SceneGraphDisplay Properties Table

Property ID	Short Name (English)	Description	R/W	RTE
50F27405	AutoProjection	Reads or writes whether LabVIEW automatically updates the projection mode for the scene. If set to Orthographic or Perspective, LabVIEW sets up an appropriate projection based on the scene or the size of the control.	R/W	X
50F27401	BackgroundColor	Reads or writes the RGBA color value for the background of the 3D scene. Elements: Name Description Red Indicates the red value. Valid values include 0 through 1. Green Indicates the green value. Valid values include 0 through 1. Blue Indicates the blue value. Valid values include 0 through 1. Alpha Indicates the Alpha value. Set the Alpha value on the background of a 3D scene only for blending. Setting this value does not make the background of the 3D picture control transparent. Valid values include 0 through 1.	R/W	X
50F2740C	CameraController.AutoRedraw	Reads or writes if this control becomes invalid when you use the camera controller.	R/W	X
50F27404	CameraController.Type	Reads or writes the configuration of the scene camera. Click and hold the left mouse button and drag the cursor to operate the camera.	R/W	X
50F27406	ContentBounds	Reads or writes the bounds for the 3D picture control in which LabVIEW renders a 3D scene.	R/W	X
50F27408	ContentBounds.Height	Reads or writes the height of the 3D picture control. This property is an element of the Content Bounds property.	R/W	X
50F27407	ContentBounds.Width	Reads or writes the width of the 3D picture control. This property is an element of the Content Bounds property.	R/W	X
50F27409	ContentPosition	Reads or writes the position of the area in which content appears in the 3D picture control.	R	X
50F2740A	ContentPosition.Horizontal	Reads or writes the horizontal position of the area in which content appears in the 3D picture control. This property is an element of the Content Position property.	R	X
50F2740B	ContentPosition.Vertical	Reads or writes the vertical position of the area in which content appears in the 3D picture control. This property is an element of the Content Position property.	R	X
50F27400	ModelViewMatrix	Reads or writes a matrix that contains the translation, rotation, and scale values for the 3D scene that appears in the 3D picture control. This property returns a 4 x 4 array of single-precision numbers.	R/W	X
50F27403	ProjectionMatrix	Read or writes the matrix that represents the transformations LabVIEW uses to project the scene in the 3D picture control viewer. This property returns a 4 x 4 array of single-precision numbers.	R/W	X

SceneGraphDisplay Methods Table

Method ID	Short Name (English)	Description	RTE
50F27009	AutoFocus	Positions the camera to view all 3D scene objects in the front panel window.	X
50F27006	Pick Model	Casts a ray through a 3D scene at the Point coordinate and determines which models in the scene intersect with the ray.	X
50F27008	PickPoint	Given an x and y coordinate, casts a ray through the 3D scene and returns the x, y, and z-coordinates of the first object the ray intersects.	X
50F27005	Projection.Frustum	Sets coordinates to render the scene in a frustum-shaped view. This projection causes objects farther from the camera to appear smaller.	X
50F27002	Projection.Orthographic	Sets coordinates to render the scene in a box-shaped view. The distance of the camera from the objects does not affect the size of the objects in this view.	X
50F27003	Projection.Perspective	Sets coordinates to render the scene in a frustum-shaped view, where you specify an angle for the horizontal and vertical viewing fields. This projection causes objects closer to the camera to appear larger in size. This method is similar to the Projection:Frustum method.	X
50F27007	Redraw	Redraws the 3D scene in the 3D picture control.	X
50F27004	Render to Image	Returns an image of the scene.	X
50F27000	Setup Camera	Specifies the position of the camera relative to the scene. This method modifies the ModelView Matrix.	X
50F2700A	WindowToObjectCoords	Converts a point in window coordinates to points in object coordinates on the near and far clip planes of the view.	X
