# Alignable class

class Alignable a where Source #

Class of things which can be aligned.

alignBy' :: (InSpace v n a, Fractional n, HasOrigin a) => (v n -> a -> Point v n) -> v n -> n -> a -> a Source #

`alignBy v d a`

moves the origin of `a`

along the vector
`v`

. If `d = 1`

, the origin is moved to the edge of the
boundary in the direction of `v`

; if `d = -1`

, it moves to the
edge of the boundary in the direction of the negation of `v`

.
Other values of `d`

interpolate linearly (so for example, ```
d =
0
```

centers the origin along the direction of `v`

).

# General alignment functions

align :: (InSpace v n a, Fractional n, Alignable a, HasOrigin a) => v n -> a -> a Source #

`align v`

aligns an enveloped object along the edge in the
direction of `v`

. That is, it moves the local origin in the
direction of `v`

until it is on the edge of the envelope. (Note
that if the local origin is outside the envelope to begin with,
it may have to move "backwards".)

snug :: (InSpace v n a, Fractional n, Alignable a, Traced a, HasOrigin a) => v n -> a -> a Source #

Like align but uses trace.

centerV :: (InSpace v n a, Fractional n, Alignable a, HasOrigin a) => v n -> a -> a Source #

`centerV v`

centers an enveloped object along the direction of
`v`

.

center :: (InSpace v n a, Fractional n, Traversable v, Alignable a, HasOrigin a) => a -> a Source #

`center`

centers an enveloped object along all of its basis vectors.

snugBy :: (InSpace v n a, Fractional n, Alignable a, Traced a, HasOrigin a) => v n -> n -> a -> a Source #

Version of `alignBy`

specialized to use `traceBoundary`

snugCenterV :: (InSpace v n a, Fractional n, Alignable a, Traced a, HasOrigin a) => v n -> a -> a Source #

Like `centerV`

using trace.

snugCenter :: (InSpace v n a, Traversable v, Fractional n, Alignable a, HasOrigin a, Traced a) => a -> a Source #

Like `center`

using trace.
