Create and plot a list of shapes

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)

Arguments

shapes

A single shape3d object, or a list of them.

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.

Details

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.

Value

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