How to adjust line thickness

I'm not sure "TubeVisual3D" wouldn't be a better choice for the arch itself, but I am unfamiliar with how to persuade the end points, angles, and so on.

For the moment, I have managed to cobble together some PipeVisual3D segments, but then there's an issue I'd like to smooth the edges of the arch group., which again, a single TubeVisual3D object might be a better fit.

var archPoints = CalculateArcPoints(new Point(),
crossBarArchRadius, 16, 90d).ToArray();

var archThreeDeePoints = archPoints
.Select(p => new Point(p.X, p.Y + paddingHeight)).ToArray()
.Select(toThreeDeeTransform.Transform).ToArray();

var archGroup = new ModelVisual3D();

foreach (var archPipe in archThreeDeePoints
.Take(archThreeDeePoints.Length - 1)
.Zip(archThreeDeePoints.Skip(1),
(a, b) => new PipeVisual3D
{
Fill = postFill,
Point1 = a,
Point2 = b,
Diameter = crossBarDiameter
}).ToArray())
{
archGroup.Children.Add(archPipe);
}

You can see what's going on here. It's easy enough to add more segments, 32, 64, 128, etc, but that's more objects to render. If I can do the same thing with a single TubeVisual3D, that's what I want.

And now with a persuaded TubeVisual3D.



var tube = new TubeVisual3D
{
Fill = postFill,
Diameter = crossBarDiameter,
Path = new Point3DCollection(archThreeDeePoints),
IsPathClosed = false,
};

Very spiff indeed!

I think I see what's going on re: orientation, and it makes sense when you pause not to over-think it.

X is depth, front/back, Y is lateral, left/right, and Z is, of course, height, up/down.

In these attempts, I have my X and Y reversed, at least if you consider the kicking plane of the goal post to be front.

This is cool! You should write a blog about this. Are you going to publish it as open source? It could be included as an example in this project!

These are compelling thoughts. I will give it some consideration.
