Class: ThreeDAxes

Defined in: mobjects/three-d/ThreeDAxes.ts:85

ThreeDAxes - A 3D coordinate system with x, y, and z axes

Creates a 3D coordinate system with configurable ranges, colors, and styling. Supports coordinate transformations between graph space and visual space.

Example

// Create default 3D axes
const axes = new ThreeDAxes();

// Create axes with custom ranges
const customAxes = new ThreeDAxes({
xRange: [0, 10, 1],
yRange: [-1, 1, 0.5],
zRange: [0, 5, 1]
});

// Get a point in visual coordinates
const point = axes.coordsToPoint(3, 2, 1);

// Create colored axes
const coloredAxes = new ThreeDAxes({
xColor: '#ff0000',
yColor: '#00ff00',
zColor: '#0000ff'
});

shiftLabelsOntoScreen()

shiftLabelsOntoScreen(camera, margin): this

Defined in: mobjects/three-d/ThreeDAxes.ts:507

Manim CE's shift_onto_screen equivalent. Call once the scene/camera exist (e.g. after scene.add(axes) and a first render). Projects each axis label to normalized device coordinates using the supplied camera and, if the label sits outside the [-1, 1] viewport box, shifts it back along the vector to its axis tip until it lies inside.

Requires runtime access to the camera, which ThreeDAxes has no handle on at construction time — so this is an opt-in method rather than automatic.

Parameters

camera

Camera

The camera the scene is rendering with (perspective/ortho).

margin

number = 0.05

Fraction of NDC to keep as padding inside the viewport. Default 0.05 (5% margin).
