Draw3dText issue in Rhino 7 Beta

michaldengusiak · November 6, 2020, 8:58am

I am using Rino.Inside.Revit 7.0.20309.6003, 11/04/2020

I am not sure why my
args.Display.Draw3dText(text3d, System.Drawing.Color.Black);
text3d does not work for Rhino 7?

Rhino 6
Rhino6_draw3dText

Rhino 7

HoareLea/SAM/blob/173c3e63fc5146ebda8de6fcf09024e485de2c22/Grasshopper/SAM.Analytical.Grasshopper/Component/SAMAnalyticalLabelPanel.cs#L217


            List<Text3d> text3ds = GetText3ds();
            if (text3ds != null)
            {
                Point3d cameraLocation = RhinoDoc.ActiveDoc.Views.ActiveView.ActiveViewport.CameraLocation;
                foreach (Text3d text3d in text3ds)
                {
                    if (text3d == null)
                        continue;
                    Point3d point = text3d.TextPlane.Origin;
                    if (point.DistanceTo(cameraLocation) > 16) continue;
                    args.Display.Draw3dText(text3d, System.Drawing.Color.Black);
                }
            }

            base.DrawViewportMeshes(args);
        }

        #endregion IGH_PreviewObject
    }
}

@kike - is this something you can help with?

michaldengusiak · November 19, 2020, 8:20am

@kike let me know if you need any explanation I am happy to assist to get it solved

Hi @michaldengusiak,

Sorry for the late reply.

Please test this Grasshopper document and tell me if it works for you.
Are you overriding Component.ClippingBox?

Draw3dText.gh (10.3 KB)

michaldengusiak · February 18, 2021, 7:43pm

yes your script works fine,

yes, we have ClippingBox included in line 98 of the same code… can you spot any issue there…?

we have clipping box

              if (!panel.TryGetValue(name, out text, true))
                  text = "???";
          
          
    double value = double.NaN;
              if (double.TryParse(text, out value))
                  text = value.Round(Rhino.RhinoDoc.ActiveDoc.ModelAbsoluteTolerance).ToString();
          
          
    dataAccess.SetData(0, text);
          }
          
          
public override Rhino.Geometry.BoundingBox ClippingBox
          {
              get
              {
                  Rhino.Geometry.BoundingBox boundingBox = base.ClippingBox;
          
          
        List<Text3d> text3ds = GetText3ds();
                  if (text3ds != null && text3ds.Count != 0)
                  {
                      foreach (Text3d text3d in text3ds)
                      {

You are calling Draw3dText from GH_Component.DrawViewportMeshes I would try doing it from GH_Component.DrawViewportWires.

michaldengusiak · February 25, 2021, 3:57pm

OK we tested two method and it still does not work…
I mean it works on Rhino 6 but it does not on Rhino 7…

            if (point.DistanceTo(cameraLocation) > 16) 
                continue;

            args.Display.Draw3dText(text3d, System.Drawing.Color.Black);
        }
    }

    base.DrawViewportMeshes(args);
}

public override void DrawViewportWires(IGH_PreviewArgs args)
{
    List<Text3d> text3ds = GetText3ds();
    if (text3ds != null)
    {
        Point3d cameraLocation = RhinoDoc.ActiveDoc.Views.ActiveView.ActiveViewport.CameraLocation;
        foreach (Text3d text3d in text3ds)
        {
            if (text3d == null)
                continue;

any idea what could be wrong …we still unable to get it to work

kike · March 12, 2021, 11:21am

What happens if you draw the texts a bit offseted from the planes?
I’m wondering if is a z-fighting problem.

michaldengusiak · March 15, 2021, 8:43am

we implemented, move along normal vector and still the same issue

we tested again on Rhino 6 and is working perfectly and Rhino 7 is not.
We also added baking and works fine in Rhino 6 and in Rhino 7 give some very thing sth that we can not zoom into or select…it disappears when zoon in or out

We strongly belive is Rhino 7 issue as it works perfectly on Rhino 6.

michaldengusiak · April 21, 2021, 11:19am

as we tested today…this must be Rhino 7 issue here is video with 1 element in Rhino 6 and Rhino 7
