Details¶

class v_sim.Paths¶

An opaque structure to save a set of paths.

New in version 3.6.

classmethod new(translation)¶

Parameters:: translation ([float]) – the current box translation (cartesian).
Returns:: the newly create object v_sim.Paths, to be freed with v_sim.Paths.free().
Return type:: v_sim.Paths

Create a new v_sim.Paths object.

New in version 3.6.

classmethod parseFromXML(filename, paths)¶

Parameters:

filename (str) – a location on disk.
paths (v_sim.Paths) – a v_sim.Paths object.

Raises:

GLib.Error

Returns:

True on success.

Return type:

bool

Read an XML containing a description of paths. paths is newly created on success and should be freed with v_sim.Paths.free().

New in version 3.6.

addFromDiff(data, energy)¶

Parameters:

data (v_sim.DataDiff) – a v_sim.Data object with a geometry difference (see visu_geodiff_new()).
energy (float) – the current total energy, if any, otherwise use GObject.G_MAXFLOAT.

Returns:

True if new paths have been added.

Return type:

bool

This routine read the geometry difference hold in data and add a new step in the set of paths. If new paths are created, one should call v_sim.Paths.setTranslation() to be sure that all paths are moved inside the box.

New in version 3.6.

addNodeStep(time, nodeId, xyz, dxyz, energy)¶

Parameters:

time (int) – the flag that give the number of expansion to update.
nodeId (int) – the node to expand the path of.
xyz (float) – the current position of the path.
dxyz (float) – the variation in the path.
energy (float) – the energy of the system.

Returns:

True if a new path is started.

Return type:

bool

This routine expand the path for the given nodeId at position xyz of dxyz. The energy value will be used only if v_sim.Paths.setToolShade() is used with a non None v_sim.Shade. In that case the energy value will be used to colourise the provided path.

New in version 3.6.

constrainInBox(data)¶

Parameters:: data (v_sim.Data) – a v_sim.Data object.

Modify the corrdinates of the path nodes to contraint them in a box (when applying translations for instance).

New in version 3.6.

draw(pathWidth)¶

Parameters:: pathWidth (float) – the width for the drawn path

OpenGL calls to create the paths.

New in version 3.6.

empty()¶: Reinitialise internal values of a given self.

New in version 3.6.

exportXMLFile(filename)¶

Parameters:: filename (str) – a location on disk.
Raises:: GLib.Error
Returns:: True if no error.
Return type:: bool

Write an XML file with the description of the given self.

New in version 3.6.

free()¶: Free a set of paths.

New in version 3.6.

getLength()¶

Returns:: the number of steps.
Return type:: int

Get the number of steps stored in a v_sim.Paths.

New in version 3.6.

getToolShade()¶

Returns:: the v_sim.Shade used by the self.
Return type:: v_sim.Shade

The paths are drawn with a colourisation scheme.

New in version 3.6.

pinPositions(data)¶

Parameters:: data (v_sim.Data) – a v_sim.Data object.

Use the current positions of data to extend self.

New in version 3.6.

ref()¶

Returns:: itself.
Return type:: v_sim.Paths

Increase the ref counter.

New in version 3.7.

setToolShade(shade)¶

Parameters:: shade (v_sim.Shade) – a v_sim.Shade object.
Returns:: True is the scheme is changed.
Return type:: bool

Set the colourisation scheme for the path.

New in version 3.6.

setTranslation(cartCoord)¶

Parameters:: cartCoord (float) – three floats.

Change the translation of the path, stored in cartesian coordinates.

New in version 3.6.

unref()¶: Decrease the ref counter, free all memory if counter reachs zero.

New in version 3.7.
