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:
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:
Here’s a minimal example and file of this behaviour:
201125_DrawRectangle2d_00.gh (4.9 KB)
I can see that this issue has been brought up previously by @andheum. But I’ve not been able to find any examples/code that demonstrate how one has resolved this (notably how to “add a callback to the DisplayPipeline.DrawForeground event”). I should also mention that I’ve been given great pointers by @dave_stasiuk and @tom_svilans on how they draw to the foreground from a display conduit in a compiled component. But before going down that path, I just wanted to make sure that I’m not missing something here.
So, is it possible to always draw to the screen space foreground from DrawViewportWires
?
Best,
Anders
