`shapelist3d.Rd`

These functions create and plot a list of shapes.

```
shapelist3d(shapes, x = 0, y = NULL, z = NULL, size = 1, matrix = NULL, override = TRUE,
..., plot = TRUE)
```

shapes | A single |
---|---|

x, y, z | Translation(s) to apply |

size | Scaling(s) to apply |

matrix | A single matrix transformation, or a list of them. |

override | Whether the material properties should override the ones in the shapes. |

... | Material properties to apply. |

plot | Whether to plot the result. |

`shapelist3d`

is a quick way to create a complex object made up of simpler ones.
Each of the arguments `shapes`

through `override`

may be a vector of
values (a list in the case of `shapes`

or `matrix`

). All values
will be recycled to produce a list of shapes as long as the longest of them.

The `xyz.coords`

function will be used to process the `x`

,
`y`

and `z`

arguments, so a matrix may be used as `x`

to
specify all three. If a vector is used for `x`

but `y`

or `z`

is missing, default values of `0`

will be used.

The `"shapelist3d"`

class is simply a list of `"shape3d"`

objects.

Methods for `dot3d`

, `wire3d`

, `shade3d`

,
`translate3d`

, `scale3d`

, and `rotate3d`

are defined for these objects.

An object of class `c("shapelist3d", "shape3d")`

.
