Point Density Node

The Point Density node is available in volume shaders, to render volumetric points for each particle or vertex of another object.

Entrades

Vector

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

Propietats

Point Data

Where to get points from.

Sistema de partícules

Use each particle position from the specified particle system.

Object Vertices

Use each vertex position from the specified object.

Objecte

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

Sistema de partícules

Particle positions from this system will be used.

Espai

The coordinate system for mapping points.

Espai de món:

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

Espai d’objectes:

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

Radi

Size of the points.

Interpolació

Texel filtering type.

El més pròxim:

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

Lineal:

Interpolate linearly between texels, producing soft, round points.

Cúbica:

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

Resolució

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

Color de vèrtex:

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.

Normals del vèrtex:

Use object-space vertex normals as RGB values.

Sortides

Color

Sortida de color de textura.

Densitat

Density of volume.
