public class VkPhysicalDeviceRayTracingPropertiesNV
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Properties of the physical device for ray tracing.
Description

Due to the fact that the geometry, instance, and triangle counts are specified at acceleration structure creation as 32-bit values, maxGeometryCount, maxInstanceCount, and maxTriangleCount must not exceed 2³²-1.

If the VkPhysicalDeviceRayTracingPropertiesNV structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to GetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Limits specified by this structure must match those specified with the same name in VkPhysicalDeviceAccelerationStructurePropertiesKHR and VkPhysicalDeviceRayTracingPipelinePropertiesKHR.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_RAY_TRACING_PROPERTIES_NV
