IOhannes m zmölnig 0e2ac2a91c X3D: simplistic attempt to avoid crashes due to nullptr access
Related: https://github.com/assimp/assimp/issues/4201

while the crashes go away, i'm not sure whether this is the correct fix.
also, afaict the X3D importer produces wrong results anyhow

IOhannes m zmölnig c8cdf3009e X3D: replace 'here' debugging printout by an assertion.
if mNodeElementCur is NULL, we get a crash anyhow...

IOhannes m zmölnig 23d7811276 X3D: consistent initialization with nullptr 2021-12-01 11:35:06 +01:00
IOhannes m zmölnig 836963428e Fix file-extension check for X3D-files
using the pre-existing and well-tested GetExtension() (which happens
to also normalize the extension), rather than attempting our own
buggy one...

Inho Lee 4a37aa2ef8 Interpolate euler rotations for quaternion animations
FBX uses euler rotation but assimp library's base type is
quaternion. When assimp convert FBX some animation information
can be lost.
This patch interpolates euler-angle rotations and insert
additional keyframes for the FBX format.

This turned up during fuzz testing. Corrupted data would make assimp write to random memory locations, leading to subsequent crashes.

RichardTea aaae3e3a10 size_t is 32bit on some platforms
Also assert if size_t is smaller than uint32_t (probably not necessary)
Note: 32bit builds will crash OOM if a really large model is loaded, as cannot allocate that much in total, let alone contiguously.

Fix overflowing allocations in MDLMaterialLoader
Some allocations might underallocate due to integer overflows. This
commit ensures that we are throwing an exception if the allocation size
does not fit in an unsigned int.
