Point Density Node

Point Density Node.

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

Entradas

Vector

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

Propiedades

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.

Espacio

The coordinate system for mapping points.

World Space

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

Object Space

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

Radio

Size of the points.

Interpolación

Texel filtering type.

Más Cercano

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

Lineal

Interpolate linearly between texels, producing soft, round points.

Cúbico

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

Resolución

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.

Salidas

Color

Texture color output.

Density

Density of volume.
