center : array_like
The location of the camera
normal_vector : array_like
The vector from the camera position to the center of the image plane
width : float or list of floats
width[0] and width[1] give the width and height of the image plane, and
width[2] gives the depth of the image plane (distance between the camera
and the center of the image plane).
The view angles thus become:
2 * arctan(0.5 * width[0] / width[2]) in horizontal direction
2 * arctan(0.5 * width[1] / width[2]) in vertical direction
(The following parameters are identical with the definitions in Camera class) :
resolution : int or list of ints
The number of pixels in each direction.
transfer_function : yt.visualization.volume_rendering.TransferFunction
The transfer function used to map values to colors in an image. If
not specified, defaults to a ProjectionTransferFunction.
north_vector : array_like, optional
The ‘up’ direction for the plane of rays. If not specific, calculated
automatically.
steady_north : bool, optional
Boolean to control whether to normalize the north_vector
by subtracting off the dot product of it and the normal
vector. Makes it easier to do rotations along a single
axis. If north_vector is specified, is switched to
True. Default: False
volume : yt.extensions.volume_rendering.AMRKDTree, optional
The volume to ray cast through. Can be specified for finer-grained
control, but otherwise will be automatically generated.
fields : list of fields, optional
This is the list of fields we want to volume render; defaults to
Density.
log_fields : list of bool, optional
Whether we should take the log of the fields before supplying them to
the volume rendering mechanism.
sub_samples : int, optional
The number of samples to take inside every cell per ray.
ds : ~yt.data_objects.api.Dataset
For now, this is a require parameter! But in the future it will become
optional. This is the dataset to volume render.
use_kd: bool, optional :
Specifies whether or not to use a kd-Tree framework for
the Homogenized Volume and ray-casting. Default to True.
max_level: int, optional :
Specifies the maximum level to be rendered. Also
specifies the maximum level used in the kd-Tree
construction. Defaults to None (all levels), and only
applies if use_kd=True.
no_ghost: bool, optional :
Optimization option. If True, homogenized bricks will
extrapolate out from grid instead of interpolating from
ghost zones that have to first be calculated. This can
lead to large speed improvements, but at a loss of
accuracy/smoothness in resulting image. The effects are
less notable when the transfer function is smooth and
broad. Default: True
data_source: data container, optional :
Optionally specify an arbitrary data source to the volume rendering.
All cells not included in the data source will be ignored during ray
casting. By default this will get set to ds.all_data().
