We can not do it from builder, since builder will pull set scenes.
|
|
view_layer_object_copy test was broken.
This is a quick fix for now, can be optimized further later.
|
|
This statement is only relevant in 2.8, but causes confusion in master.
I kept the 'default' label to prevent compiler warnings about unhandled
cases. The break is needed because there should be at least one statement
after 'default'.

This will reduce amount of needless auto-override checks, at least when
not touching anything related to overriding IDs...
|
|
Saves us from extra checks for NULL pointers when using datablocks for read.
|
|
Was caused by two things from the past:
- Tagging would set id->recalc to COW update flag.
This one is to be ignored.
- Particle tagging will use psys recalc flags on id->recalc,
but we only need to use flags from particles. Otherwise
it will be some collisions in bit masks.

The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

The depsgraph now contains all the state needed to evaluate it.

This was only used for viewport rendering, where we can just pass the engine
type directly. There is no technical reason why we can't draw the same depsgrpah
with different render engines.
It also led to some weird things like requiring a render engine for snapping
and raycast API functions.

Scene, view layer and mode are now set in the constructor and never changed.
Time is updated on frame changes to indicate which frame is being or has been
evaluated last.
This is a step towards making EvaluationContext obsolete.

Unless there is an external action from an user, there should not
be need in re-copying original datablock to a copied one.
This brings performance up from 5fps to 11fps with Spring runcycle
(performance in master is 14fps).
|
|
Quite straightforward implementation, allows us to remove all the cherry-picking
update of specified scene/view layer/collection fields. Makes it possible to use
generic function to update scene.
The tricky part is that we need to know view layer pointer before the whole
evaluation starts. So we actually expand scene at initialization of evaluation.
context. This is still a bit of an exceptional case, but at least we still avoid
dangerous cherry-picking update.
|
|
Currently unused, but will become handy to check whether ID needs
to have COW update to be run.
|
|
For the performance we convert object bases list to an array
during view layer evaluation. This makes it possible to have
very cheap index-based base lookup.
The goal of this change is to get rid of base used for function
binding, and avoid scene datablock expansion at the depsgraph
construction time.
|
|
Makes it a bit slower to evaluate single view layer, but this is does not
happen often, and overall number of layers is not very high.
|
|
Use single function to evaluate all the collections for the given view layer.
This way we avoid need to get scene ID sub-data. Similar to pchan index, this
allows us to avoid build-time scene expansion, which also simplifies update of
the scene datablock.
Well, sort of. There is still work to be done to get rid of build-time scene
datablock expansion, which includes:
- Need to pass view layer by index.
Annoying part would be to get actual view layer for that index. In practice
doing list lookup might not be such a bad idea, since such lookup will not
happen very often, and it is unlikely to have more than handful of view
layer anyway.
Other idea could be to use view layer from evaluation context.
Or maybe from depsgraph, which is supposed to be in the context. Can have
some assert statements to make sure everything is good.
- Need to get id of base binding for flags flush.
We can replace that with index-based lookup from an array created by view
layer evaluation.

This is similar to previous fix for missing ID nodes, just the original
fix missed this part of change because it looked like it is already
happening.
|
|
Makes it more reliable to see what was updating last when
crash happens.
|
|
With index-based pchan evaluation we don't need to go into
a mess of expanding armature at relation construction time.
|
|
|
|
This caused too many problems syncing object modes
with multiple objects/windows/workspaces, see: D3130 for details.

Was missing ID looper for pchan constraint.

The issue was caused by component tag forcing CoW component to be run,
without actually flushing changes down the road from the CoW operation.
In a way, this is what we want: we do want CoW to run on changes, but
we don't want tiny change forcing full datablock update.
This commit makes it so order of updates is all correct, but the bigger
issue is still open: what parts of datablock CoW should be updating?
Now it's possible to open spring file and play around.

This code should be replaced with evaluation-time ID block expansion,
but before that it will be helpful to get old design to work again.

The cache was getting reset always, due to special case of flag being 0.
Bug introduced by: 44cd24a9cee9ffb14b5d26a622f

This was fixed in 2.8 branch but not in master.
|
|
|

This is a part of copy-on-write sanitization, to avoid all the checks
which were attempting to keep sub-data pointers intact.
Point is: ID pointers never change for CoW datablocks, but nested
data pointers might change when updating existing copy.
Solution: Only bind ID data pointers and index of sub-data.
This will make CoW datablock 7update function was easier in 2.8.
In master we were only using pose channel pointers in callbacks,
this is exactly what this commit addresses. A linear lookup array
is created on pose evaluation init and is thrown away afterwards.
One thing we might consider doing is to keep indexed array of
poses, similar to chanhash.

Fix for T54437: Sequencer preview uses last updated scene
The fix started in master, moving EvaluationContext initialization
before we leave `deg_evaluate_on_refresh()`.
Upon merging master we can fix the actual issue which was to set
the EvaluationContext depsgraph even if the depsgraph was already updated.
|
|
This is required to T54437 (sequencer preview uses last updated scene).
Although the fix itself needs to be in 2.8, for the 2.8 specific
initialization code.
|
|
Use more generic id->recalc flag.
Also sanitize flag flush from settings to particle system.
Need to do such flush before triggering point cache reset, since
point cache reset will do some logic based on what flags are set.
This will solve crash caused by threaded update which will set
some bitflags while point cache reset is in progress.
|
|
Tagging based on components might not be granular enough.
For example, for particles we would want to know what part
of particles was changed exactly. For the flushing we wouldn't
worry too much, because we will want less granular updates
there anyway.
|
|
|
|
Timing is printed to the console when running with --debug-depsgraph-time.
|
|
Rather a mistake since previous merge.

Empties were missing Parameters component.
