The search for a matching importer had a few issues, see #3791. There were two different mechanisms to determine whether an importer accepts a specific file extension:
1. `aiImporterDesc::mFileExtensions`, which was forwarded to the UI via `BaseImporter::GetExtensionList()`.
2. `BaseImporter::CanRead()` when called with `checkSig == false`, which determines whether to actually use that importer.
Both were redundant and got out of sync repeatedly. I removed 2. completely and replaced it with 1., thereby syncing UI/import and shortening all `BaseImporter::CanRead()` implementations.
Further bugfixes:
- fixed glTF2 importer throwing exceptions when checking whether it can load a file
- removed `BaseImporter::SimpleExtensionCheck()` because it is no longer used and had a bug with case sensitivity
Since the `checkSig` parameter in `BaseImporter::CanRead()` is now useless, it can be removed completely. I’m not sure if this would break ABI compatiblity, so I’ll submit it with a later pull request.
“LazyDictBase::WriteObjects()” in the two glTF implementations is only used for export. Since it’s a virtual method, and many compilers have trouble removing unreferenced virtual methods, glTF export stuff is pulled into the binary even if compiling without exports.
This commit removes said virtual function if only compiling for import.
This removes 75 KiB of useless code when compiled with Visual Studio for x64.
CUBICSPLINE interpolation has tangent values with the animation data.
Current import don't care this interpolation type but it will help not
to fetch tangent values instead of animation data.
Note: Assimp cannot support interpolation types yet.
Primary changes are to include/assimp/metadata.h, adding in the aiMetadata GetAiType function,
adding the operator= to allow an aiMetadata type to be assigned, adding a check for the
AI_AIMETADATA type flag as it can't be trivially memcpy'd.
operator= is implemented with a by-value argument as then the copy is made by the copy
constructor and we can just swap everything out and let the destructor handle the mess.
Implemented parsing of the "extensions" flag on all glTF2 Nodes. Doesn't use the ReadValue
helper function on numbers as it did not seem to fill out the Nullable structure properly.
