Raycast Node#

Nó Raycast.

The Raycast node intersects rays from one geometry onto another. The source geometry is defined by the context of the node that the Raycast node is connected to. Each ray computes hit points on the target mesh and outputs normals, distances and any surface attribute specified.


Target Geometry

Geometria que os raios são testados contra.


An optional field input evaluated on the Target Geometry that will be interpolated at the hit points. The resulting values are outputted with the Attribute output.

Source Position

The position from where to start each ray. By default, this is the same as if the Position Node was connected.

Ray Direction

Direction of each ray from the starting position. The field is evaluated on the geometry from the context of the field evaluation, not the Target Geometry.

Ray Length

Distância máxima que um raio pode viajar antes de ser considerado «no hit».



Como atributos da malha alvo são mapeados aos valores de atributos na geometria resultante.


Vertex and corner attributes are interpolated smoothly, with a bilinear function.

Choose the value of the closest vertex without interpolating.


Is Hit

Boolean output that is true for each ray which has hit the Target Geometry.

Hit Position

The location of the intersection point with the target mesh.

Hit Normal

The surface Normal vector at the hit location.

Hit Distance

The distance from the Source Position to the Hit Position. If the ray does not hit, the Ray Length is returned.


Interpolated values of the Attribute input sampled at the Hit Position.
