Point Cloud

Point clouds can be used to represent 3D scans and in the future can represent particles. Each point can store data in a set of Attributes.

屬性

Attributes

The Attributes panel contains different point cloud characteristics such as the position and size of points. Use the List View to manage attributes.

Attribute Types

See Built-In Attributes for information about common attributes.

Name	Type	Domain	Notes
`position`	Vector	Point	Built-in attribute describing vertex or point locations, in the modifier object's transform space.
`radius`	Float	Point	The radius of each point.
`color`	Color	Point	The color of each point.
`id`	Integer	Point	A unique identifier given to each particle.
`velocity`	Vector	Point	The speed and direction that the particle is traveling.

Custom Attributes

Custom attribute can be given to particles to hold a custom characteristic.

Name

The name of the attribute.

Data Type

The type of data to store in the attribute.

Float: Floating-point value
Integer: 32-bit integer
Vector: 3D vector with floating-point values
色彩: RGBA color with floating-point precision
Byte Color: RGBA color with 8-bit precision
String: Text string

Domain

The type of element the attribute is stored in. Currently, attributes can only be stored per Point.

Custom Properties

See the Custom Properties page for more information.

Editing

Currently, not much can be done with point clouds; however, they can be converted to/from meshes.
