How to assign and manage color mapping for point cloud attachments that contain intensity data.
Some types of scan files contain color intensity data that can be retained in the point cloud. These file types include LAS, PTG, PTS, PTX, CLR and CL3.
Assign Colors to Map the Point Cloud Intensity
- In the drawing area, select a point cloud that contains intensity data.
- Click Point Cloud tab
Visualization panel Stylization (flyout) Intensity.
- Click Point Cloud tab Visualization panel Intensity Color Mapping.
At the Command prompt, enter POINTCLOUDINTENSITYEDIT. - In the Point Cloud Intensity Color Mapping dialog box, adjust the following settings:
- Color scheme. Select a color scheme to help illustrate the point cloud intensity mapping. Colors range from Spectrum (for use with complex point clouds that have many point groups) to grayscale and single colors (for less complicated point clouds).
- Color ramp. Drag the sliders to define the color range to use in the mapping.
- Intensity minimum and maximum. Enter values between 0.000 and 1.000 to specify the percentage of intensity values to be displayed using the color map stylization. These values represent the high and low values of the entire range of intensity values associated with the selected point cloud.
Points with intensity values that are outside the limits that you specify are displayed using the original scan colors.
- Click Apply to test how the settings affect the selected point cloud.
Change the Point Cloud Intensity Color Scheme (Properties Palette)
- If the Properties window is not displayed, select any object. Right-click the object and select Properties.
- In the drawing area, select the point cloud.
- In the Properties window Point Cloud Visualization Intensity Color Scheme box, select a different option.
