ellipsoids with the half axes a, b, c about their centres, in a 3D scene; MATLAB’s plotEllipsoid

Syntax

a, b, c = grains.principalComponents()

plotEllipsoid(grains.centroid, a, b, c, faceColor='r')

The ellipsoids of the grains.

plotEllipsoid(grains.centroid, a, b, c, faceColor=rgb, edgeAlpha=0)

A colour each, no edges.

Description

Every ellipsoid is a surface on a grid of 24 longitudes and 12 latitudes. With hold on it joins the grains of the scene drawn before. The plot is a scene3d held by the mtexFigure, shown as the picture PyVista renders offscreen (matplotlib’s 3D axes without PyVista), so hold, setCamera and mtexColorbar act on it as on any MTEX figure; show3d opens it in a window and exportHTML writes it as an interactive page.

Input

`center`	vector3d, the centres
`a`	vector3d, the first half axis of every ellipsoid
`b`	vector3d, the second half axis
`c`	vector3d, the third half axis

Keywords

keyword	default	description
`faceColor`	`'lightblue'`	the colour of the ellipsoids, one for all or an (n, 3) array of RGB values one per ellipsoid
`edgeAlpha`	`0.25`	the opacity of the grid lines on the surfaces
`how2plot`	`None`	the plottingConvention of the view, by default plottingConvention.default3D
`figSize`	`None`	the size of a new figure, ‘small’, ‘normal’, ‘large’, …, or (width, height) in inches

Output
