A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.

1. A method for providing a computer-generated view of at least a first articulatable instrument extending out of a distal end of an entry guide, the first articulatable instrument having a most proximal joint and a most distal joint, the most distal joint disposed beyond the distal end of the entry guide, the method comprising: receiving information of states of the entry guide and the first articulatable instrument;generating the computer-generated view to include a graphical representation of the most distal joint of the first articulatable instrument and a graphical representation of a spatial boundary for the first articulatable instrument, the spatial boundary being a function of a position of the most distal joint relative to the distal end of the entry guide, and the graphical representations being positioned in the computer-generated view by using the received information and by using forward kinematics of the entry guide and the first articulatable instrument; anddisplaying the computer-generated view on a display screen. 2. The method according to claim 1, wherein the computer-generated view is generated from a perspective looking in a distal direction from the distal end of the entry guide. 3. The method according to claim 1, wherein the first articulatable instrument comprises: first, second, and third links; anda second joint;wherein the most proximal joint couples a distal end of the first link to a proximal end of the second link so that the second link is rotatable relative to the first link at the most proximal joint;wherein the second joint couples a distal end of the second link to a proximal end of the third link so that the third link rotates relative to the second link at the second joint in tandem with rotation of the most proximal joint in such a fashion that longitudinal axes of the first and third links are parallel to each other;wherein the distal end of the entry guide has a first lumen;wherein the first articulatable instrument extends through the first lumen;wherein the computer-generated view includes at least one of an outline of the distal end of the entry guide and a graphical representation of the most proximal joint of the first articulatable instrument; andwherein the graphical representation of the most proximal joint of the first articulatable instrument appears in the computer-generated view as a first object that is positioned in the computer-generated view where the first lumen would be relative to the outline of the distal end of the entry guide when the computer-generated view includes the graphical representation of the most proximal joint of the first articulatable instrument. 4.
