class
hcipy.field.PolarGrid(coords, weights=None)¶ Bases:
hcipy.field.grid.GridA grid representing a two-dimensional Polar coordinate system.
Attributes Summary
The radial coordinate (dimension 0).
The angular coordinate (dimension 1).
Methods Summary
rotate(angle[, axis])Rotate the grid in-place.
scale(scale)Scale the grid in-place.
shift(shift)Shift the grid in-place.
shifted(shift)A shifted copy of this grid.
Attributes Documentation
-
r¶ The radial coordinate (dimension 0).
-
theta¶ The angular coordinate (dimension 1).
Methods Documentation
-
rotate(angle, axis=None)¶ Rotate the grid in-place.
- Parameters
- anglescalar
The angle in radians.
- axisndarray or None
The axis of rotation. For this (polar) grid, it is ignored.
- Returns
- Grid
Itself to allow for chaining these transformations.
-
scale(scale)¶ Scale the grid in-place.
- Parameters
- scalearray_like
The factor with which to scale the grid.
- Returns
- Grid
Itself to allow for chaining these transformations.
-
shift(shift)¶ Shift the grid in-place.
Caution
All structure in the coordinates will be destroyed.
- Parameters
- shiftarray_like
The amount with which to shift the grid.
- Returns
- Grid
Itself to allow for chaining these transformations.
-
shifted(shift)¶ A shifted copy of this grid.
Caution
The returned grid is a Cartesian grid.
- Parameters
- shiftarray_like
The amount with which to shift the grid.
- Returns
- Grid
The scaled grid.
