spin: Spin or rotate a 3D plot

In p3d: Plot 3d data and fitted surfaces

Description

Like rgl.viewpoint but starts with defaults from par3d, except for theta (rotation around vertical axis) and phi (angular height above the horizontal plane)

Usage

spin(theta = 0, phi = 15, fov = par3d("FOV"), zoom = par3d("zoom"), scale = par3d("scale"), stay = FALSE)

Arguments

theta	rotation around vertical axis
phi	angular height above the horizontal plane
fov
zoom	Zoom factor, passed to link[rgl]{rgl.viewpoint}
scale	Scale factor, passed to link[rgl]{rgl.viewpoint}
stay	Not used in this implementation.

Value

None.

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function( theta=0, phi=15,
          fov = par3d("FOV"), zoom = par3d("zoom"), 
          scale = par3d("scale"), stay = FALSE) {
          
          # Like rgl viewpoint but starts with defaults except
          # for theta (rotation around vertical axis)
          # and phi (angular height above the horisontal plane) 
          # PLAN:
          # without arguments it should just start spinning
          # USAGE: see rgl.viewpoint and rgl.snapshot
          # rgl.bringtotop(stay = FALSE)
          rgl.viewpoint( theta=theta, phi = phi,
                fov = fov, zoom = zoom, scale = scale)

  }
