warp.mesh_query_ray_anyhit

warp.mesh_query_ray_anyhit(

id: uint64,

start: vec3f,

dir: vec3f,

max_t: float32,

root: int32,

) → bool

Kernel

Returns True immediately upon the first ray hit on the warp.Mesh with identifier id.

The root parameter can be obtained using the mesh_get_group_root() function when creating a grouped mesh. When root is a valid (>=0) value, the traversal will be confined to the subtree starting from the root. If root is -1 (default), traversal starts at the mesh’s global root.

param id:

The mesh identifier

param start:

The start point of the ray

param dir:

The ray direction (should be normalized)

param max_t:

The maximum distance along the ray to check for intersections

param root:

The root node index for grouped BVH queries, or -1 for global root (optional, default: -1)
