the reference frame indicator MTEX draws in the scale bar box, with the text height t as its unit: an arrow per axis that has a direction on screen, shortened by its tilt out of the plane, a circle for an axis leaving the plane with its label inside, crossed by four spokes when it points away from the viewer, and a label beside every arrow. Returns the arrows as polygons, the symbol as a polyline with NaN breaks, the labels with their positions, and the bounding box (umin, umax, vmin, vmax)

Syntax

arrows, symbol, texts, bbox = triadGeometry(frameOnScreen(pl), ['x', 'y', 'z'])

In text heights.

arrows, symbol, texts, bbox = triadGeometry(screen, labels, t=2.0)

Twice as large.

Input

screen the (right, up, out) triples of the axes, frameOnScreen
labels the label of every axis

Keywords

keyword default description
t 1.0 the height of the text, the unit of the drawing

Output

arrows a list of polygons of shape (7, 2)
symbol array of shape (m, 2), the circle and its spokes, NaN rows between pieces
texts a list of (position, label)
bbox (umin, umax, vmin, vmax)
