SetViewPort()

void Spices::Renderer::RenderBehaveBuilder::SetViewPort

(

const VkCommandBuffer &

cmdBuffer = VK_NULL_HANDLE

)

const

DynamicState Set Viewport and Scissor.

Parameters

[in]

cmdBuffer

VkCommandBuffer

Use Negative Viewport height filp here to handle axis difference. Remember enable device extension (VK_KHR_MAINTENANCE1)

Though we draw world to viewport but not surface, Set Correct viewport here is necessary.

Instance a VkRect2D.

Set VkViewport with viewport slate.

Set VkRect2D.
