vkCmdBindVertexBuffers2

Alternatively, to bind vertex buffers, along with their sizes and strides, to a command buffer for use in subsequent drawing commands, call:

void vkCmdBindVertexBuffers2EXT(
    VkCommandBuffer commandBuffer,
    uint32_t firstBinding,
    uint32_t bindingCount,
    const VkBuffer* pBuffers,
    const VkDeviceSize* pOffsets,
    const VkDeviceSize* pSizes,
    const VkDeviceSize* pStrides);

• 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.
• pSizes is NULL or a pointer to an array of the size in bytes of vertex data bound from pBuffers.
• pStrides is NULL or a pointer to an array of buffer strides.

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]. If pSizes is not NULL then pSizes[i] specifies the bound size of the vertex buffer starting from the corresponding elements of pBuffers[i] plus pOffsets[i]. If pSizes[i] is VK_WHOLE_SIZE then the bound size is from pBuffers[i] plus pOffsets[i] to the end 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 drawing commands. If the nullDescriptor feature is enabled, elements of pBuffers can be VK_NULL_HANDLE, and can be used by the vertex shader. If a vertex input attribute is bound to a vertex input binding that is VK_NULL_HANDLE, the values taken from memory are considered to be zero, and missing G, B, or A components are filled with (0,0,1).

This command also dynamically sets the byte strides between consecutive elements within buffer pBuffers[i] to the corresponding pStrides[i] value when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_VERTEX_INPUT_BINDING_STRIDE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, strides are specified by the VkVertexInputBindingDescription::stride values used to create the currently active pipeline.

If drawing using shader objects or if the bound pipeline state object was also created with the VK_DYNAMIC_STATE_VERTEX_INPUT_EXT dynamic state enabled then vkCmdSetVertexInputEXT can be used instead of vkCmdBindVertexBuffers2 to set the stride.
