Interface: CoordinateSystem

Defined in: src/mobjects/graphing/CoordinateSystem.ts:15

CoordinateSystem - the shared surface of every coordinate system.

In ManimCE (manim/mobject/graphing/coordinate_systems.py) CoordinateSystem is the abstract base of Axes and NumberPlane. manim-web does not need that class hierarchy, because Axes is concrete and NumberPlane extends Axes. This interface captures the coordinate-conversion surface that both classes share, so callers can program against the abstraction. Axes declares implements CoordinateSystem, so the compiler checks the surface stays in sync, and NumberPlane inherits it.

Methods

c2p()

c2p(x, y): Vector3Tuple

Defined in: src/mobjects/graphing/CoordinateSystem.ts:19

Shorthand for coordsToPoint (matches ManimCE c2p).

Parameters

x

y

number

Returns

Vector3Tuple

---

c2pX()

c2pX(x): number

Defined in: src/mobjects/graphing/CoordinateSystem.ts:23

The x value of coordsToPoint(x, 0).

Parameters

x

number

Returns

number

---

c2pY()

c2pY(y): number

Defined in: src/mobjects/graphing/CoordinateSystem.ts:25

The y value of coordsToPoint(0, y).

Parameters

y

number

Returns

number

---

coordsToPoint()

coordsToPoint(x, y): Vector3Tuple

Defined in: src/mobjects/graphing/CoordinateSystem.ts:17

Map coordinates (x, y) to a point in scene space.

Parameters
