Description

Colorizes the point cloud based on a range of colors. You can define the options through the Point Cloud Color Map command context panel, as well as through the Command line.

Method

Run the command to display the Point Cloud Color Map command context panel, then specify the color map parameters.

Options within the command context panel

Note: The options within the command context panel reflect the options within the Command line.

Color Stylization
Specifies the color stylization. Depending on the chosen color stylization, different setting are further available.
  • Scan: assigns colors based on the color data collected by the scan.
  • Object: uses the color assigned to the point cloud entity in the DWG file. This color can be retrieved and changed via the Properties panel with the point cloud selected.
  • Elevation: assigns colors based on the elevation of the points using the specified color map.

    The predefined color schemes for this color stylization are Hydro, Grayscale, Earth, Blues, Greens, Reds, and Spectrum.

  • Intensities: assigns colors according to their intensity value using the specified color map.
    Note: When the point cloud file does not contain any intensity data, the colors are assigned by height, regardless of the option you select.

    The predefined color schemes for this color stylization are Hydro, Grayscale, Earth, Blues, Greens, Reds, and Spectrum.

  • Normals: assigns colors to points based on their normals using the specified color map.
  • Classification: assigns colors to points based on their classification using the specified color map.

    The predefined color schemes for this color stylization are Lidar Classifications and 3DR Classifications.

    Note: If the points are not classified, use the POINTCLOUDCLASSIFY command before using the POINTCLOUDCOLORMAP command.
  • X-Ray: adds transparency at the point cloud entity level.

    Allows you to trace a point cloud and create 2D drawings based on orthographic views. See also the SECTIONPLANE command and ACTIVATESECTIONVIEW command articles.

    Note: For Linux, force BricsCAD® to run on the GPU so this feature can perform well.
Color Scheme
  • Hydro: assigns a range of colors from deep sky blue to very dark blue.
  • Grayscale: assigns a range of colors from light gray to dark gray.
  • Earth: assigns a range of colors from light brown to dark brown.
  • Blues: assigns a range of colors from blue to very dark blue.
  • Greens: assigns a range of colors from light green to dark green.
  • Reds: assigns a range of colors from light red to dark red.
  • Spectrum: assigns a range of colors based across the color spectrum.
Intensity Remap
By default this value is set to None. In order to improve the intensity contrast in the darker areas, select one of the two functions to be applied to the intensities first.
Gamma is a power function (the square root) of the input intensities.
Shadows is a function applied to input intensities, also to get better contrast in darker areas before mapping them to color.
Use Gradient
Specifies whether to use a gradient or not.
No: no gradient is applied, the colorization of the point cloud is defined by using value intervals defined by the number of colors used in the scheme. The desired number of colors needs to be specified.
Yes: a gradient will be applied to the point cloud points.
Use Inverted
Specifies whether the order of the colors in the selected color scheme should be used inverted.
No: the order of the colors specified in the selected color scheme is used.
Yes: the inverted order of the colors specified in the selected color scheme is used.
Range
Determines the min and max values for scaling Intensity and Elevation used in color maps.
Use full data range
When turned On, all visible points are taken into account to determine the min and max values. Turn Off to manually set these values.
Out of range values
Specifies the colors assigned to points found out of the specified range.
Scan
Assigns the original RGB color to points found out of the specified range.
MinMax
Assigns the min and max colors to points found below or above the specified range.
Intensity min
Sets the intensity minimum value.
Intensity max
Sets the intensity maximum value.
Chosen color scheme
Allows you to edit an existing color scheme or to create a new one. These maps are stored in the DWG file in an AutoCAD® compatible way.
Click the colors listed in the table to select new ones using the Choose a color dialog box.
Number of colors
Specifies the number of colors used in the color scheme. Enter a value to change this number.
Name
Specifies the name of a new custom color scheme.

Click the Save button () to add the custom scheme to the Color Scheme drop-down list.

Click the Remove button () to delete the selected custom scheme.

Live preview
When checked, modifications are automatically applied to the point cloud.
Note: When this option is not checked, changes can be applied manually by pressing Apply.
