Text Tag and Clipping Plane

Grasshopper
1

Hello,

For some reason the text tag component is not displaying in the rhino viewport when I have a clipping plane activated.
Any ideas?

Many thanks,
Miriam

@steve do you know?

2D or 3D text tags? Is the position of the tag clipped by one of your planes?

I tested that with 2D tag and they were completely on the ā€˜insideā€™ of the clipping plane - i.e. they should have been visible. I tried both with the .9 version in RH5 and the 1 version in RH6 and got the same result - the tag is invisible.

Yes, I made sure the position of the tag was at the correct side.
Problem only with the 2D Tag. 3D Tag works fine, however doesnā€™t have a parallel view option.
Maybe to expose the view parallelism as an option and keep as only one component? Just an idea.
Thanks!

@stevebaer, the method I use to draw 2D text tags is DisplayPipeline.Draw2dText(string, Color, Point3d, bool, int)

Iā€™ve put a YT item here: https://mcneel.myjetbrains.com/youtrack/issue/RH-37028

@piac you are mentioning the wrong Steve. :blush:

Thanks David; I moved this to 6.x since it doesnā€™t seem to be on the critical path for V6, but I could be confused

I donā€™t think itā€™s critical, unless itā€™s symptomatic of some deep issue causing all sorts of other problems too.

11

Thinking about it a bit more, I guess I just need to disable clipping planes when drawing 2d text. This is pretty simple; Iā€™ll move it back to 6.0

12

Well. . .
Are you saying that you will show all 2d text no matter which side of the CP it is falling?

13

I believe so; Iā€™ll need to investigate a little deeper. Many of the 2d text functions are set up for drawing text on the ā€œscreenā€ and not in world space. In that specific case, clipping planes should not be considered.

14

Hmm. That would probably not be so nice.

RH-37028 is fixed in the latest Service Release

Hi,

  1. I was wondering if there is any way to control clipping box?

  1. I tried with C# node but got error I think I am missing sth

Error (CS0120): An object reference is required for the non-static field,
method, or property ā€˜Rhino.Display.DisplayPipeline.Draw2dText
(string, System.Drawing.Color, Rhino.Geometry.Point3d, bool, int)ā€™(line 59)

  private void RunScript(System.Drawing.Color x, object y, ref object A)
  {

    Rhino.Display.DisplayPipeline a = null;
    a.Draw2dText("blllaaa", x, new Rhino.Geometry.Point3d(0, 0, 0), true, 1);

    A = a;

  }
  1. also, I could not find a solution to control Text size according to this method, did you remove Text Tag settings from AppData?

Thanks @michaldengusiak - thatā€™s a bug. Rhino should be managing the object bounding box for all objects that it draws - you shouldnā€™t need to do it at all.

@brian thaks for reply, regarding my second question should I log as a separate question?
