xmcd_projection.mesh_visualisation¶

class xmcd_projection.mesh_visualisation.MeshVisualizer(struct, projected_struct, projected_xmcd=None, struct_colors=None)¶

Object for visualising the xmcd projection

generate_view()¶: Generates the view data and sets the initial camera position.

get_blurred_image(sigma=4, desired_background=None)¶: Applies a Gaussian blur to the image to make it correspond to the actual measurements more

get_structs_center()¶

Gets the centre of the structure and the projected structure

update_colors(projected_xmcd, struct_colors)¶

Updates the colours of the xmcd and the structure. Repaints the view.

Parameters

projected_xmcd ((n,) array) – XMCD values of the projected structure faces.
struct_colors ((m,4) array) – Colurs of the structure faces.

update_xmcd_color()¶: Updates internally the colours of the xmcd and the background.

view_both(**kwargs)¶: View both the projection and the structure in the same render.

view_projection(**kwargs)¶: Removes the display of the structure and focuses only on the XMCD.

view_struct(**kwargs)¶: Removes the display of the projection and focuses only on the structure

class xmcd_projection.mesh_visualisation.NoProjectionVisualizer(struct, struct_colors=None)¶

Object for visualising only the structure. Useful when don’t have the xmcd information and just want to see the structure magnetisation.

generate_view()¶: Generates the view data and sets the initial camera position.

get_structs_center()¶

Gets the centre of the structure.

update_colors(struct_colors)¶

Updates the structure colours

class xmcd_projection.mesh_visualisation.PyQtVisualizer(dist=10000, background_color=0.5)¶

Bases: object

Parent class for the visualizers using PyQt5.

get_image_np(size=(1024, 1024))¶: Gets the image in the form plottable by matplotlib

save_render(filename, size=(1024, 1024))¶: Saves the render to filename with the givern resolution.

set_camera(ele=None, azi=None, dist=None, fov=None, center=None)¶

Sets the camera angle and position. Any kwag that is not passed is kept as is.

Parameters

ele (float, optional) – Elevation angle. Defaults to None.
azi (float, optional) – Azimuthal angle in deg. Defaults to None.
dist (float, optional) – Distance. Defaults to None.
fov (float, optional) – fov angle. Defaults to None.
center ((3,) array, optional) – Center of view location. Defaults to None.

show(**kwargs)¶: Show the visualization. All kwags are passed as camera parameters.
