Inho Lee c2297e9199 Revert "FBXConverter : Fix timescales of FBX animations" 
The previous patch was made by misunderstanding about mTime.
It is not real time value, but time ticks.

This reverts commit b8bf1eac04.

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 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.

Prevent out-of-range memory writes by sparse accessors
 2021-11-26 09:02:17 +01:00
Jan Krassnigg 1a5d66714f Prevent out-of-range memory writes by sparse accessors 
This turned up during fuzz testing. Corrupted data would make assimp write to random memory locations, leading to subsequent crashes.
