rgl (version 0.83-3)

rgl-package: 3D visualization device system

Description

3D real-time rendering system.

Usage

# Low level rgl.* interface
rgl.open()     # open new device
rgl.close()    # close current device
rgl.cur()      # returns active device ID
rgl.set(which, silent=FALSE) # set device as active
rgl.quit()     # shutdown rgl device system
rgl.init(initValue=0)     # re-initialize rgl

Arguments

which

device ID

silent

whether to suppress update of window titles

initValue

value for internal use only

Details

RGL is a 3D real-time rendering device driver system for R. Multiple devices are managed at a time, where one has the current focus that receives instructions from the R command-line. The device design is oriented towards the R device metaphor. If you send scene management instructions, and there's no device open, it will be opened automatically. Opened devices automatically get the current device focus. The focus may be changed by using rgl.set(). rgl.quit() shuts down the rgl subsystem and all open devices, detaches the package including the shared library and additional system libraries. If rgl.open() fails (e.g. because X windows is not running, or its DISPLAY variable is not set properly), then you can retry the initialization by calling rgl.init(). Do not do this when windows have already been successfully opened: they will be orphaned, with no way to remove them other than closing R. In fact, it's probably a good idea not to do this at all: quitting R and restarting it is a better solution.

This package also includes a higher level interface which is described in the r3d help topic. That interface is designed to act more like classic 2D R graphics. We recommend that you avoid mixing rgl.* and *3d calls.
