Point Clouds Properties
This page documents the properties available for point clouds in VRGS. These properties appear in the Properties panel when an object of this type is selected.

Point Cloud From Spherical Scanner
Property name: From Spherical Scanner

Point Cloud Name
Property name: Name
Description Name of the point cloud
What it does

Point Cloud Points
Property name: Points
Description Number of points
What it does
Number of points
Point Cloud Show Normals
Property name: Show Normals (in the Normals group)
Description Draw each point's normal as a short line: cyan where it faces up, orange where it faces down, fading from base to tip
What it does
Draws each point's stored normal as a short line in the Vulkan 3D view. An up-facing
normal is cyan and a down-facing one orange, and each line fades from a light base to a
strong tip. A cloud of more than 2 million points shows every k-th normal, so the count
stays at about 2 million and the same points come back as you work. Deleted, hidden and
filtered-out points show none. Off by default. The OpenGL view does not draw them.
The Normals group appears only when a loaded cloud has normals of its own: an SfM dense cloud does, and so does a cloud that has had tensor analysis or been meshed with Poisson.
When to use it
Use it to check a cloud's normals before meshing. A flipped patch reads as a block of the
wrong colour among its neighbours.
Point Cloud Normal Length
Property name: Normal Length (in the Normals group)
Description Length of each normal line; 0 sizes it to the cloud
What it does
The length of each Show Normals line, in model units. 0, the default, makes it
0.5 % of the cloud's bounding-box diagonal.
When to use it
Raise it to read the normals from further away, or lower it on a dense cloud whose lines
run into one another.
