Scene management

Description

Clear shapes, lights, bbox

Usage

clear3d( type = c("shapes", "bboxdeco", "material"), defaults, subscene = 0 ) 
pop3d( type = "shapes", id = 0 )
ids3d( type = "shapes", subscene = NA )

Arguments

`type`	Select subtype(s): "shapes" shape stack "lights" light stack "bboxdeco" bounding box "userviewpoint" user viewpoint "modelviewpoint" model viewpoint "material" material properties "background" scene background "subscene" subscene list "all" all of the above
`defaults`	default values to use after clearing
`subscene`	which subscene to work with. `NA` means the current one, `0` means the whole scene
`id`	vector of ID numbers of items to remove

Details

RGL holds several lists of objects in each scene. There are lists for shapes, lights, bounding box decorations, subscenes, etc. clear3d clears the specified stack, or restores the defaults for the bounding box (not visible) or viewpoint. With id = 0 pop3d removes the last added node on the list (except for subscenes: there it removes the active subscene). The id argument may be used to specify arbitrary item(s) to remove; if id != 0, the type argument is ignored.

clear3d may also be used to clear material properties back to their defaults.

clear3d has an optional defaults argument, which defaults to r3dDefaults. Only the materials component of this argument is currently used by clear3d.

ids3d returns a dataframe containing the IDs in the currently active subscene by default, or a specified subscene, or if subscene = 0, in the whole rgl window, along with an indicator of their type.

Note that clearing the light stack leaves the scene in darkness; it should normally be followed by a call to light3d or light3d.

Examples

x <- rnorm(100)
  y <- rnorm(100)
  z <- rnorm(100)
  p <- plot3d(x, y, z, type = 's')
  ids3d()
  lines3d(x, y, z)
  ids3d()
  if (interactive() && !rgl.useNULL()) {
    readline("Hit enter to change spheres")
    pop3d(id = p["data"])
    spheres3d(x, y, z, col = "red", radius = 1/5)
    box3d()
  }
