Nút Chuyển Đổi Alpha.

The Distribute Points on Faces node places points on the surface of the input geometry object. Point, corner and polygon attributes of the input geometry are transferred to the generated points. That includes vertex weights and UV maps. Additionally, the node has Normal and Rotation outputs.

The node also generates a stable ID, stored in the built-in id attribute, used as a stable identifier for each point. When the mesh is deformed or the density changes the values will be consistent for each remaining point. This attribute is used in the Random Value and Instance on Points nodes.

Đầu Vào

Hình Dạng

Standard geometry input.

Ghi chú

The input geometry must contain a mesh with faces.

Lựa Chọn

The selection of which face corners should be considered for point distribution.

Giá trị Tối Đa của khoảng cách

The minimal distance points can have to each other. This option is only available for the Poisson Disk distribution method. At its default value of zero, the node's behavior is the same as it is in Random mode, because none of the internally generated points are removed.

Giá trị Tối Đa của Tỷ Trọng/Mật Độ/Trù Mật

The point density for the point distribution. The unit is in number of points per square meter. This value is multiplied by the values from the Density input. Only available in Poisson Disk mode.

Ghi chú

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.

Tỷ Trọng

The point density for the point distribution. The unit is in number of points per square meter. This value is multiplied by the values from the Density Attribute.

In Poisson Disk mode, this value is multiplied by the Density Max input for the final density.

Mầm

The random Seed to use when generating points.

Tính Chất

Phương Pháp Phân Bố

Ngẫu Nhiên

Distribute points randomly on the surface. This is the fastest distribution method.

Poisson Hình Đĩa

Distribute points randomly on the surface while taking a minimum distance into account.

Đầu Ra

Hình Dạng

Generated points. Named attributes are copied to the result mesh, along with the data in the other attribute field outputs.

Pháp tuyến/B.Thg

The Normal of the triangle on which each point is scattered.

Xoay Chiều:

An XYZ Euler rotation built from the normal attribute for convenience. Such a value can also be built from the normal with the Chế Độ Euler. Keep in mind that the Z axis of the result rotation will be arbitrary, since the mesh normal used to create the rotation does not have enough information to set all three rotation axes.
