Reduce number of patch faces

`reducepatch(p,r)`

nfv = reducepatch(p,r)

nfv = reducepatch(fv,r)

nfv = reducepatch(p)

nfv
= reducepatch(fv)

reducepatch(...,'fast')

reducepatch(...,'verbose')

nfv = reducepatch(f,v,r)

[nf,nv] = reducepatch(...)

`reducepatch(p,r)`

reduces the number of
faces of the patch identified by handle `p`

, while
attempting to preserve the overall shape of the original object. The MATLAB^{®} software
interprets the reduction factor `r`

in one of two
ways depending on its value:

If

`r`

is less than 1,`r`

is interpreted as a fraction of the original number of faces. For example, if you specify`r`

as 0.2, then the number of faces is reduced to 20% of the number in the original patch.If

`r`

is greater than or equal to 1, then`r`

is the target number of faces. For example, if you specify`r`

as 400, then the number of faces is reduced until there are 400 faces remaining.

`nfv = reducepatch(p,r)`

returns the reduced set of faces and vertices but does not set the `Faces`

and `Vertices`

properties
of patch `p`

. The struct `nfv`

contains
the faces and vertices after reduction.

`nfv = reducepatch(fv,r)`

performs
the reduction on the faces and vertices in the struct `fv`

.

`nfv = reducepatch(p)`

and ```
nfv
= reducepatch(fv)
```

uses a reduction value of `0.5`

.

`reducepatch(...,'fast')`

assumes
the vertices are unique and does not compute shared vertices.

`reducepatch(...,'verbose')`

prints progress messages to the command window as the computation
progresses.

`nfv = reducepatch(f,v,r)`

performs
the reduction on the faces in `f`

and the vertices
in `v`

.

`[nf,nv] = reducepatch(...)`

returns
the faces and vertices in the arrays `nf`

and `nv`

.
