C Specification

To bind vertex buffers to a command buffer for use in subsequent draw commands, call:

void vkCmdBindVertexBuffers(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    firstBinding,
    uint32_t                                    bindingCount,
    const VkBuffer*                             pBuffers,
    const VkDeviceSize*                         pOffsets);

Parameters

  • commandBuffer is the command buffer into which the command is recorded.

  • firstBinding is the index of the first vertex input binding whose state is updated by the command.

  • bindingCount is the number of vertex input bindings whose state is updated by the command.

  • pBuffers is a pointer to an array of buffer handles.

  • pOffsets is a pointer to an array of buffer offsets.

Description

The values taken from elements i of pBuffers and pOffsets replace the current state for the vertex input binding firstBinding + i, for i in [0, bindingCount). The vertex input binding is updated to start at the offset indicated by pOffsets[i] from the start of the buffer pBuffers[i]. All vertex input attributes that use each of these bindings will use these updated addresses in their address calculations for subsequent draw commands.

Valid Usage
  • firstBinding must be less than VkPhysicalDeviceLimits::maxVertexInputBindings

  • The sum of firstBinding and bindingCount must be less than or equal to VkPhysicalDeviceLimits::maxVertexInputBindings

  • All elements of pOffsets must be less than the size of the corresponding element in pBuffers

  • All elements of pBuffers must have been created with the VK_BUFFER_USAGE_VERTEX_BUFFER_BIT flag

  • Each element of pBuffers that is non-sparse must be bound completely and contiguously to a single VkDeviceMemory object

Valid Usage (Implicit)
  • commandBuffer must be a valid VkCommandBuffer handle

  • pBuffers must be a pointer to an array of bindingCount valid VkBuffer handles

  • pOffsets must be a pointer to an array of bindingCount VkDeviceSize values

  • commandBuffer must be in the recording state

  • The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • bindingCount must be greater than 0

  • Both of commandBuffer, and the elements of pBuffers must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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