Raycast Node

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.

目标几何体

Geometry that rays are tested against.

属性

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 was connected.

光线方向

射线长度

Maximum distance a ray can travel before being considered “no hit”.

映射

How attributes of the target mesh are mapped to the attribute values on the result geometry.

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 ray origin to the Hit Position.
