Function Prototype

vkGetDeviceAccelerationStructureCompatibilityKHR

Check if a serialized acceleration structure is compatible with the current device

To check if a serialized acceleration structure is compatible with the current device call:

void vkGetDeviceAccelerationStructureCompatibilityKHR(
    VkDevice device,
    const VkAccelerationStructureVersionInfoKHR* pVersionInfo,
    VkAccelerationStructureCompatibilityKHR* pCompatibility);

device is the device to check the version against.
pVersionInfo is a pointer to a VkAccelerationStructureVersionInfoKHR structure specifying version information to check against the device.
pCompatibility is a pointer to a VkAccelerationStructureCompatibilityKHR value in which compatibility information is returned.

Valid Usage
