Properties

HitTestThickness

Used only for point/line hit test

public double HitTestThickness { get; set; }

Property Value

double

Methods

CanRender(RenderContext)

Determine if this can be rendered.

protected override bool CanRender(RenderContext context)

Parameters

context RenderContext

Returns

bool

CreateRasterState()

Create raster state description.

protected override RasterizerStateDescription CreateRasterState()

Returns

RasterizerStateDescription

DistanceRayToPoint(Ray, Vector3)

Distances the ray to point.

public static double DistanceRayToPoint(Ray r, Vector3 p)

Parameters

r Ray

The r.

p Vector3

The p.

Returns

double

OnCheckGeometry(Geometry3D?)

Called when [check geometry].

protected override bool OnCheckGeometry(Geometry3D? geometry)

Parameters

geometry Geometry3D

The geometry.

Returns

bool

OnCreateBufferModel(Guid, Geometry3D?)

Called when [create buffer model].

protected override IAttachableBufferModel OnCreateBufferModel(Guid modelGuid, Geometry3D? geometry)

Parameters

modelGuid Guid
geometry Geometry3D

Returns

IAttachableBufferModel

OnCreateRenderCore()

Called when [create render core].

protected override RenderCore OnCreateRenderCore()

Returns

RenderCore

OnCreateRenderTechnique(IEffectsManager)

Override this function to set render technique during Attach Host.

If OnSetRenderTechnique is set, then OnSetRenderTechnique instead of OnCreateRenderTechnique(IEffectsManager) function will be called.

protected override IRenderTechnique? OnCreateRenderTechnique(IEffectsManager effectsManager)

Parameters

effectsManager IEffectsManager

Returns

IRenderTechnique

Return RenderTechnique

OnHitTest(HitTestContext?, Matrix4x4, ref List<HitTestResult>)

Called when [hit test].

protected override bool OnHitTest(HitTestContext? context, Matrix4x4 totalModelMatrix, ref List<HitTestResult> hits)

Parameters

context HitTestContext

The context.

totalModelMatrix Matrix4x4

The total model matrix.

hits List<HitTestResult>

The hits.

Returns

bool

PreHitTestOnBounds(HitTestContext?)

Pre hit test on BoundsWithTransform and BoundsSphereWithTransform. If return false, OnHitTest(HitTestContext?, Matrix4x4, ref List<HitTestResult>) will not be called.

protected override bool PreHitTestOnBounds(HitTestContext? context)

Parameters

context HitTestContext

Returns

bool
