This extension adds support for an exclusive scissor test to Vulkan.
|
|
The exclusive scissor test behaves like the scissor test, except that the
|
|
exclusive scissor test fails for pixels inside the corresponding rectangle
|
|
and passes for pixels outside the rectangle.
|
|
If the same rectangle is used for both the scissor and exclusive scissor
|
|
tests, the exclusive scissor test will pass if and only if the scissor test
|
|
fails.

=== Issues
|
|
|
|
1) For the scissor test, the viewport state must be created with a matching
|
|
number of scissor and viewport rectangles.
|
|
Should we have the same requirement for exclusive scissors?
|
|
|
|
*RESOLVED*: For exclusive scissors, we relax this requirement and allow an
|
|
exclusive scissor rectangle count that is either zero or equal to the number
|
|
of viewport rectangles.
|
|
If you pass in an exclusive scissor count of zero, the exclusive scissor
|
|
test is treated as disabled.
