Echo Display Environment

Echo Help

The Echo Help Window displays any information pertinent to the opertation the user is carrying out. Also, this window provides feedback on the cursor position and any measurements.

Echo Help Window

Echo Wireframe

A wireframe view of the scanned object appears in this window. The primary function of the Echo Wireframe Window is to provide a window to allow quick and intuitive navigation. The scanned object can be zoomed, rotated, or panned in this window.

Echo Wireframe Window

Menu

To activate the Echo Wireframe Menu, depress Button 3 (right mouse button). In this menu, you will find the navigational commands required to ensure a complete and accurate orientation of any object that you scan.

Please note that upon completion of the desired reorientation, you must select Redraw from the Echo Render window pop-up menu. Below are the most commonly used menu selections and their functions.

Echo Wireframe Menu

Rotate:
After you select this item, move the mouse up/down or left/right to rotate the object. Click any mouse button to exit the Rotate Mode.

Zoom:
Select this item, then move the mouse upward to zoom in on the object. Move the mouse downward to zoom away from the object. Click any mouse button to exit this mode.

Pan:
Move the mouse left-right to pan along the x-axis, or up/down to pan along the y-axis after selecting this menu item. This mode can be exited by pressing any mouse button.

Help:

Exit:
To leave the Display Mode, select this menu item.

Echo Render

The Echo Render window is where the object is displayed in a shaded view. The user can select from several display modes for a better representation of the object.

The Echo Render window also provides access to basic editing and measurement functions.

Echo Render Window

Menu

To activate the Echo Render menu, depress Button 3 (right mouse button). In this menu, you will find the commands needed to accurately display an object, edit the range data, and take measurements. Below are the most commonly used menu selections and their functions.

Echo Render Menu

Redraw:
Select this menu item to update the view in the Echo Render Window. This is a necessary step after any change in the Echo Wireframe Window.

Meter Points:
This choice has two (2) modes, measurement and editing:

• Measurement Mode: While in any display mode, depress Button 2 to select a point. The various values for this point will be displayed on the screen in Shell Window. If you select additional points, Echo will return to you the distance between the points.

• Editing Mode: Select Image Colors from the Texture Map Selection in the Echo Render window pop-up menu. To select points for editing, hold down Button 1 and drag across the points that you wish to select.

Surface Tools:
This selection will present the user with the main editing functions in Echo. This item allows you to change the Selection Cursor size, as well as access the "Select None," "Select Region," and "Select Inverse" functions. You can also choose to void selected data points using the selections in this menu.

View Window

The View window allows the user to adjust the threshold of light on the CCD that is registered as a valid data point. To facilitate the most accurate setting of the threshold, or sensitivity, the View window provides the user with several methods of viewing the laser stripe in real-time, as well as some rudimentary motion commands.

View Window

View Menu

The View Menu provides access to the different viewing modes, and to commands that can reorient the motion platform to allow the user to view the object from different angles and positions.

View Menu

Profile

The Profile mode displays a real time view of the laser stripe, as seen by the CCD. This view is displayed with the individual sample points connected so that a continuous line is shown. This is the default display method, and is most useful for setting the sensitivity.

Dots

As in Profile mode, the laser stripe is drawn in real time. However, only the individual data points are drawn in the View window, and they are not connected. This view is the most accurate with regards to the actual data that is being sensed by the CCD.

Colors

The Colors mode will display a view of the colors being sensed by the color-camera CCD in real time.

Luminance

When the Luminance mode is enabled, a display of the luminance values for each data point is presented. This mode is especially useful to ensure that the CCD is not oversaturated.

Laser On

This menu selection turns the laser on, if it has gone off. If the laser turns off, it is most likely due to the 30-second time limit that is coded into our scanners for safety purposes.

Laser Off

The Laser Off selection will turn the laser off, if it is currently on.

Hold

The menu selection, Hold, simply freezes the display in the View window and it will not be updated until one of the other modes (Profile, Dots, Colors, or Luminance) is selected.

Scripts

The Scripts selection opens a sub-menu with choices for moving the rotary platform to obtain views from several angles. This capability ensures that the user has the proper sensitivity setting.

There are four choices in the sub-menu; Turn 0, Turn 90, Turn 180, and Turn 270. The degree value is in absolute terms, so 0 degrees is always the home position, 90 is 90° degrees from 0° in a clockwise fashion, etc.

Quit

This menu item will exit the View Mode. Any sensitivity level changes that the user has specified will be saved automatically.

Shell Window

The Shell window provides the user with the power to access the UNIX environment from within Echo. The user can also issue specific Echo commands using the is command-line interface. For a more complete description of the Echo commands, please consult the Advanced Usage Section of this User Guide.
