It's four pointers, twice as much as what would be acceptable. Not sure
why this happened, maybe because all those cases used an ArrayView
before and so I just changed the type without considering the difference
in its size?
Unfortunately this change also means a bump in the plugin interface
string, thus all scene converter plugins have to be updated as well.
Makes a lot of use cases significantly simpler -- apart from the trivial
"convert an OBJ to a glTF" scenario, many processing steps are about
passing most data through but only doing a pass on meshes, or images, or
materials. And this simplifies that use case quite a lot.
This is only "driver" code, with no new interfaces for the plugins. For
them it still looks like all data, their names and related metadata were
added one by one.
Also, a suprisingly large amount of code for this feature.
This happened because I made an early implementation of the batch
AbstractSceneConverter APIs, stashed it away, then implemented image
flags and then continued working on the stash, unaware that it's
outdated.
And properly test the behavior as well. While it's rare that a batch
and immediate conversions would be mixed on a single converter instance,
if it happens by accident it should not lead to unexpected internal
state.
Initially I thought there was no reason for this to fail, but then
realized AnySceneConverter would need it. And also any other plugin
relying on something external that might fail during initialization --
there's no other moment after plugin instantiation where it could
signalize a failure, and deferring that to the first add() call,
whichever would it be, is really not a sane idea.
Wasn't really possible to split this into multiple commits, so here's
the whole thing including delegation from and to the single-mesh APIs.
What's not done here and postponed for later is:
- an ability to feed the whole importer to it, filtering away data that
aren't supported by the converter
- corresponding changes in AbstractImageConverter, where it would now
primarily accept ImageData to future-proof for arbitrary extra
key/value data
This is what commit ca722eac6e should
have been.
Sorry for breaking a non-deprecated MSVC build once again. The reason it
"appeared to work" for me was that on deprecated builds, Manager.h
includes Manager.hpp for backwards compatibility. On non-deprecated it
doesn't and MSVC ends up dying on a linker error. But the problem was
not related to extern templates, the problem was that there was a
compiler-specific ifdef in the cpp file which exported the class for all
compilers but MSVC, somehow. And so when I removed extern template from
the header, it still worked everywhere, except MSVC and except a
non-deprecated build.
Hey, do you also remember the times where people were excited to upgrade
from Clang 3.6 to 3.7, GCC 4.7 to 4.8 or Firefox 1.1 to Firefox 1.5? Not
Clang 12 to 14, GCC 10 to 13 or Chrome 102 to 126.
Consistently with changes done to Utility::Path, this enforces proper
error handling on user side. Originally I didn't want to do this and
instead wanted to have a special Array instance devoted for an error
state, but that still would allow the error state be errorneously
treated as a successful but empty array.
For file opening there's no longer an unatomic pair of exists() +
read(), but since Path::read() now returns an Optional, it means we can
reliably distinguish between empty files and failures.
While at it, also added TODOs for removal of the StringStl.h header
that's needed in various places for compatibility with APIs still using
STL strings.
It was a clever harmless trick. Well, it was way more harmless than it
was clever, but even then it caused UBSan to complain. And that's Not A
Good Thing for various reasons, so let's just comply.
The main bad effect of this change is a *slightly* larger list of
exported symbols but until we actually get rid of the major bloats like
<iostream>, <string> and the like, this is not going to have any
measurable impact.
It should be input first, output second, like with all other APIs. I
remember I was trying something else here, but that didn't really make
sense in the end. Also took that opportunity to get rid of one
std::string.
The original signature is a deprecated alias to the new one and will be
removed in a future release.
There will be Flag::FlipY for images at some point, enabled by default
for compatibility with existing GL code, and so it makes sense to start
discouraging setFlags() as early as possible to avoid people resetting
the default by accident.
Also update the imageconverter, sceneconverter and shaderconverter utils
to use these instead of setFlags().
