_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.
Parameters
points

targetCount

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
