_interpolatePointList3D()

protected _interpolatePointList3D(points, targetCount): number[][]

Defined in: core/VMobject.ts:531

Interpolate a 3D point list to have a specific number of points.

Delegates to the bezier-aware resamplePointList3D so that valid cubic Bezier chains are densified by de Casteljau subdivision rather than piecewise-linear interpolation. Linear lerp on cubic control points silently produces invalid handles (handle = midpoint of two adjacent controls), which renders as flat polygonal segments mid-Transform.

copy()

copy(): VMobject

Defined in: core/VMobject.ts:553

Create a copy of this VMobject. Subclasses override _createCopy() to produce an instance of the right concrete type (Circle, Square, etc.), but those constructors typically regenerate points from their own parameters (radius, sideLength, ...). After a Transform animation has morphed the point data, the regenerated points no longer match the actual visual state. We therefore always overwrite the clone's _points3D with the source's current data.

_toLinewidth()

static _toLinewidth(this, strokeWidth): number

Defined in: core/VMobjectRendering.ts:123

Convert Manim-compatible strokeWidth to LineMaterial linewidth in pixels. Python Manim uses cairo_line_width_multiple=0.01, so: linewidth_px = strokeWidth * 0.01 * (rendererWidth / frameWidth)

NOTE: This static method uses class-level statics. For multi-scene correctness, internal code should use the instance method _computeLinewidth().

Parameters

this

typeof VMobjectRendering

strokeWidth

number

Returns

number

Inherited from

ArrowTip._toLinewidth
