# VkPointClippingBehavior(3) Manual Page

## Name

VkPointClippingBehavior - Enum specifying the point clipping behavior

Loading… please wait.

## C Specification

Possible values of VkPhysicalDevicePointClippingProperties::`pointClippingBehavior`, specifying clipping behavior of a point primitive whose vertex lies outside the clip volume, are:

    // Provided by VK_VERSION_1_1
    typedef enum VkPointClippingBehavior {
        VK_POINT_CLIPPING_BEHAVIOR_ALL_CLIP_PLANES = 0,
        VK_POINT_CLIPPING_BEHAVIOR_USER_CLIP_PLANES_ONLY = 1,
      // Provided by VK_KHR_maintenance2
        VK_POINT_CLIPPING_BEHAVIOR_ALL_CLIP_PLANES_KHR = VK_POINT_CLIPPING_BEHAVIOR_ALL_CLIP_PLANES,
      // Provided by VK_KHR_maintenance2
        VK_POINT_CLIPPING_BEHAVIOR_USER_CLIP_PLANES_ONLY_KHR = VK_POINT_CLIPPING_BEHAVIOR_USER_CLIP_PLANES_ONLY,
    } VkPointClippingBehavior;

or the equivalent

    // Provided by VK_KHR_maintenance2
    typedef VkPointClippingBehavior VkPointClippingBehaviorKHR;

## Description

- `VK_POINT_CLIPPING_BEHAVIOR_ALL_CLIP_PLANES` specifies that the primitive is discarded if the vertex lies outside any clip plane, including the planes bounding the view volume.

- `VK_POINT_CLIPPING_BEHAVIOR_USER_CLIP_PLANES_ONLY` specifies that the primitive is discarded only if the vertex lies outside any user clip plane.
