k3d.factory.label(text, position=(0, 0, 0), color=255, on_top=True, size=1.0, max_length=0.8, mode='dynamic', is_html=False, label_box=True, name=None, group=None, custom_data=None, compression_level=0, **kwargs)[source]#

Create a Text drawable for 3D-positioned text labels.

Parameters

  • text (str or list of str) – Content of the text.

  • position (list) – (x, y, z) coordinates of text position, by default (0, 0, 0). If n text is pass position should contain 3*n elements .

  • color (int, optional) – Hex color of the text, by default _default_color.

  • on_top (bool, optional) – Render order with 3d object, by default True.

  • size (float, optional) – Font size in ‘em’ HTML units, by default 1.0.

  • name (str, optional) – Object name, by default None.

  • group (str, optional) – Name of a group, by default None.

  • max_length (float, optional) – Maximum length of line in % of half screen size (only when mode is dynamic), by default 0.8.

  • mode ({'dynamic', 'local', 'side'}, optional) – Label node, by default “dynamic”.

  • is_html (bool, optional) – Interprete text as HTMl instead of KaTeX, by default False.

  • label_box (bool, optional) – Label background box, by default True.

  • custom_data (dict) – A object with custom data attached to object.

  • compression_level (int, optional) – Level of data compression [-1, 9], by default 0.

  • **kwargs – For other keyword-only arguments, see process_transform_arguments.
