# vkCmdSetDepthBounds(3) Manual Page

## Name

vkCmdSetDepthBounds - Set the depth bounds test values for a command buffer

## C Specification

The depth bounds test conditionally disables coverage of a sample based on the outcome of a comparison between the value za in the depth attachment at location (xf,yf) (for the appropriate sample) and a range of values. The test is enabled or disabled by the `depthBoundsTestEnable` member of VkPipelineDepthStencilStateCreateInfo: If the pipeline state object is created without the `VK_DYNAMIC_STATE_DEPTH_BOUNDS` dynamic state enabled then the range of values used in the depth bounds test are defined by the `minDepthBounds` and `maxDepthBounds` members of the VkPipelineDepthStencilStateCreateInfo structure. Otherwise, to dynamically set the depth bounds range values call:

    void vkCmdSetDepthBounds(
        VkCommandBuffer                             commandBuffer,
        float                                       minDepthBounds,
        float                                       maxDepthBounds);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `minDepthBounds` is the lower bound of the range of depth values used in the depth bounds test.

- `maxDepthBounds` is the upper bound of the range.

## Description

Valid Usage

- Unless the `https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_EXT_depth_range_unrestricted` extension is enabled `minDepthBounds` must be between `0.0` and `1.0`, inclusive

- Unless the `https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_EXT_depth_range_unrestricted` extension is enabled `maxDepthBounds` must be between `0.0` and `1.0`, inclusive

Valid Usage (Implicit)

- `commandBuffer` must be a valid VkCommandBuffer handle

- `commandBuffer` must be in the recording state

- The `VkCommandPool` that `commandBuffer` was allocated from must support graphics operations

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

- Host access to the `VkCommandPool` that `commandBuffer` was allocated from must be externally synchronized

Command Properties
