3D Viewer (3D, 3DS)

Type: Graphics Tools

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

Start the command using ‘3D’ for normal viewing, or start it using ‘3DS’ to view the vectors in stereo on systems that support stereo viewing.

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.

Left button	Up/Down movement=X rotation, Left/Right movement=Y rotation
Right button	Up/Down movement=Z rotation
Shift-Left button	Pan
Scroll	Zoom In/Out
Shift-Scroll	Faster Zoom In/Out
Ctrl-Scroll	Exaggerate Z scale

3D Viewer

Remove hidden lines

If this is on, any triangles (closed lines with 3 points) will hide lines that are behind them..

Show Axis Icon

If this is on, any axis icon will be displaye din 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

If this is on, then a cross-shaped cursor will be 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

This is a number line that specified what layers in the currently open workspaces will be displayed.

Point Size

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

Background Color

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

Face Color

Displays a color selection dialog allowing a color to be set for the face of triangles.

Cursor Color

Displays a color selection dialog allowing a color to be set 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.
