Nút Mật Độ Điểm -- Point Density Node

Point Density Node.

The Point Density node is used to add volumetric points for each particle or vertex of another object.

Đầu Vào -- Inputs

Vectơ -- Vector

Texture coordinate to sample texture at; defaults to global position (Position output of Geometry node) if the socket is left unconnected.

Tính Chất -- Properties

Point Data

Where to get points from.

Hệ Thống Hạt -- Particle System

Use each particle position from the specified particle system.

Điểm Đỉnh của Vật Thể -- Object Vertices

Use each vertex position from the specified object.

Vật Thể -- Object

Which object's vertices or particle system will be used.

Hệ Thống Hạt -- Particle System

Particle positions from this system will be used.

Không Gian -- Space

The coordinate system for mapping points.

Không Gian Thế Giới -- World Space

Map each point exactly where the source particle/vertex is.

Không Gian Vật Thể -- Object Space

Fit the points from the source particles/vertices inside the bounding box of the object with the point density texture.

Bán Kính -- Radius

Size of the points.

Nội Suy -- Interpolation

Texel filtering type.

Gần Nhất -- Closest

No interpolation, use nearest texel. Produces blocky looking points.

Tuyến Tính -- Linear

Interpolate linearly between texels, producing soft, round points.

Lập Phương -- Cubic

Use cubic falloff, producing very soft points. Useful when points are very densely packed.

Độ Phân Giải -- Resolution

The dimensions of the texture holding the point data.

Nguồn Màu Sắc -- Color Source

Which attribute of the particle system or mesh is used to color the output.

Particle Color Sources
Tuổi Thọ Hạt -- Particle Age

Lifetime mapped as (0.0 - 1.0) intensity.

Tốc Độ Hạt -- Particle Speed

Particle speed (absolute magnitude of velocity) mapped as (0.0 - 1.0) intensity.

Vận Tốc Hạt -- Particle Velocity

XYZ velocity mapped to RGB colors.

Vertex Color Sources
Màu Điểm Đỉnh -- Vertex Color

Use a vertex color layer for coloring the point density texture.

Ghi chú

Vertex colors are defined per face corner. A single vertex can have as many different colors as faces it is part of. The actual color of the point density texture is averaged from all vertex corners.

Trọng Lượng Điểm Đỉnh -- Vertex Weight

Use weights from a vertex group as intensity values.

Pháp Tuyến Điểm Đỉnh -- Vertex Normals

Use object-space vertex normals as RGB values.

Đầu Ra -- Outputs

Màu Sắc -- Color

Đầu ra của màu chất liệu.

Tỷ Trọng -- Density

Density of volume.

Ví Dụ -- Examples
