The id of the figure to be used.
new_figure : `bool`, optional
If ``True``, a new figure is created.

If ``True``, then the texture is rendered. If ``False``, then only
the TriMesh is rendered with the specified `colour`.

The representation type to be used for the mesh.
ambient_light : `float`, optional
The ambient light intensity. It must be in range ``[0., 1.]``.
specular_light : `float`, optional
The specular light intensity. It must be in range ``[0., 1.]``.
colour : See Below, optional
The colour of the mesh if `render_texture` is ``False``.
Example options ::
{r, g, b, c, m, k, w}
or
(3, ) ndarray
line_width : `float`, optional
The width of the lines, if there are any.
normals : ``(n_points, 3)`` `ndarray` or ``None``, optional
If ``None``, then the normals will not be rendered. If `ndarray`,
then the provided normals will be rendered as well. Note that a
normal must be provided for each point in the TriMesh.

The colour of the normals.
Example options ::

applied to the size markers, which is by default calculated from
the inter-marker spacing. If ``None``, then an optimal marker size
value will be set automatically. It only applies if `normals` is not
``None``.
step : `int` or ``None``, optional
If `int`, then one every `step` normals will be rendered.
