This commit adds two classes:
* ProgressTracker
* ProgressScope
The first is for users to implement, and to instantiate when they desire
to get informed about the overall progress.
The second is to be added to all functions that may take a considerable
amount of time, such that they can report back how far along they are.
These are much more convenient to use than the existing ProgressHandler.
ProgressScope is designed such that it only requires "local knowledge"
about upcoming and finished work. Scopes are nested and combined to
form the final global progress.
The active ProgressTracker is stored in a thread_local pointer.
This is a consicius decision since in assimp there is often no 'context'
passed through. The ProgressTracker may be needed anywhere, and it would
be tedious and a huge change to pass it through to every function.
Therefore, using a thread_local variable makes it accessible everywhere,
without a major interface change. Since assimmp is single-threaded,
but may be run in parallel on multiple threads, a thread_local is a
good trade-off, in my opinion.
This change only adds few uses of ProgressScope, to generally show how
it would be used. Also for our use cases these where the most pressing
places to add progress reporting, so this already covers loading from FBX
files pretty well.
This bug causes weights to duplicate, i.e. one bone will have several (equal) weights assigned to the same vertex - which then has the potential to cause even bigger problems when combined with `LimitBoneWeightsProcess`.
If I'm not mistaken. Because this is originally push_back(aniMeshVertex) instead of push_back(v).
And the fact that aniMeshVertex is just getting created and destroyed for nothing.
It need to be replaced with this then? A Clang-tidy syntax to create the same aniMeshVertex.
I found this in pull request #4527 I think it may need to be reviewed too.
