public class VkAccelerationStructureSRTMotionInstanceNV
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying a single acceleration structure SRT motion instance for building into an acceleration structure geometry.
Description

The C language specification does not define the ordering of bit-fields, but in practice, this struct produces the correct layout with existing compilers. The intended bit pattern is for the following:
- instanceCustomIndex and mask occupy the same memory as if a single uint32_t was specified in their place
  - instanceCustomIndex occupies the 24 least significant bits of that memory
  - mask occupies the 8 most significant bits of that memory
- instanceShaderBindingTableRecordOffset and flags occupy the same memory as if a single uint32_t was specified in their place
  - instanceShaderBindingTableRecordOffset occupies the 24 least significant bits of that memory
  - flags occupies the 8 most significant bits of that memory
If a compiler produces code that diverges from that pattern, applications must employ another method to set values according to the correct bit pattern.

The transform for a SRT motion instance at a point in time is derived from component-wise linear interpolation of the two SRT transforms. That is, for a time in [0,1] the resulting transform is

transformT0 × (1 - time) + transformT1 × time

Valid Usage (Implicit)
- flags must be a valid combination of VkGeometryInstanceFlagBitsKHR values
