apply()#

apply(m, point): Point

Parameters#

m#

unknown

point#

Point

Returns#

Point

applyVector()#

applyVector(m, vector): Vector

Parameters#

m#

unknown

vector#

Vector

Returns#

Vector

compose()#

compose(a, b): Transformation

Compose: b first, then a (function-composition order).

Parameters#

a#

unknown

b#

unknown

Returns#

Transformation

invert()#

invert(m): Transformation

Inverse. A singular (non-invertible) matrix THROWS.

The old ?? identity() turned the kernel's "no inverse exists" into a perfectly plausible transform: apply(invert(scaling(0,1,1)), p) answered p itself, which is indistinguishable from a real inverse at every call site. There is no reading of a singular matrix that yields an inverse, so the failure is reported instead of guessed.

Parameters#

m#

unknown

Returns#

Transformation

rotation()#

rotation(axisOrigin, axisDirection, angleDeg): Transformation

Parameters#

axisOrigin#

Point

axisDirection#

Vector

angleDeg#

number

Returns#

Transformation

scaling()#

scaling(sx, sy, sz): Transformation

Parameters#

sx#

number

sy#

number

sz#

number

Returns#

Transformation

translation()#

translation(vector): Transformation

Parameters#

vector#

Vector

Returns#

Transformation
