Point Density Node

Point Density Node.

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

შენატანები

Vector

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

თვისებები (Properties)

Point Data

Where to get points from.

ნაწილაკოვანი სისტემა (Particle System)

Use each particle position from the specified particle system.

Object Vertices

Use each vertex position from the specified object.

ობიექტი (Object)

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

ნაწილაკოვანი სისტემა (Particle System)

Particle positions from this system will be used.

სივრცე (Space)

The coordinate system for mapping points.

სამყაროს სივრცე (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.

რადიუსი (Radius)

Size of the points.

ინტერპოლაცია (Interpolation)

Texel filtering type.

Closest:

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

წრფივი (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

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.

ნოტი

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.

გამონატანები

ფერი (Color)

Texture color output.

სიხშირე / სისქე (Density)

Density of volume.
