The OpenGEX importer defined a few global std::string constants, only to convert them back to C strings on use. This commit defines them as C strings from the beginning.
strncmp() was used to compare these strings to other strings, but the length limit was set to string length, which made it equivalent to strcmp(), just slower. Fixed that as well.
The DXF importer defined a global std::string constant, only to convert it back to a C string on use.
This commit defines the constant as a C string right away, thus saving 340 B of code and data.
No effect on runtime speed/size. Slightly slower link time, but debugging experience improves by a million times.
- /Zi – Store debug information in a .pdb file, not directly in the DLL/EXE
- /DEBUG:FULL – generate debug information during link
- /PDBALTPATH:%_PDB% – do not store the file system path of the .pdb, just the filename and hash (no disclose paths on distribution)
- /OPT:REF /OPT:ICF – remove unreferenced functions and fold identical functions (this was enabled before, but requires explicit enabling if /DEBUG:FULL is specified)
The SIB importer, upon needing an empty aiString, did not create a new one but rather copied a predefined global empty string.
Since aiStrings contain large buffers, Assimp copied 1028 B of zeros instead of setting five bytes (at least when compiled with Visual C++). Since aiString is a user-defined type without a constexpr constructor, Visual C++ had to generate a thread-safe run-time initializer as well.
Now it’s just two instructions.
Maxon’s Melange SDK has been renamed Cineware SDK as of 21.004, and with it all namespaces and types. This commit
- makes CMake use contrib/Cineware instead of contrib/Melange;
- renames Assimp’s namespace melange to namespace cineware;
- removes useless functions and formatter references from class C4DImporter;
- removes duplicate conversion of cineware::String to aiString in the importer;
- updates comments accordingly;
- updates copyright info.
The regression was introduced to align 3DS export and import, but in fact it broke the transformation matrices on import. This commit reverts the relevant lines. Furthermore, matrix layout was double-checked with two other 3DS importers. Export was not considered.
Ogre and 3MF imports threw DeadlyExportErrors under some circumstances. Bad for people who assumed that they only needed to catch DeadlyImportErrors. Changed them to DeadlyImportErrors.
std::string s(""); s = ""; calls the copy constructor, which in turn calls strlen(), … assigning a default-constructed string generates fewer instructions and is therefore preferred.
With C++11 uniform initialization, you’d simply write s = { } instead.
“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.
