3D Stereo Viewer (3DS)

Type: Graphics Tools

 

Allows user to view VrOne vector data dynamically using 3D stereo perspectives.

Detailed Description

The 3D viewer is a display-only window that allows vector data to be viewed from any perspective. The vector data may be scaled and rotated in real-time, allowing quick analysis of the vector data. The Z value of the vectors can be exaggerated to give a clearer view of terrain changes. When viewing triangles (any closed line with 3 points), hidden lines may be removed from view.

This is intended for small to medium datasets. Trying to load 10 million LiDAR points for viewing will probably make the viewer unresponsive.

The following mouse controls can be used to change the view.

Remove hidden lines

Specifies whether triangles (closed lines with 3 points) hide lines that are behind them..

Show Axis Icon

Specifies whether any axis icon will be displayed in the bottom left hand corner of the window. The above sample dialog has the icon turned on, showing the current direction of X,Y,Z.

Track Graphics Cursor

Specifies whether a cross-shaped cursor is displayed at the current ground location of the VrOne graphics cursor. The cursor will be displayed dynamically as the VrOne graphics cursor is moved in one of the VrOne graphics windows.

Search Layers

Specifies which layers in the currently open workspaces are displayed.

Point Size

Controls the size (in pixels) that points are to be displayed. All VrOne symbols are displayed as single points in the 3D viewer.

Background Color

Displays a color selection dialog to select a color for the background of the 3D viewer display area.

Face Color

Displays a color selection dialog to select a color for the face of triangles.

Cursor Color

Displays a color selection dialog to select a color for the cursor (if cursor tracking is on).

Update

Press this button after changing the search layers to reload the vectors using the current layer number line.
