vkCmdSetVertexInputEXT

To dynamically set the vertex input attribute and vertex input binding descriptions, call:

void vkCmdSetVertexInputEXT(
    VkCommandBuffer commandBuffer,
    uint32_t vertexBindingDescriptionCount,
    const VkVertexInputBindingDescription2EXT* pVertexBindingDescriptions,
    uint32_t vertexAttributeDescriptionCount,
    const VkVertexInputAttributeDescription2EXT* pVertexAttributeDescriptions);

• commandBuffer is the command buffer into which the command will be recorded.
• vertexBindingDescriptionCount is the number of vertex binding descriptions provided in pVertexBindingDescriptions.
• pVertexBindingDescriptions is a pointer to an array of VkVertexInputBindingDescription2EXT structures.
• vertexAttributeDescriptionCount is the number of vertex attribute descriptions provided in pVertexAttributeDescriptions.
• pVertexAttributeDescriptions is a pointer to an array of VkVertexInputAttributeDescription2EXT structures.

This command sets the vertex input attribute and vertex input binding descriptions state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_VERTEX_INPUT_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkGraphicsPipelineCreateInfo::pVertexInputState 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_BINDING_STRIDE dynamic state enabled, then vkCmdBindVertexBuffers2 can be used instead of vkCmdSetVertexInputEXT to dynamically set the stride.

The vertex attribute description for any location in the range [0,VkPhysicalDeviceLimits::maxVertexInputAttributes) not specified in the pVertexAttributeDescriptions array becomes undefined:.
