Return a copy

Downsample by averaging points together across axis. If multiple axes are specified, runs once per axis.

Toggle writing into the depth buffer Parameters ---------- flag : bool Whether depth writing should be enabled.

Called when this camera is changes its view. Also called when its associated with a viewbox.

Inject all objects that start with 'gl' from the source into the dest. source and dest can be dicts, modules or BaseGLProxy's.

Helper for assert_* ports

Return the intercepts of all lines defined in *lines1* as they intersect all lines in *lines2*. Arguments are of shape (..., 2, 2), w

Return projection of (a,b) onto (a,c) Arguments are point locations, not indexes.

Generate the vertices for straight lines between nodes. If it is a directed graph, it also generates the vertices which can be passed to

Rebuilds the shaders, and repositions the objects that are used internally by the ColorBarVisual

Add an Node to the scene for this ViewBox. This is a convenience method equivalent to `node.parent = viewbox.scene` Paramete

Merge this queue with another. Both queues will use a shared command list and either one can be used to fill or flush the shared queu

Compare an expected original array with the rendered result. Parameters ---------- orig_data Expected output result array. This w

Create the native widget if not already done so. If the widget is already created, this function does nothing.

Flush Parameters ---------- event : instance of Event The event.

Drop-in replacement for scipy.ndimage.gaussian_filter. (note: results are only approximately equal to the output of gaussian_filter)

Retrieve a graph layout Some graph layouts accept extra options. Please refer to their documentation for more information. Paramete

Returns the natural logarithm of the quaternion. (not tested)

Create orthographic projection matrix Parameters ---------- left : float Left coordinate of the field of view. right : float

Print current state with optional highlighting of what changed.

Configure this transform such that it maps points x0 => x1 Parameters ---------- x0 : array-like, shape (2, 2) or (2, 3)

Start the timer. A timeout event will be generated every *interval* seconds. If *interval* is None, then self.interval will be used.

Apply special mapping to edge cases (NaN and max/min clim).

Determine which mouse buttons are currently pressed based on the tkinter event state.

Internal method for resize.

Update border line to match new shape

Append data to the end. Parameters ---------- data : array_like An array, any object exposing the array interface

Get lowercase string representation of enum.

Get vertex normals Parameters ---------- indexed : str | None If None, return an (N, 3) array of normal vectors w

Restore a previous set of GL state parameters if available. If no previous GL state is available (see :py:meth:`.push_gl_state`), thi

Return array of pixel values in an attached buffer Parameters ---------- mode : str The buffer type to read. May

Emulate a double using two numbers of type float32.

Set a sub-region of the buffer (deferred operation). Parameters ---------- data : ndarray Data to be uploaded

Return a texture2D object for LUT after its value is set. Can be None.

Return a view on the collection using provided transform

mode: string - "raw" (speed: fastest, size: small, output: ugly, no dash, no thickness) - "agg" (speed: medium,

Called when a filter should be attached to a visual. Parameters ---------- visual : instance of Visual The visual

Ensure val is Nx(n_col), usually Nx3

Helper to check valid options

Return 1 if edges intersect completely (endpoints excluded)
