Displays a point at the current animation time. Specifies one of the following graphics that will represent the trajectory of the point over time.
No visual representation of the vector is drawn. A 2D point is displayed on the 3D window, without a line. A 2D line is drawn with a point at the end instead of an arrow. A 3D arrow is drawn representing the vector. A 2D arrow is drawn representing the vector.ģD. You can choose one of five arrow types:ĢD. Specifies the arrow type used to represent the geometric element. Specifies the display color for the selected geometric element.Īrrow. Only available for vectors represented in distance units.Ĭolor. If selected, displays vectors at their true length. If selected, the magnitude value is displayed on the selected geometric element. If selected, displays the supporting arcs for the dihedral angle. If selected, choose a unit from the drop-down menu. Displays the cartesian orbital values for the selected point. Displays right-ascension and declination values with the selected vector. Translucency can be adjusted from 0 to 100 percent, where 100 percent is completely invisible. Use the slide control to set the translucency of the plane. If enabled, the plane is see-through otherwise it is opaque. Only available for planes ( ) and points ( ). Size of the selected geometric plane or point. Displays a text label with the selected geometric element. When the Draw at Point option is used for vectors or axes on objects, the Level of Detail (LOD) values will be ignored. Only available for vectors ( )and axes ( ). Geometric element is drawn at the selected point. If selected, the geometric element is drawn at the central body or object. Only available for geometric elements relating to objects. Use the button to access the Reference Axes/System Selection window where you can choose the axes/system that defines the coordinate frame to which the display options are applied.ĭraw at Central Body/Object. The name of the axes or system used to define the coordinate frame associated with the selected vector or axis is displayed in the text box. The properties for the selected element display to the right of the table.Īxes/System. To edit the properties of a geometric element, select it and select Show. Use to define the display of geometric elements in the 3D Graphics window. Displays the geometric element in the 3D Graphics window and enables you to modify the following display options. The elements available depend on the object or window for which Vector properties are being defined. This table column lists all of the following geometric elements available for display. Control the display of vectors and other geometric elements related to the selected object.Control the display of vectors and other geometric elements, such as axes and angles, related to the Earth or other central body in the selected 3D Graphics window.Note that if you are considering a system of differential equations, you also have the option of changing the notation of the components of the vector field to use differential notation. But when in 3D mode, you'll want to change the number of levels along the \(z\)-axis to be more than one. When in 2D mode, we just need to adjust the number of vectors along the \(x\)- and \(y\)-axes, and keep just one vector along the \(z\)-axis. The Number of vectors along each axis can be adjusted to change the appearance and refinement of the vector field. To see all vectors in the vector field at the natural length, change this value to 1. You can adjust this value to see how it affects the plot. By default, vectors in a vector field are divided by 4 to scale them down. It should appear like Figure 2.3.4.Īnother way to vary the vector lengths in a vector field so that they do not overlap is to adjust the scalefactor, labeled Scale vectors by dividing by. Select the checkbox labeled Use fixed length for all vectors to see how this looks. One option is to force all vectors in the vector field to have the same fixed length. There are a couple options for dealing with this. This vector field is still fairly easy to read, but sometimes the vectors may be very difficult to read because of how they overlap. 2D vector field with fixed length vectors
