INTRODUCTION
In addition to providing control over model manipulations, EnSight also provides control over the virtual camera used
to view the scene in the Graphics Window while in Global Transform Mode. If a viewport is being viewed through a
camera, this section is not applicable. The two control parameters are the look-from point (the position of the
camera) and the look-at point (a point on the camera’s line-of-sight vector). The Global Axis is positioned at the lookat point and is always in the center of the Graphics Window.
Initially, the look-at point is set to the geometric center of all visible objects and the look-from point is set to a point on
the positive Z axis such that all visible objects fit in the Graphics Window (as shown in the top image below). The
white axis triad is the Global Axis and can be displayed by selecting View > Axis Visibility > Axis - Global. The bottom
image shows the view after the look-from point has been repositioned between the X and Z axes. The diagrams to
the right of each image show a top-down schematic of each viewing case.
