What did you do this week?
As decided last week, I added support for multiple animations at the same timestamp. But this didn't solve the animation problems of
I figured out that I was not applying the global transform of joints in the skinning matrix causing the joints to move to a new position. I referred to this answer by irradicator.
We had to invert the multiplication order (ie,
np.dot(skin_mat, vertex)instead of
np.dot(vertex, skin_mat)) for this model. We still need to figure out from where we get the multiplication order of the two.

I also tried to create a custom Interpolator that does all calculations required for vertex skinning. However, we couldn't get this working. I got a few suggestions from Mohamed in our meeting, I'll try to implement those.
Added tests for animations.
What is coming up next week?
- Adding more tests.
- Fixing the Interpolator.
- Order of multiplication in the skinning matrix.
Did you get stuck anywhere?
No, I didn't get stuck this week.
