snudda.place.rotation

class snudda.place.rotation.SnuddaRotate(config_file=None)

Rotation object.

Constructor

Parameters:

config_file – Path to network config file

get_rotations(volume_name, neuron_type, neuron_positions, rng)

Gets rotations for neuron_type in volumne name at neuron_positions

static load_rotation_field(rotation_field_file, volume_name)

Loads rotation field for volumne_name from rotation_field_file

static rand_rotation_matrix(deflection=1.0, rand_nums=None, rng=None)

Creates a random rotation matrix.

deflection: the magnitude of the rotation. For 0, no rotation; for 1, competely random rotation. Small deflection => small perturbation. rand_nums: 3 random numbers in the range [0, 1]. If None, they will be auto-generated.

static random_z_rotate(rng)

Helper method, rotate around z-axis (of SWC coordinates)

static rotation_matrix_from_vectors(vec1, vec2)

Creates a rotation matrix to rotate vec1 into vec2.
