Colour Mapping

Function

This command allows for a global override of point cloud coloring. Initial point cloud coloring can be replaced by true color or intensity mapping (if available).

Procedure

To override point cloud color mapping:

1. Click on the icon or type CWCOLORMAP at the CAD command line and press Enter. The Point Cloud Color Mapping dialog appears.

2. Make a selection from the Global Color Mapping list.

• Select No Override to display each point cloud using its own setting or layer override.

• Select Intensity Mapping to display all point clouds with intensity-mapped colors. If intensity data is not available, IMS Map360 attempts to use true color data (if available), then a single color.

• Select True Color to display all point clouds with true color mapped into the CAD palette. If true color data is not present (It must be scanned with a calibrated scanner.) for a point cloud, the point cloud will instead use intensity data (if available), then a single color.

3. If Intensity Mapping is chosen from the Global Color Mapping list, select a mapping Color Scheme, and then adjust the intensity mapping range if desired.

• From the Color Scheme drop-down list, select Grayscale, Multi-Hue, or a scaled individual color with which to display the intensity map.

• To adjust the intensity mapping range, enter a value for the lowest intensity (to be mapped to the low end of the selected color scheme in the Minimum field), and then enter a value (for the highest intensity to be mapped to the high end of the selected color) in the Maximum field. Intensities lower than the minimum or higher than the maximum are given the minimum's or maximum’s color respectively. The Minimum and Maximum settings typically range from 0 to 1. These values correspond to the range from dark to bright (from red through yellow and green to blue for the Multi-Hue setting). For a greater difference in shades, set a more narrow range.
