This extension provides additional orthogonally aligned "`discard
|
|
rectangles`" specified in framebuffer-space coordinates that restrict
|
|
rasterization of all points, lines and triangles.
|
|
|
|
From zero to an implementation-dependent limit (specified by
|
|
pname:maxDiscardRectangles) number of discard rectangles can be operational
|
|
at once.
|
|
When one or more discard rectangles are active, rasterized fragments can
|
|
either survive if the fragment is within any of the operational discard
|
|
rectangles (ename:VK_DISCARD_RECTANGLE_MODE_INCLUSIVE_EXT mode) or be
|
|
rejected if the fragment is within any of the operational discard rectangles
|
|
(ename:VK_DISCARD_RECTANGLE_MODE_EXCLUSIVE_EXT mode).
|
|
|
|
These discard rectangles operate orthogonally to the existing scissor test
|
|
functionality.
|
|
ifdef::VK_VERSION_1_1,VK_KHR_device_group[]
|
|
The discard rectangles can be different for each physical device in a device
|
|
group by specifying the device mask and setting discard rectangle dynamic
|
|
state.
