Rotations
=========
Note: these have caused many subtle bugs in the past.
Be careful while updating these methods and while using them in clever ways.
See MuJoCo documentation here: http://mujoco.org/book/modeling.html#COrientation
Conventions
-----------
- All functions accept batches as well as individual rotations
- All rotation conventions match respective MuJoCo defaults
- All angles are in radians
- Matricies follow LR convention
- Euler Angles are all relative with 'xyz' axes ordering
- See specific representation for more information
Representations
---------------
Euler
There are many euler angle frames -- here we will strive to use the default
in MuJoCo, which is eulerseq='xyz'.
This frame is a relative rotating frame, about x, y, and z axes in order.
Relative rotating means that after we rotate about x, then we use the
new (rotated) y, and the same for z.
Quaternions
These are defined in terms of rotation (angle) about a unit vector (x, y, z)
We use the following <q0, q1, q2, q3> convention:
q0 = cos(angle / 2)
q1 = sin(angle / 2) * x
q2 = sin(angle / 2) * y
q3 = sin(angle / 2) * z
This is also sometimes called qw, qx, qy, qz.
Note that quaternions are ambiguous, because we can represent a rotation by
angle about vector <x, y, z> and -angle about vector <-x, -y, -z>.
To choose between these, we pick "first nonzero positive", where we
make the first nonzero element of the quaternion positive.
This can result in mismatches if you're converting an quaternion that is not
"first nonzero positive" to a different representation and back.
Axis Angle
(Not currently implemented)
These are very straightforward. Rotation is angle about a unit vector.
XY Axes
(Not currently implemented)
We are given x axis and y axis, and z axis is cross product of x and y.
Z Axis
This is NOT RECOMMENDED. Defines a unit vector for the Z axis,
but rotation about this axis is not well defined.
Instead pick a fixed reference direction for another axis (e.g. X)
and calculate the other (e.g. Y = Z cross-product X),
then use XY Axes rotation instead.
SO3
(Not currently implemented)
While not supported by MuJoCo, this representation has a lot of nice features.
We expect to add support for these in the future.
TODO / Missing
--------------
- Rotation integration or derivatives (e.g. velocity conversions)
- More representations (SO3, etc)
- Random sampling (e.g. sample uniform random rotation)
- Performance benchmarks/measurements
- (Maybe) define everything as to/from matricies, for simplicity
