viewpoint 51 Details Value The adj parameter determines the position of the text relative to the specified coordinate. Use adj = 0 to place the left bottom corner at (x,y,z), adj = 0.5 to center the text there, and adj = 1 to put the right bottom corner there. text3d and texts3d draw text using the r3d conventions. These are synonyms; the former is singular to be consistent with the classic 2-D graphics functions, and the latter is plural to be consistent with all the other graphics primitives. Take your choice! See Also If any coordinate or text is NA, that text is not plotted. The object ID of the text object is returned invisibly. r3d Examples open3d() text3d(rnorm(10)*100,rnorm(10)*100,rnorm(10)*100,text=1:10,adj = 0.5, color=heat.colors(10)) viewpoint Set up viewpoint Description Usage Set the viewpoint orientation. view3d( theta = 0, phi = 15, ...) rgl.viewpoint( theta = 0, phi = 15, fov = 60, zoom = 1, scale = par3d("scale"), interactive = TRUE, userMatrix ) Arguments theta,phi polar coordinates ... additional parameters to pass to rgl.viewpoint fov zoom scale interactive userMatrix field-of-view angle zoom factor real length 3 vector specifying the rescaling to apply to each axis logical, specifying if interactive navigation is allowed 4x4 matrix specifying user point of view
