Provided that we are using perspective projection, our ray goes from the camera’s “eye” to the just-found point. In some cases, Open3D may use an orthogonal camera, but this is out of this post’s scope. The VoxelPicking::Unproject method on the code I linked above is an implementation of this procedure. From Ray to Voxel.

For AABBs this is quite easy to determine due to the fact that they're aligned to the scene's axes: we check for each axis if the two object' edges on that axis overlap. So we check if the horizontal edges overlap, and if the vertical edges overlap of both objects. If both the horizontal and vertical edges overlap we have a collision.

It simulates a camera where we can control all its parameters, intrinsic and extrinsic to get a better understanding how each component in the camera projection. Assuming your matrix is an extrinsic parameter matrix of the kind described in the Wikipedia article, it is a mapping from world coordinates to camera coordinates. So, to find the position C of the camera, we solve. \begin {align*}0 &= RC + T\\ C &= -R^T T \approx (-2.604, 2.072, -0.427).\end {align*} The orientation of the camera is given.
