Class DemoPickable

Namespace

Sample.Disp

Assembly

Hi.Sample.Wpf.dll

Demonstrates creation of pickable 3D geometry at the primitive level. Shows how to assign picking IDs directly to geometry vertices and create interactive triangles. Uses a lower-level approach than the Pickable base class for more precise control.

Constructors

DemoPickable()

Initializes a new instance of DemoPickable. Creates a pickable triangle with a specific picking ID for user interaction.

public DemoPickable()

Methods

Display(Bind)

Display function called in DispEngine rendering loop.

public void Display(Bind bind)

Parameters

bind Bind

Bind with DispEngine. See Bind.

ExpandToBox3d(Box3d)

Expands the destination box. This function is usually used to compute the bounding box of elements.

public void ExpandToBox3d(Box3d dst)

Parameters

dst Box3d

Destination box

Main()

Entry point for the DemoPickable example. Creates and displays a pickable triangle that can respond to mouse events. Demonstrates integration of picking functionality with geometric primitives.
