}

TraceRay: a ray shot into an acceleration structure. The payload is the words of the program’s payload structure, which the programs the ray runs read and write; the caller leaves it as the ray’s last program did.

Fields

scene: ResourceId

The interface resource of the acceleration structure.

flags: u32

The ray’s flags (crate::ray_flags).

mask: u32

The instance inclusion mask: an instance is seen when it shares a bit with it.

hit_group_offset: u32

RayContributionToHitGroupIndex: added to the hit group index.

hit_group_stride: u32

MultiplierForGeometryContributionToHitGroupIndex: the geometry index is multiplied by it.

miss_index: u32

MissShaderIndex: which miss program runs if nothing is hit.

origin: [f32; 3]

The ray’s origin in world space.

t_min: f32

The nearest distance along the ray that counts as a hit.

direction: [f32; 3]

The ray’s direction in world space.

t_max: f32

The farthest distance along the ray that counts as a hit.

payload: &'a mut [u32]

The words of the payload structure.
