solved Mesh rotation with pivot (beginner)

[yLacaute]

Hi,

I am trying to rotate a mesh with a custom pivot, using setPivotMatrix function. In the sample below, the pivot (red box)  "seems" to be in the right position, but the rotation done is not as expected (green and grey box should be superposed on the corner). I dont understand the setPivotMatrix

Why the pivot point (red box) is not inside the green box in this sample ?
I just would like something like :

   X
   X
  [X]  X  X  X

   Where [x] is the superposed part of the 2 meshes.

Thanks

I think samples in documentation should be updated, there are too complicated and some functions don't exist (like substract).

The great thing about the BJS documentation is that it is open source and anyone can submit to it. Please feel free to submit any simpler examples and explanation, contributions are always welcome.
