点分布¶

The Point Distribute Node.¶

The Point Distribute node places points on the surface of the input geometry object.

输入¶

几何数据(Geometry): Standard geometry input.

Note

The input geometry must contain a mesh with faces.
Distance Min: The minimal distance points can have to each other. This option is only available on distribution methods that support it.
Density Max: The point density for the point distribution. The units are number of points per square meter. This value is multiplied by the values from the Density Attribute.

Note

This will be capped on distributions by the Distance Min option. If the density is greater than what the minimal distance allows, no new points will be added after this threshold has been passed.
密度属性: The name of the attribute to use for influencing the point density. The values of this attribute are multiplied by Density Max for the final density value.

分布方法

随机: Distribute points randomly on the surface.
泊松盘: Distribute points more evenly on the XY plane, then project them to the mesh along the Z axis.

随机种

The random Seed to use when generating points.

几何数据(Geometry)

Generated points. Several attributes are created on the output points based on the input mesh:

id (int): An identifier for each point used for stability when the mesh is deformed, used in the 属性随机化 and 点实例 nodes.

normal (vector): The Normal of the triangle on which each point is scattered.

rotation (vector): An XYZ Euler rotation built from the normal attribute for convenience.
