Midwater Beam Curtain

Introduction

The object is very similar to the vertical curtain with the main difference that both to top and bottom of the imagery can be given a location thus the certain can be tilted to any angle. This is normally used in conjunction with FMMidwater application to write out an imagery curtain for particular beams from a multibeam system. One can think of rendering a column of pixels for a given beam for each ping fan in the navigation line. If you join all those columns of pixels together you end up with a beam curtain that is tilted based on the beam angle.

Properties

Attributes

The Time control dropdown menu controls how much of the overall beam curtain to show. It can be one of All Points, Past Points, Points Within a Window. All Points shows the entire beam curtain, Past Points shows the curtain from the start time to the currently selected scene time, and Points Within a Windows shows the curtain within the selected time window around the current scene time.

The Transparency slider allows one to have the curtain rendered with some blending of object behind the curtain based on the amount of object transparency set.

The Show Edges shows a an outline around the overall beam curtain object.

Operations
