Nút Toán.

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.

Đầu Vào

Hình Học Mục Tiêu

Geometry that rays are tested against.

Thuộc Tính

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.

Vị trí Nguồn

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

Hướng Tia Xạ

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.

Chiều Dài của Tia Xạ

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

Tính Chất

Ánh Xạ

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

Nội Suy

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

Gần Nhất

Choose the value of the closest vertex without interpolating.

Đầu Ra

Va Đập Trúng

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

Vị Trí Điểm Va Đập

The location of the intersection point with the target mesh.

Pháp Tuyến của Điểm Va Đập

The surface Normal vector at the hit location.

Khoảng Cách Điểm Va Đập

The distance from the ray origin to the Hit Position.

Thuộc Tính

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