pytransform3d.transformations.random_screw_axis(rng=Generator(PCG64) at 0x7FA768DBB040)[source]

Generate random screw axis.

Each component of v will be sampled from a standard normal distribution \mathcal{N}(\mu=0, \sigma=1). Components of \omega will be sampled from a standard normal distribution and normalized.

Parameters:
rngnp.random.Generator, optional (default: random seed 0)

Random number generator

Returns:
screw_axisarray, shape (6,)

Screw axis described by 6 values (omega_1, omega_2, omega_3, v_1, v_2, v_3), where the first 3 components are related to rotation and the last 3 components are related to translation.
