DebugShaderInputs struct contains existing the parameters:
sample
primitive
and a new parameter
view
Default constructor for DebugShaderInputs sets the parameters to NoPreference (~0U).
New 'Exploded' visualisation mode in BufferViewer with new exploder controls
hidden when not in 'Exploded' mode.
Change 'solidShading' and 'solidShadeMode' to 'visualisation' and
'visualisationMode'.
Hide the 'highlightVerts' widget when using 'Exploded' vis for both
real-estate and practical implementation reasons.
This is supported by OpenGL, and on Vulkan with
VK_EXT_primitive_topology_list_restart. On Vulkan, all drivers are
known to support this even without
VK_EXT_primitive_topology_list_restart. On D3D, primitive restart is
only supported for strip topologies.
Previously, RenderDoc specifically disabled primitive restart for
non-strip topologies. In this change, that is no longer done. If the
app enables primitive restart, so will RenderDoc behave accordingly. It
would be the responsibility of the app to avoid primitive restart if the
API doesn't allow it.
* Most of the main entry points that can fail with relevant reasons now has a
way of specifying a message to return with it. This message can be displayed
to the user to give more information or context about an error.
* This is a stupid requirement as the quad overdraw shader doesn't use any
interpolators, but the D3D12 runtime complains and refuses to create a PSO
unless the PS has a matching signature. This works as long as the position was
the first output from the previous stage, but if it isn't the PSO fails to
create.
* To fix this, we take the existing shader and patch it by grafting the output
signature from the last stage over onto the input signature, and patching up
where the position is.
* There's not a good accepted terminology for this kind of event, and for
historical reasons 'drawcall' has been the accepted term, even though
that can be quite confusing when a dispatch or a copy is a 'drawcall'.
* This is particularly highlighted by the event browser filters where
$draw() includes draws and dispatches, but $dispatch() only includes
dispatches, it's hard to intuitively understand why $draw() matches all
of these calls.
* As a result we've defined the term 'action' to cover these types of
events in the same way that we defined 'event' in the first place to
mean a single atomic API call.
* When displaying mip 0 of a texture at less than 100% zoom we linear sampling,
but we don't want to linear sample across slices. Adding a half pixel offset
in z ensures we sample precisely on the slice itself.
* These map more naturally to python tuples and are easier to wrap in and out.
* We also tidy up the FloatVecVal etc and standardise the members of
ShaderValue.
