Point Density Node

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

Inputs

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

Point Data

Where to get points from.

Sistema de partículas: Use each particle position from the specified particle system.
Object Vertices: Use each vertex position from the specified object.

Objeto

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

Sistema de partículas

Particle positions from this system will be used.

Espaço

The coordinate system for mapping points.

Espaço do ambiente: Map each point exactly where the source particle or vertex is.
Espaço do objeto: Fit the points from the source particles/vertices inside the bounding box of the object with the point density texture.

Raio

Size of the points.

Interpolation

Texel filtering type.

Mais próximo: No interpolation, use nearest texel. Produces blocky looking points.
Linear: Interpolate linearly between texels, producing soft, round points.
Cubic: Use cubic falloff, producing very soft points. Useful when points are very densely packed.

Resolução

The dimensions of the texture holding the point data.

Color Source

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

Particle Color Sources

Particle Age: Lifetime mapped as (0.0 - 1.0) intensity.
Particle Speed: Particle speed (absolute magnitude of velocity) mapped as (0.0 - 1.0) intensity.
Particle Velocity: XYZ velocity mapped to RGB colors.

Vertex Color Sources

Vertex Color: Use a Color Attribute for coloring the point density texture.

Nota

Color Attributes 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.
Vertex Weight: Use weights from a vertex group as intensity values.
Vertex Normals: Use object-space vertex normals as RGB values.
