SceneGraphDisplay Properties Table

Property ID	Long Name (English)	Description	R/W	RTE
50F27400	ModelView Matrix	Reads or writes a matrix that contains the translation, rotation, and scale values for the 3D scene that appears in the 3D picture control.	Read/Write	Yes
50F27401	Background Color	Reads or writes the RGBA color value for the background of the 3D scene.	Read/Write	Yes
50F27403	Projection Matrix	Read or writes the matrix that represents the transformations LabVIEW uses to project the scene in the 3D picture control viewer.	Read/Write	Yes
50F27404	Camera Controller: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.	Read/Write	Yes
50F27405	Automatic Projection Mode	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.	Read/Write	Yes
50F27406	Content Bounds	Reads or writes the bounds for the 3D picture control in which LabVIEW renders a 3D scene.	Read/Write	Yes
50F27407	Content Bounds:Width	Reads or writes the width of the 3D picture control.	Read/Write	Yes
50F27408	Content Bounds:Height	Reads or writes the height of the 3D picture control.	Read/Write	Yes
50F27409	Content Position	Reads or writes the position of the area in which content appears in the 3D picture control.	Read Only	Yes
50F2740A	Content Position:Horizontal	Reads or writes the horizontal position of the area in which content appears in the 3D picture control.	Read Only	Yes
50F2740B	Content Position:Vertical	Reads or writes the vertical position of the area in which content appears in the 3D picture control.	Read Only	Yes
50F2740C	Camera Controller:Auto Redraw	Reads or writes if this control becomes invalid when you use the camera controller.	Read/Write	Yes

SceneGraphDisplay Methods Table

Method ID	Long Name (English)	Description	RTE
50F27000	Setup Camera	Specifies the position of the camera relative to the scene. This method modifies the ModelView Matrix.	Yes (Read/Write)
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.	Yes (Read/Write)
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.	Yes (Read/Write)
50F27004	Render to Image	Returns an image of the scene.	Yes (Read/Write)
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.	Yes (Read/Write)
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.	Yes (Read/Write)
50F27007	Redraw	Redraws the 3D scene in the 3D picture control.	Yes (Read/Write)
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.	Yes (Read/Write)
50F27009	AutoFocus	Positions the camera to view all 3D scene objects in the front panel window.	Yes (Read/Write)
50F2700A	WindowToObjectCoords	Converts a point in window coordinates to points in object coordinates on the near and far clip planes of the view.	Yes (Read/Write)
