Nodo Distribuir en superficie

El nodo Distribuir en superficie distribuirá puntos o instancias a lo largo de la superficie de una malla. Proporcionará un control flexible sobre la forma en que los elementos serán ubicados mediante el uso de densidad, aleatorización y muestreo por disco de Poisson. Este nodo resultará útil para la distribución procedimental de objetos, tales como pasto, rocas o escombros sobre un terreno o cualquier otro tipo de superficie.

Entradas

Malla

The input surface geometry on which points or instances will be scattered.

Selección

Determines which faces or parts of the mesh are used for scattering. Unselected areas will not receive any scattered elements.

Método de densidad

Determinará la forma en que se controlará la cantidad de puntos distribuidos.

Densidad:

Uses a density field to define how many points are scattered per unit area.

Cantidad:

Uses a fixed number of total scattered points across the surface.

Método de distribución Densidad

Determines the pattern of scattered points when Density is used.

Aleatorio:

Distributes points randomly across the surface.

Disco de Poisson:

Distributes points evenly using a minimum separation distance.

Densidad Densidad

Controls the number of scattered points per unit area when using the Density method.

Cantidad Cantidad

The total number of points to scatter when using the Amount method.

Máscara de distribución

A mask that limits the areas where scattering occurs. Values closer to 1.0 allow scattering, while values near 0.0 exclude it.

Distancia mínima Disco de Poisson

Defines the minimum spacing between scattered points when using Poisson Disk distribution. Higher values result in more evenly spaced points but fewer total points.

Mantener superficie

Keeps the original surface geometry in the output, instead of outputting only the instances.

Distribuir sobre instancias

Enables scattering directly on existing instances rather than on a single mesh surface.

Semilla

Random seed value used to vary the distribution pattern of scattered points or instances.

Instanciado

Tipo de entrada

Defines how the instance geometry input is provided.

Bloque de datos:

Instances are created from an object or collection data-block.

Geometría:

Instances are created from input geometry provided to the node.

Tipo de instanciado Bloque de datos

When using Data-Block input, determines whether to instance an Object or a Collection.

Objeto / Colección Bloque de datos

The specific object or collection to instance when using Data-Block input mode.

Instancia Geometría

The geometry to instance when using Geometry input mode.

Visibles en vistas

Controls the percentage of scattered instances that are visible in the viewport.

Convertir instancias en reales

Converts all instances into real geometry, producing a single combined geometry output. This can be required for some subsequent geometry operations or modifiers.

Escoger instancia Bloque de datos Colección

When instancing from a collection, this option enables random or controlled selection of which child object to instance per scattered point.

Restablecer transformaciones

Resets the transform of instances before applying the scattering transform.

Semilla de instancias

Controls the randomization of instance selection and transforms per scattered element.

Transformación

Desplazamiento superficie

Moves instances along the element normal, offsetting them from the surface.

Alinear rotación

Aligns instance rotation to the orientation of the geometry element (e.g., normal direction).

Eje de alineación

Escala

Controls the uniform or per-axis scaling of instances.

Aleatorizar

Can be enabled through the boolean found in the panel header.

Desplazamiento

The maximum translation offset for each axis. Defines the random range for instance movement.

Rotación

The maximum rotation for each axis. Defines how much each instance can be rotated.

Ejes (aleatorizar escala)

Determines how scaling is applied.

Uniforme:

Applies a single random scale factor uniformly to all axes.

Ejes:

Applies an independent random scale factor to each axis.

Escala

The maximum scaling factor applied to each instance.

Aleatorizar inversión

Randomly flips instances along one or more axes, effectively mirroring them.

Semilla

An integer value that initializes the random number generator. Changing the seed produces a different random arrangement while keeping the same parameters.

Enmascarar

Imagen de máscara

An image used to control scattering density or placement via UV mapping.

Mapa UV

The UV map used to interpret the image mask for controlling distribution.

Salidas

Instancias

The resulting instances scattered across the surface, distributed according to the selected method and parameters.
