GridLayout
(cell_padding=0, cell_shape='rect', aspect_ratio=1.7777777777777777, dim=None)[source]¶ Bases:
fury.layout.Layout
Provide functionalities for laying out actors in a 2D grid fashion.
The GridLayout class lays the actors in a 2D structured grid aligned with the xyplane.

__init__
(cell_padding=0, cell_shape='rect', aspect_ratio=1.7777777777777777, dim=None)[source]¶  Parameters
cell_padding (2tuple of float or float (optional)) – Each grid cell will be padded according to (pad_x, pad_y) i.e. horizontally and vertically. Padding is evenly distributed on each side of the cell. If a single float is provided then both pad_x and pad_y will have the same value.
cell_shape ({'rect', 'square', 'diagonal'} (optional)) – Specifies the desired shape of every grid cell. ‘rect’ ensures the cells are the tightest. ‘square’ ensures the cells are as wide as high. ‘diagonal’ ensures the content of the cells can be rotated without colliding with content of the neighboring cells.
aspect_ratio (float (optional)) – Aspect ratio of the grid (width/height). Default: 16:9.
dim (tuple of int (optional)) – Dimension (nb_rows, nb_cols) of the grid. If provided, aspect_ratio will be ignored.

compute_positions
(actors)[source]¶ Compute the 3D coordinates of some actors.
The coordinates will lie on the xyplane and form a 2D grid.
 Parameters
actors (list of vtkProp3D objects) – Actors to be layout in a grid manner.
 Returns
The computed 3D coordinates of every actors.
 Return type
list of 3tuple

get_grid_cells_position
(shapes, aspect_ratio=1.7777777777777777, dim=None)[source]¶ Construct a XYgrid based on the cells content shape.
This function generates the coordinates of every grid cell. The width and height of every cell correspond to the largest width and the largest height respectively. The grid dimensions will automatically be adjusted to respect the given aspect ratio unless they are explicitly specified.
The grid follows a rowmajor order with the top left corner being at coordinates (0,0,0) and the bottom right corner being at coordinates (nb_cols*cell_width, nb_rows*cell_height, 0). Note that the X increases while the Y decreases.
 Parameters
shapes (list of tuple of int) – The shape (width, height) of every cell content.
aspect_ratio (float (optional)) – Aspect ratio of the grid (width/height). Default: 16:9.
dim (tuple of int (optional)) – Dimension (nb_rows, nb_cols) of the grid, if provided.
 Returns
3D coordinates of every grid cell.
 Return type
ndarray
