r"""
Visualize the Coloured TriMesh in 3D.
Parameters
----------
figure_id : `object`, optional
The id of the figure to be used.
new_figure : `bool`, optional
If ``True``, a new figure is created.
render_texture : `bool`, optional
If ``True``, then the texture is rendered. If ``False``, then only
the TriMesh is rendered with the specified `colour`.
mesh_type : ``{'surface', 'wireframe'}``, optional
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.
normals_colour : See Below, optional
The colour of the normals.
Example options ::
{r, g, b, c, m, k, w}
or
(3, ) ndarray
normals_line_width : `float`, optional
The width of the lines of the normals. It only applies if `normals`
is not ``None``.
normals_marker_style : `str`, optional
The style of the markers of the normals. It only applies if `normals`
is not ``None``.
Example options ::
{2darrow, 2dcircle, 2dcross, 2ddash, 2ddiamond, 2dhooked_arrow,
2dsquare, 2dthick_arrow, 2dthick_cross, 2dtriangle, 2dvertex,
arrow, axes, cone, cube, cylinder, point, sphere}
normals_marker_resolution : `int`, optional
The resolution of the markers of the normals. For spheres, for
instance, this is the number of divisions along theta and phi. It
only applies if `normals` is not ``None``.
normals_marker_size : `float` or ``None``, optional
The size of the markers. This size can be seen as a scale factor
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.
If ``None``, then all vertexes will be rendered. It only applies if
`normals` is not ``None``.
alpha : `float`, optional
Defines the transparency (opacity) of the object.
Returns
-------
renderer : `menpo3d.visualize.ColouredTriMeshViewer3D`
The Menpo3D rendering object.
