        acceleration_structure: Handle<Expression>,
        descriptor: Handle<Expression>,
    },

Available on crate feature unstable-wgpu-27 only.

An operation that a RayQuery statement applies to its query operand.

Variants

Initialize

Initialize the RayQuery object.

Fields

acceleration_structure: Handle<Expression>

The acceleration structure within which this query should search for hits.

The expression must be an AccelerationStructure.

descriptor: Handle<Expression>

A struct of detailed parameters for the ray query.

This expression should have the struct type given in SpecialTypes::ray_desc. This is available in the WGSL front end as the RayDesc type.

Proceed

Start or continue the query given by the statement’s query operand.

After executing this statement, the result expression is a Bool scalar indicating whether there are more intersection candidates to consider.

Fields

result: Handle<Expression>

GenerateIntersection

Add a candidate generated intersection to be included in the determination of the closest hit for a ray query.

Fields

hit_t: Handle<Expression>

ConfirmIntersection

Confirm a triangle intersection to be included in the determination of the closest hit for a ray query.

Terminate
