	)

overridevirtual

Registers a new procedural geometry type, which uses an intersection shader to determine hits for ray tracing.

Parameters

name	The name this procedural geometry type should be associated with. It must be unique within the ray tracing pipeline as it is used to match hit group records to hit groups.
intersectionShader	The intersection that should be used for procedural geometry of this type. The intersection shader must include the file <Atom/Features/RayTracing/RayTracingSrgs.azsli> and must use the struct `ProceduralGeometryIntersectionAttributes` to forward its hit parameters to ReportHit().
intersectionShaderName	The name of the intersection shader entry function within m_intersectionShader.
bindlessBufferIndex	A single 32-bit value which can be queried in the intersection shader with `GetBindlessBufferIndex()`. This value is in most cases obtained by calling GetBindlessReadIndex() on a RHI BufferView, such that it can be accessed with `Bindless::GetByteAddressBuffer(GetBindlessBufferIndex())` in the intersection shader.

Returns: A handle to the created type. If this handle is destroyed (by falling out of scope or calling .Free()), this procedural geometry type is also destroyed. This handle should be regarded as an opaque pointer, meaning that no member variables should be accessed or changed directly.
