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.
* We need to calculate the fixed data length properly even when there is no
repeated data, so that pagination doesn't kick in on the data that is needed
for the fixed region.
* We can't debug geometry shaders but we can scroll to them, as long as we have
the primitive. We can't differentiate instances currently without passing that
data through from the VS (and through tessellation, if it exists).
* This also disables the debug and goto buttons for printfs from shader stages
that don't support those operations.
* Unifying these views means that constant buffers have all the same
reformatting and it avoids having multiple paths for what is now effectively
the same control (a buffer can either have fixed data, repeating data, or
both)
* GL and Vulkan allow buffers to have fixed variables before a trailing AoS
unbounded array. These fixed variables can't be easily displayed in a table
and previously we skipped them. Now we display these in a tree format.
* We also support formats which don't have an unbounded array at all and display
these just with the tree. This will allow the BufferViewer to subsume the
capabilities of the ConstantBufferPreviewer (though it needs to handle opaque
non-buffer-backed variables, and slot-following).
* This allows the calling code to pass a hint of what packing is known or likely
to be used, meaning less generated manual offsetting/padding when the implicit
rules cover it.
* Instead of having a global tight/non-tight we now let the format string
specify the packing rules (defaulting to scalar - i.e. tight packing as
before), and use the resulting properties to calculate packing.
- Add a new combo box and button to camera settings for mesh viewer
- Add a new dialog window for custom axis mappings
- Implement the axis mappings in gl driver (other drivers to come)
* When using VS In we want to ignore the W component, but that already happens
explicitly for vulkan/GL in the shader. Mirror that same solution to D3D
instead of trying to force a 3-component format which may not be supported
(e.g. on AMD R16G16B16_*)
* On GL you can specify a vertex attribute that's stored as int but gets
converted to float with glVertexAttribFormat instead of glVertexAttribIFormat.
However if the shader accepts an int this is invalid and the value is
undefined - we emulate this as the float bits being read as int directly, but
that's not guaranteed behaviour.
* Normally we don't emulate this kind of mis-cast behaviour and just display the
type of data passed to the shader, but in this case GL lets you specify three
types (stored as int, cast to float, read as int) so our normal behaviour of
just showing the input can be more misleading than normal.
* 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.
