Class Details¶

class v_sim.GlExtNodes(**kwargs)¶

Bases:: v_sim.GlExt, v_sim.NodeArrayRenderer
Abstract:: No
Structure:: v_sim.GlExtNodesClass

An opaque structure.

New in version 3.7.

classmethod new()¶

Returns:: a pointer to the v_sim.GlExt it created or None otherwise.
Return type:: v_sim.GlExtNodes

Creates a new v_sim.GlExt to draw a set of nodes. It can be used also for picking, see v_sim.GlExtNodes.getSelection().

New in version 3.7.

getSelection(x, y)¶

Parameters:

x (int) – a window coordinate;
y (int) – a window coordinate.

Returns:

-1 if no node found, or its id.

Return type:

int

Get the id of a v_sim.Node on top of the z-buffer.

New in version 3.7.

getSelectionByRegion(x1, y1, x2, y2)¶

Parameters:

x1 (int) – a window coordinate;
y1 (int) – a window coordinate;
x2 (int) – a window coordinate;
y2 (int) – a window coordinate.

Returns:

an empty list if no node found, or a newly created list of ids if any.

Return type:

[int]

Get the v_sim.Node ids in the picked region defined by (x1, y1) - (x2, y2).

New in version 3.7.

renderAsBalls(factor)¶

Parameters:: factor (float) – a positive factor.

Setup all atomic rendering to use spheres. The radius of the spheres are taken as the covalent radius, times factor. All elements are made visible and their color is set to the default color for this element in the periodic table.

New in version 3.9.

setMaterialEffect(effect)¶

Parameters:: effect (v_sim.ElementRendererEffects) – a v_sim.ElementRendererEffects id.
Returns:: True if the effect has been changed.
Return type:: bool

Changes the effect applied on the color used to render v_sim.Element.

New in version 3.7.
