The discard rectangles can be set dynamically with the command:
// Provided by VK_EXT_discard_rectangles void vkCmdSetDiscardRectangleEXT( VkCommandBuffer commandBuffer, uint32_t firstDiscardRectangle, uint32_t discardRectangleCount, const VkRect2D* pDiscardRectangles);
commandBufferis the command buffer into which the command will be recorded.
firstDiscardRectangleis the index of the first discard rectangle whose state is updated by the command.
discardRectangleCountis the number of discard rectangles whose state are updated by the command.
pDiscardRectanglesis a pointer to an array of VkRect2D structures specifying discard rectangles.
The discard rectangle taken from element i of
replace the current state for the discard rectangle at index
firstDiscardRectangle + i, for i in [0,
This command sets the state for a given draw when the graphics pipeline is
VK_DYNAMIC_STATE_DISCARD_RECTANGLE_EXT set in
