Laser Data

Displays rendered Laser Survey Data (XGOEM) alongside the modelled data.
The appearance of the laser survey is inherited from a Point Cloud Volume Representation Set (LAVOST) element which stores a list of representation style elements. Each representation element references an Area Definition (AREADE) or Demolition Package (DEMOPA) element in which the volume of laser survey is rendered. AREADE and DEMOPA elements are stored in the Design (DESI) database and cannot be modified in the DRAW application.
The drawing output containing laser survey is depth buffered with modelled elements. All modelled elements that are in front of the laser survey will obscure the survey, and all elements behind the survey will be obscured by the survey.
The first time the Point Cloud Volumes window displays for a view, the DRAW application checks that the view references a point cloud volume representation set. If the view does not reference a point cloud volume representation set, a confirm window displays asking you to create one.
Click Yes to create a point cloud volume representation set. Click No to define that the view is not associated with a point cloud volume representation set.
The Point Cloud Volumes window displays the area definitions and demolition packages that have been defined in Model. When an area definition or demolition package is selected, the selection is highlighted in the 2D or 3D view.

Select LAVOST |
Allows you to modify the point cloud volume representation set used to define the appearance of the laser survey. Click to display the Select Point Cloud Volume Representation Set window.
You can browse and select the required point cloud volume representation set element. Click Select to apply the selected point cloud volume representation set element. Click Cancel to discard any changes and close the Select Point Cloud Volume Representation Set window. |

Detail Laser Data |
Click to optimise the display resolution of the laser survey within the area definition or demolition package volume. Repeat the command to turn off the display optimisation. |
|
|
Highlight Laser Data |
Click to highlight detailed laser survey data within the area definition or demolition package volume. The default highlight colour is pink and cannot be modified. Repeat the command to remove the highlight from the detailed laser survey data volume. |

|
Specify Highlight Colour |
Click to modify the colour of highlighted laser survey data within the area definition or demolition package volume. Multiple colours can be used to highlight the area definition or demolition package volume. Select a colour from the colour palette. The laser survey data is not highlighted as a solid colour, the colour is applied as a colour ramp to the selected volume. If the highlight was to be displayed as a solid colour, depth cues could be difficult for the user and the laser survey data could appear as a flat representation. As colour ramps are applied to the laser survey data, some colours may not appear to contrast well with the laser survey data or other highlight colours. It is recommended that highlight colours are restricted to a limited discernible palette. |

Mask Laser Data |
Click to remove detailed laser survey data within the area definition or demolition package volume. Repeat the command to remove the mask from the detailed laser survey data volume. |
Export and Print Resolution
Sets the laser survey final output quality.
The export/print resolution can be modified to alter the output using the Properties window. Refer to Properties for further information.

Point Cloud Drawing Resolution (dpi) |
The dots per inch (dpi) resolution defines the amount of dots that are printed/exported on the output drawing per square inch. Input a value in the field to modify the dpi resolution for laser survey. For example, input 50 in the field to print/export at 50 dpi. The laser survey display is less detailed and solid (background model elements are not visible). Input 600 in the field to print/export at 600 dpi. The laser survey display is more detailed and translucent (background model elements are visible). |
