vkGetDeviceMicromapCompatibilityEXT(3)

C Specification

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

// Provided by VK_EXT_opacity_micromap
void vkGetDeviceMicromapCompatibilityEXT(
    VkDevice                                    device,
    const VkMicromapVersionInfoEXT*             pVersionInfo,
    VkAccelerationStructureCompatibilityKHR*    pCompatibility);

Parameters

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