Class ModelArrows

A collection of arrows which are visible in 3D.

Examples
// Create some arrow locations.
var vectors = new List<(Vector3 location, Vector3 direction, double magnitude, Color? color)>();

var target = new Vector3(15, 20);
var squareSize = 25.0;
var maxDistance = Math.Sqrt(Math.Pow(squareSize, 2) + Math.Pow(squareSize, 2));
for (var x = 0.0; x < squareSize; x += 1.0)
{
    for (var y = 0.0; y < squareSize; y += 1.0)
    {
        var l = new Vector3(x, y);
        var d = (target - l).Unitized();
        var distance = target.DistanceTo(l);
        var r = distance / maxDistance;
        var c = new Color(x / squareSize, y / squareSize, 0.0, 1.0);
        vectors.Add((l, d, r, c));
    }
}

// Create a model arrows object.
var modelArrows = new ModelArrows(vectors, false, true);

Constructors

ModelArrows(IList<(Vector3 location, Vector3 direction, Double magnitude, Nullable<Color> color)>, Boolean, Boolean, Double, Transform, Boolean, Guid, String)

Create a collection of points.

Declaration
[JsonConstructor]
public ModelArrows(IList<(Vector3 location, Vector3 direction, double magnitude, Color? color)> vectors = null, bool arrowAtStart = false, bool arrowAtEnd = true, double arrowAngle = 60, Transform transform = null, bool isElementDefinition = false, Guid id = default(Guid), string name = null)
Parameters
Type Name Description
System.Collections.Generic.IList<System.ValueTuple<Vector3, Vector3, System.Double, System.Nullable<Color>>> vectors

A collection of tuples specifying the origin, direction, and the magnitude of the arrows.
System.Boolean arrowAtStart

Should an arrow head be drawn at the start?
System.Boolean arrowAtEnd

Should an arrow head be drawn at the end?
System.Double arrowAngle

The angle of the arrow head.
Transform transform

The model arrows' transform.
System.Boolean isElementDefinition

Is this an element definition?
System.Guid id

The id of the model arrows.
System.String name

The name of the model arrows.

Properties

Vectors

A collection of tuples specifying the origin, magnitude, and color of the arrows.

Declaration
public IList<(Vector3 origin, Vector3 direction, double magnitude, Color? color)> Vectors { get; set; }
Property Value
Type Description

Methods

TryToGraphicsBuffers(out List<GraphicsBuffers>, out String, out Nullable<MeshPrimitive.ModeEnum>)

Get graphics buffers and other metadata required to modify a GLB.

Declaration
public override bool TryToGraphicsBuffers(out List<GraphicsBuffers> graphicsBuffers, out string id, out MeshPrimitive.ModeEnum? mode)
