Loading… please wait.

## C Specification

Possible values of `pCompatibility` returned by vkGetDeviceAccelerationStructureCompatibilityKHR are:

    // Provided by VK_KHR_acceleration_structure
    typedef enum VkAccelerationStructureCompatibilityKHR {
        VK_ACCELERATION_STRUCTURE_COMPATIBILITY_COMPATIBLE_KHR = 0,
        VK_ACCELERATION_STRUCTURE_COMPATIBILITY_INCOMPATIBLE_KHR = 1,
    } VkAccelerationStructureCompatibilityKHR;

## Description

- `VK_ACCELERATION_STRUCTURE_COMPATIBILITY_COMPATIBLE_KHR` if the `pVersionData` version acceleration structure is compatible with `device`.

- `VK_ACCELERATION_STRUCTURE_COMPATIBILITY_INCOMPATIBLE_KHR` if the `pVersionData` version acceleration structure is not compatible with `device`.
