Description
This extension removes the Viewport
minDepth
and maxDepth
restrictions that the values must be between 0.0
and
1.0
, inclusive. It also removes the same restriction on
PipelineDepthStencilStateCreateInfo
minDepthBounds
and maxDepthBounds
. Finally it removes the
restriction on the depth
value in
ClearDepthStencilValue
.
New Enum Constants
Issues
1) How do Viewport
minDepth
and maxDepth
values outside of the 0.0
to 1.0
range interact with
Primitive Clipping?
RESOLVED: The behavior described in
Primitive Clipping
still applies. If depth clamping is disabled the depth values are still
clipped to 0 ≤ zc ≤ wc before the viewport transform. If depth clamping
is enabled the above equation is ignored and the depth values are
instead clamped to the Viewport
minDepth
and
maxDepth
values, which in the case of this extension can be outside of
the 0.0
to 1.0
range.
2) What happens if a resulting depth fragment is outside of the 0.0
to
1.0
range and the depth buffer is fixed-point rather than
floating-point?
RESOLVED: The supported range of a fixed-point depth buffer is 0.0
to 1.0
and depth fragments are clamped to this range.
