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

Variants

Initialize

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.

Initialize the RayQuery object.

Proceed

Fields

result: Handle<Expression>

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.
