Node Point Density.

Le Node Point Density est utilisé pour ajouter des points volumétriques pour chaque particule ou sommet d’un autre objet.

Entrées

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

Propriétés

Point Data

Where to get points from.

Particle System
Utiliser chaque position de particule du système de particules spécifié.
Object Vertices
Utiliser chaque position de sommet de l’objet spécifié.
Object
Quels sommets d’objet ou quel système de particules sera(seront) utilisé(s).
Particle System
Les positions de ce système seront utilisées.
Space

The coordinate system for mapping points.

World Space
Map each point exactly where the source particle/vertex is.
Object Space
Fit the points from the source particles/vertices inside the bounding box of the object with the point density texture.
Radius
Size of the points.
Interpolation

Texel filtering type.

Closest
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.
Resolution
Les dimensions de la texture contenant les données de points.
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 vertex color layer for coloring the point density texture.

Note

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.

Vertex Weight
Utiliser les poids d’un groupe de sommets comme valeurs d’intensité.
Vertex Normals
Use object-space vertex normals as RGB values.

Sorties

Color
Sortie de couleur de texture.
Density
Densité de volume.
