Simple Visualization Classes

2D Grid Class

The 2D Grid class adds a simple 2D grid into the 3D scene. The controls for a grid are shown in Figure 134. The number of rows and columns can be controlled with the # Rows and # Cols textfields. When a grid is added to the current scene, it will cover the entire geo-referenced area. By default, the grid will display in the middle of the depth range, but can be moved to the top or bottom of the depth range using the Top and Bottom toggle buttons. The Grid Color button is used to control the display color of the grid.

2D Plane Class

The 2D Plane class adds a simple 2D colored plane (rectangle) into the 3D scene. For example, a transparent blue plane could be added to a scene to represent the sea surface. This class is very useful in applications such as dredging where you have a DTM and want to make sure the channel is deeper than a specified depth. Adding a plane at the depth makes it obvious to see any parts of the DTM that are higher than the plane. This type of object is often used with the Fledermaus surface query command. For example, queries between a plane and a surface are common to find out how much material must be dredged as in the example above.

The geographic height of the plane is controlled by the user by entering a value in the Height textfield and selecting the Use Geo. Height toggle, located on the 2D Plane control panel shown in Figure 135. To change the color or transparency of the plane, click the Set Color or adjust the Transparency slider respectively.

Label Class

The Label class provides a simple way to add a textual label into the 3D scene and arbitrarily position it.

The text used for the label can be controlled with the Label textfield, as shown in Figure 136. Also, the line width and color can be controlled with the Line Width textfield and Label Color button respectively.

CUBE Class

This rudimentary class adds a simple solid cube into the scene. This object is occasionally used to mark areas of interest in the 3D scene but has limited usefulness beyond that.

Quadratic Class

The quadratic class provides for the visualization of a sphere, disk, or cone object. These objects are sometimes useful to have to act as markers of other solid entities within the 3D scene. Controls provide options for the quality, color, and construction of the desired quadratic shape.
