Transforms a point from layer space to view-independent world space. Example:
to World. e f fe c t ("Bu l ge" )("Bu lge
C enter")
Return type: Array [2 or 3].
fromWorld(point, t=time)
Argument type: point is an Array [2 or 3], and t is a Number.
Transforms a point from world space to layer space. Example:
f rom World(t hisC omp. layer(2).p osit ion)
Return type: Array [2 or 3].
toCompVec(vec, t=time)
Argument type: vec is an Array[2 or 3], and t is a Number.
Transforms a vector from layer space to composition space. Example:
toC ompVe c ([1, 0])
Return type: Array [2 or 3].
fromCompVec(vec, t=time)
Argument type: vec is an Array[2 or 3], and t is a Number.
Transforms a vector from composition space to layer space. Example (2D layer):
dir=sub(p osit ion, t hisC omp.layer(2).p osit ion); f romC ompVe c(dir)
Return type: Array [2 or 3].
toWorldVec(vec, t=time)
Argument type: vec is an Array[2 or 3], and t is a Number.
Transforms a vector from layer space to world space. Example:
p1 = ef fe c t("Eye Bu lge 1")("Bu lge C enter"); p2 = ef fe c t("Eye Bu lge 2")("Bulge C enter"); toWorld(sub(p1, p2))
Return type: Array [2 or 3].
fromWorldVec(vec, t=time)
Argument type: vec is an Array [2 or 3], and t is a Number.
Transforms a vector from world space to layer space. Example:
f rom World(t hisC omp. layer(2).p osit ion)
Return type: Array [2].
fromCompToSurface(point, t=time)
Argument type: point is an Array [2 or 3], and t is a Number.
Projects a point located in composition space to a point on the surface of the layer (zero z-value) at the location where
it appears when viewed from the active camera. This is useful for setting effect control points. Use with 3D layers
only.
