About Point Cloud Color Stylization and Visual Effects
Stylize point clouds to help you analyze features within the point cloud. You can
stylize based on the original scan colors, the AutoCAD object color, the normal direction
of points, and if the required data exists in the point could, you can also stylize
based on laser pulse return intensity, elevation, or LAS classification data.
Stylization Options
- Object Color. Stylizes each point based on the point cloud object color property.
NOTE:There may be variations of the object color depending upon lighting settings and whether
normal information is stored with the points.
- Normal.Stylizes each point based on the normal direction of the point based on a default
color scheme that is not editable. When a point cloud is captured during scanning,
a normal direction vector can be calculated for each point based upon the surrounding
points. In this way, scanner software infers planar or curved areas; the normal of
a point is then a vector perpendicular to the inferred plane or curved surface.Using built-in colors assigned to the X, Y, and Z directions of the point cloud, normal stylization assigns one of these colors to
each point, based on the direction of the normal for that point. The nearer the normal
is to the X, Y, or Z direction in the drawing, the closer the point color is to the color assigned to
that axis.
- Intensity.Stylizes each point based on the laser pulse return intensity value. Scanners identify
an intensity value for each point during the capture process. Intensity is a measure
of point reflectivity, which can vary depending upon color, surface texture, surface
angle, and the environment.
- Elevation. Stylizes each point based on its Z value.
- Classification. Stylizes each point based on its standard LAS classification (as defined by the American
Society of Photogrammetry and Remote Sensing). Scanner software that performs post-processing
on scan files allows users to assign a classification to each point, such as ground,
building, water, vegetation, roads, and transmission wires.
different stylizations. For example, if there is no intensity data in the attached
scans, Intensity is grayed out in the stylization dropdown. If a point cloud contains
some points that can be colored based on the selected style and some points that cannot,
the style is applied to the points that can be stylized.
Color Schemes
You can customize the color schemes for Intensity, Elevation, and Classification stylizations
with the POINTCLOUDCOLORMAP command.
For Intensity and Elevation, you can edit the number of colors and individual colors
that make up the color ramp, and you can specify whether to show it as a gradient
or as bands of individual colors. You can also change the range of points to which
the color scheme applies, and specify how to display the out-of-range points.
For Classification, you can change the color assigned to each classification category.
Visual Effects
In addition to applying color stylization, you can also specify settings for lighting
and shading.
