vkCmdSetViewportWithCount

To dynamically set the viewport count and viewports, call:

void vkCmdSetViewportWithCountEXT(
    VkCommandBuffer commandBuffer,
    uint32_t viewportCount,
    const VkViewport* pViewports);

• commandBuffer is the command buffer into which the command will be recorded.
• viewportCount specifies the viewport count.
• pViewports specifies the viewports to use for drawing.

This command sets the viewport count and viewports state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_VIEWPORT_WITH_COUNT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the corresponding VkPipelineViewportStateCreateInfo::viewportCount and pViewports values used to create the currently active pipeline.
