v3d.Ray#

class visu3d.Ray(**kwargs)[source]#

Bases: visu3d.array_dataclass.DataclassArray

6d vector with position and direction.

Note: The direction is not normalized by default.

pos#

Position

Type:

FloatArray[’*shape 3’]

dir#

Direction

Type:

FloatArray[’*shape 3’]

pos: FloatArray['*shape 3']#
dir: FloatArray['*shape 3']#
fig_config: plotly.TraceConfig = TraceConfig(     name=None,     num_samples=500, )#
property end: etils.enp.array_types.typing.FloatArray#

The extremity of the ray (ray.pos + ray.dir).

classmethod from_look_at(*, pos: etils.enp.array_types.typing.Array, target: etils.enp.array_types.typing.Array) → visu3d.dc_arrays.ray.Ray[source]#

Factory to create a look at Ray.

Alias of Ray(pos=pos, dir=target-from).

Parameters:

  • pos – Origin position

  • target – Target position

Returns:

The Ray.

scale_dir(scale: etils.enp.array_types.typing.FloatArray) → visu3d.dc_arrays.ray.Ray[source]#

Scale the dir.

norm(keepdims: bool = False) → etils.enp.array_types.typing.FloatArray[source]#

Returns the norm of the dir.

normalize() → visu3d.dc_arrays.ray.Ray[source]#

Normalize the directions.

mean(*, axis: None | Tuple[int, ...] | int = None) → visu3d.dc_arrays.ray.Ray[source]#

Returns the average ray.

look_at(target: etils.enp.array_types.typing.Array) → visu3d.dc_arrays.ray.Ray[source]#

Change the direction to point to the target point.

apply_transform(tr: visu3d.dc_arrays.transformation.Transform) → visu3d.dc_arrays.ray.Ray[source]#
make_traces() → list[plotly.basedatatypes.BaseTraceType][source]#

Construct the traces of the given object.
