An array of planes used for culling ray tracing instances associated with the Renderers in a Scene.
To enable plane culling, use RayTracingInstanceCullingFlags.EnablePlaneCulling flag in RayTracingInstanceCullingConfig.flags.
A Renderer in the Scene is accepted to the acceleration structure if its AABB lies completely or partially on the positive side off all the Planes in the array.
