drawn with Draw2dRectangle ) are drawn behind the 3D geometry that is drawn by Grasshopper (though it still appears to obscure the wires of the 3D mesh), while the text is drawn in the foreground: [2020-11-25 11_37_32-Window] Here’s a mi…

GHPython Content From AECtech+ Barcelona Workshop

Hi All, I ran a short GHPython workshop at the AECtech+ event in Barcelona. I used this GitHub repository for sharing files with the workshop participants, and thought I’d share all the content here as well. Here is the workshop and content descriptions/links from the GitHub readme file: Dynamically Drawing and Reacting to Things with GHPython There is more to running GHPython components in SDK Mode than compiling plugins. We will demonstrate, explore, and combine these overlooked features th…

I’m not entirely sure what all their code does, but one might try to comment out the draw sprites bits and see if the legend still draws.
