Class for injecting control directly into viewport?

Is there an exposed class for adding buttons, sliders etc directly into a viewport?

I can do it externally with a win32control wrapper, but transferring info is messy and exiting is messy as well.

Registering plugin problem

I am registering our net.commons plugin programmatically, by making the usual registry entries at:

HKEY_LOCAL_MACHINE\Software\McNeel\Rhinoceros\6.0\Plug-ins<your_plugin_guid>`

This works OK, except that the plugin isn’t enabled… this means that on every Rhino 6 start the user is asked if they want to load this plugin.

Is there a setting that I can add to avoid this?

Adding options for my plugin in option panel

Hi,
I’m trying to add options for my plugin in Rhino option panel. I believe I must create a class inheriting OptionsDialogPage, but I get an error message concerning the constructor, and I can’t figure out how to do this. Any Idea?

 Public Class MSWOptionPanel
    Inherits Rhino.UI.OptionsDialogPage

    Public Overrides ReadOnly Property PageControl As System.Windows.Forms.Control
        Get
            Return New MSW_OptionControl
        End Get
    End Property

End Class

Best regards

I am implementing a method that computes geodesic distances (from a source point or curve) on a brep using a background mesh. How can I visualize a combination of a gradient and a set of contours? Can I combine a gradient and a stripe map?

Does anyone have an example of either one or both combined?

Hi All
Is it possible to create (display) Rhino objects (lets say curves) which are not movable and they are not locked, so I can select them (but not move or other transformation) and delete them. Is it possible with C++?

Hello,

The method DisplayPipeline.DrawSprite(DisplayBitmap bitnap, Point3d worldLocation, float size, bool sizeInWorldSpace) is not using the Point3d in world coords, it seems to be using th x,y screen coordinates.

Here the code:

 public class DrawSpriteCommand : Command
{
    private readonly DisplayBitmap _bm;
    private bool _enabled;

    public DrawSpriteCommand()
    {
        Instance = this;
        _bm = new DisplayBitmap(new System.Drawing.Bitmap(@"C:\Users\MyUser\Desktop\image.jpg"));
    }

    public static DrawSpriteCommand Instance { get; private set; }

    public override string EnglishName => "DrawSpriteCommand";

    protected override Result RunCommand(RhinoDoc doc, RunMode mode)
    {
        _enabled = !_enabled;
        if (_enabled) DisplayPipeline.DrawOverlay += DisplayPipeline_DrawOverlay;
        else DisplayPipeline.DrawOverlay -= DisplayPipeline_DrawOverlay;
        doc.Views.Redraw();
        return Result.Success;
    }

    private void DisplayPipeline_DrawOverlay(object sender, DrawEventArgs e)
    {
        e.Display.DrawSprite(_bm, Point3d.Origin, 15f,false);
    }
}

Here a video of the behavior:

.NetCore (1.0 1.1 2.0)
. NetStandard (which one 1.0 1.1 … 2.0)
I found and I used template for Rhino and Grasshopper. Is there an example for a DLL ?

I tried .NetStandard/.NetCore with no compilation error and I get an error message in Grasshopper. What I miss ?

An example I used (Thanks for the new function in RhinoCommon)
using Rhino.Geometry;

namespace TestClassLibrary1

    public static class Class1
    {
        public static Mesh Catmull(Mesh mesh, int level, int creasedEdge)

            Rhino.Geometry.MeshRefinements.RefinementSettings rr = new Rhino.Geometry.MeshRefinements.RefinementSettings();

            rr.Level = level;

            Rhino.PrivateMeshCommands.MeshTypes.CreaseEdges ce = Rhino.PrivateMeshCommands.MeshTypes.CreaseEdges.Auto;

            switch (creasedEdge)
            {
                case 0:
                    ce = Rhino.PrivateMeshCommands.MeshTypes.CreaseEdges.NakedFixed; break;
                case 1:
                    ce = Rhino.PrivateMeshCommands.MeshTypes.CreaseEdges.NakedSmooth; break;

Python - watch cursor and place object

@onrender wrote:

Hi,

I have a question for the following procedure. I am also not sure if it is possible in python.

  1. Watch position of cursor,
  2. Watch angle of the line that the cursor covers,
  3. Move object to cursor (how the cursor moves around the object can follow the cursor) (Dynamic draw?)
  4. Align object to line (and Dynamic draw?)
  5. Place object by a click.

I know that Event watcher exists for C# but all together is even more foggy.

C# vs Python

Hi,

I have found a video online https://vimeo.com/247048808 and they are talking about the calculation time of each language (C#, VB, Python). Python seems very slow. I believed, the calculation time between C# and Python is negligible. The test shows the difference.

However in terms of development, Python is still more comfortable and no need to be compiled. It works like a real time script. I think the best way for script creation is IronPython because when calculation time become crucial it is easier to turn IronPython into C# code.

Suppose something trivial is compromising the final result. Any hint will be greatly appreciated.

“‘Rhino5x64_d.exe’: Loaded ‘C:\Program Files (x86)\Rhino 5.0 x64 SDK\Bin\x64\Rhino5x64_d.exe’, Cannot find or open the PDB file”

… and many others

It seems that PDB files are missing in my Rhino installation. Has anyone had this problem before?

Thanks
