HitObject.MakeHit

Description

Creates a HitObject representing a hit based on values explicitly passed as arguments, without tracing a ray. The primitive specified by AccelerationStructure, InstanceIndex, GeometryIndex, and PrimitiveIndex must exist. The shader table index is computed using the formula used with TraceRay. The computed index must reference a valid hit group record in the shader table. The Attributes parameter must either be an attribute struct, such as BuiltInTriangleIntersectionAttributes, or another HitObject to copy the attributes from.
