C Specification
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);
Parameters
-
commandBuffer
is the command buffer into which the command will be recorded. -
firstDiscardRectangle
is the index of the first discard rectangle whose state is updated by the command. -
discardRectangleCount
is the number of discard rectangles whose state are updated by the command. -
pDiscardRectangles
is a pointer to an array of VkRect2D structures specifying discard rectangles.
Description
The discard rectangle taken from element i of pDiscardRectangles
replace the current state for the discard rectangle at index
firstDiscardRectangle
+ i, for i in [0,
discardRectangleCount
).
This command sets the state for a given draw when the graphics pipeline is
created with VK_DYNAMIC_STATE_DISCARD_RECTANGLE_EXT
set in
VkPipelineDynamicStateCreateInfo::pDynamicStates
.
