Hi, i am trying to get relationship between two closed curves. As you can see in drawing, one curve contains the other, but "PlanarClosedCurveRelationship " returns mutualIntersection. Am I missing something? Thanks for help.

                    RegionContainment containment = RegionContainment.AInsideB;
                Curve newCurve = obj.Geometry as Curve;

                Plane plane = new Plane();

Clipping plane in display conduit, visualization problem (C++)

@Pablo_Garcia-Amorena wrote:

Hi,

In a display conduit I need to draw a mesh being clipped by a plane (that is also drawn).

It’s important to highlight the intersection between the mesh and the clipping plane, like Rhino command ClippingPlane does. Though, I don’t manage to get this.

Here’s an example of input mesh and clipping plane:

objectToClip
objectToClip1633×1002 55.9 KB

My conduit properly clips the mesh but fails to draw the intersection mesh-clipping plane:

conduitVObject01
conduitVObject012150×1157 151 KB

conduitVObject02
conduitVObject022052×1244 54.3 KB

Rhino command ClippingPlane properly emphasizes the intersection curve: how can I get that through the conduit?
Here I attach the sample command I made to have the results above (it also contains the input mesh and plane):

cmdClippingPlaneConduit.cpp (6.1 KB)

Thanks,
Pablo

Hi everyone,

I was working a plugin project on the Windows system, and when I try to clone and open repository in Visual Studio on my Mac system. Expected outcome happened, .dll directories changed.

When I try to browse and add .dll files, I couldn’t find .dlls in the Rhino6 package as well as Windows version.

Is it possible to write a non destructive mesh modifier plugin?

@adel.albloushi wrote:

Hello,
As the title suggests, i want to look into the possibility of developing a non-destructive mesh modifier system that takes as an input a mesh, has a few options and parameters, and allows for the initial mesh to be modified arbitrarily by the user (since it’s a non-destructive modifier).
Most mainstream 3d packages have that - 3ds, c4d and blender come to mind.

Now i want this to be a hobby project, also a good excuse to better myself in c++.

The question i want to ask is simple enough. In principle, is it possible?

How to access a local variable (Brep or Brep) outside of a for loop in c#?

Thanks in advance for your help.

            doc.Objects.AddCurve(DuplicateEdgeCurve2);

}

DuplicateEdgeCurve1 (not visible outside the loop).

fit_curve_fail.3dm (32.5 KB)
When I run the code below on the curve in the document attached, the resulting curve has 1 control point on the origin, resulting in a very bad curve shape locally.

var res = RhinoGet.GetOneObject("Curve to fit", false, ObjectType.Curve, out var cRef);
if (res != Result.Success)
  return res;

Curve toFit = cRef.Curve();
double fitTolerance = 1e-8;
var smoothed = toFit.Fit(3, fitTolerance, 0.0);

Registering plugin problem

@cp1 wrote:

Dear all,

I am trying to automatically register a Rhino plug-in under Windows 10 via a registry entry like described here.

On first startup of Rhino6 after installing the plug-in, I get the following error: 'Unable to load …rhp plug-in: no class derived from CRhinoPlugIn in plug-in file. After hitting ‘OK’ Rhino starts normally and the plug-in works correctly. Checking Tools/Options/Plug-ins shows that the plug-in was loaded three times.
When I close and open Rhino again no error message shows up and everything works.

The problem seems to be connected with the automatic loading procedure: When I load the plug-in via drag and drop it works with no error message showing up.

The plug-in was compiled using MSVC 2019 Version 16.4.1, the Rhino version is RH6 SR22 (6.22.20028.13281), the SDK version is 6.22.20028.13281.

Has anyone an idea what might cause the error message?

Best,
Clemens

Default Print Colour to By Display, All Objects

@Jonathan_Hutchinson1 wrote:

Output Colour, at the printing stage, By Display is obviously really handy.

What I often need is Print Widths + Display Colours at the same time - this is what changing all the Print:: By Display helps with.

Is there a way to script it? In rhinoscriptsyntax I don’t see a By Display option :frowning: https://developer.rhino3d.com/api/RhinoScriptSyntax/#object-ObjectPrintColorSource Maybe it’s possibe in Rhinocommon?

But I guess for all new objects the default will still be ByLayer printing?

Controlling ByDisplay , by layer, would be cool maybe?

Using Brep.CreateBoolean.... operations

Hello everyone,

i got issues using the boolean operations of the Brep class.
Even though I know that two breps do intersect the CreateBooleanSplit method returns an empty array. If I understand correctly this means that the split was successfull, but why do I get no results then?

This is the code i wrote: (all Breps are solid and manifold in this example)

//Extrude shape along line.
Plane linePlane = new Plane(line.From, Vector3d.CrossProduct(line.Direction, plane.ZAxis), plane.ZAxis);
Curve orientedShape = shape.DuplicateCurve();
orientedShape.Transform(Transform.PlaneToPlane(Plane.WorldXY, linePlane));

Brep brep = Brep.CreateFromSweep(line.ToNurbsCurve(), orientedShape, true, tolerance)[0];
brep.Faces.SplitKinkyFaces(); //fix 4-sided surface for boolean.
brep = brep.CapPlanarHoles(tolerance); //sweep doesn't do it!

//Move brep for boolean opperations.
brep.Transform(Transform.Translation(intersectionVector));
brep = brep.DuplicateBrep(); //fix brep transform for boolean.
                
for (int i = 0; i < placedBreps.Count; i++)
{
    Curve[] intersectionCurves;
    Point3d[] intersectionPoints;
    if(Intersection.BrepBrep(brep, placedBreps[i], tolerance, out intersectionCurves, out intersectionPoints))
    {
         Brep[] splitResults = Brep.CreateBooleanSplit(brep, placedBreps[i], tolerance);
         brep = splitResults[0];
         placedBreps[i] = splitResults[1];
    }
}

Hopefully someone knows how to use these methods!
Best regards,
Frezap

When I set texture projection mode for my texture:

And this one results in the correct mappingChannel mode
SetProjectionMode(TextureProjectionMode.View, ChangeContexts.Ignore);

Am I doing something wrong? (Or the enums are maybe mixed?)
