Constructors

HitTestContext(IRenderMatrices?, Ray, Vector2)

Initializes a new instance of the HitTestContext class.

public HitTestContext(IRenderMatrices? metrices, Ray rayWS, Vector2 hitSP)

Parameters

metrices IRenderMatrices

The render metrices.

rayWS Ray

The ray in world space.

hitSP Vector2

The hit point on screen space. Pass in the hit point on viewport region directly.

Do not scale with DpiScale factor.

HitTestContext(IRenderMatrices?, ref Ray)

Initializes a new instance of the HitTestContext class. This calculates screen hit point automatically from metrices and world space ray.

public HitTestContext(IRenderMatrices? metrices, ref Ray rayWS)

Parameters

metrices IRenderMatrices

The render metrices.

rayWS Ray

The ray in world space.

HitTestContext(IRenderMatrices?, ref Ray, ref Vector2)

Initializes a new instance of the HitTestContext class.

public HitTestContext(IRenderMatrices? metrices, ref Ray rayWS, ref Vector2 hitSP)

Parameters

metrices IRenderMatrices

The render metrices.

rayWS Ray

The ray in world space.

hitSP Vector2

The hit point on screen space. Pass in the hit point on viewport region directly.

Do not scale with DpiScale factor.

HitTestContext(IRenderMatrices?, ref Vector2)

Initializes a new instance of the HitTestContext class. This calculates ray in world space automatically from metrices and hit point.

public HitTestContext(IRenderMatrices? metrices, ref Vector2 hitSP)

Parameters

metrices IRenderMatrices

The render metrices.

hitSP Vector2

Screen hit point. Pass in the hit point on viewport region directly.

Do not scale with DpiScale factor.

Properties

HitPointSP

Gets or sets the hit point on screen space. This is the hit point on viewport region without DpiScaled coordinate.

public Vector2 HitPointSP { get; set; }

Property Value

Vector2

The screen hit point.

RayWS

Gets or sets the ray in world space.

public Ray RayWS { get; set; }

Property Value

Ray

The ray.

RenderMatrices

Gets or sets the render matrices. This is only needed for line/point hit test.

public IRenderMatrices? RenderMatrices { get; set; }

Property Value

IRenderMatrices

The render matrices.
