Ensight -- Set Z Clipping

INTRODUCTION

As you apply zoom transformations in EnSight, you may have noticed that the model begins to progressively

disappear as you move close to the model. This happens when the visible model parts intersect the front Z clipping

planes. The Z-clip planes (which are always perpendicular to your line of sight) are specified as distances from the

look-from point (the camera position). The Z clipping plane positions can be set by the user and can be used to

remove unneeded geometry from the display. Each viewport has it’s own set of Z clipping planes. By default, the Zclip planes adjust (float) with the model - thus stay out of the way if possible.
