Now I'm trying to play animation in game engine, reading texture atlas data exported in Animate.
I read the "animation.json" file to generate mesh for animation. Since "DecomposedMatrix" lacks skew data, I use the "Matrix3D" property.
The newest Animate version export only key frames instead of all frames, so I need to make interpolation between two key frames.
But when I using normal interpolation algorithm between two "Matrix3D" from two key frames, the animation seems different with origonal animation. When I use texture atlas data exported from older version of Animate, which exports all frames, it works well.
So, what is the right way to make interpolation for matrix? Do I need to decompose the matrix into position, rotation, scale and skew data and make interpolation seperately?
