Contour properties

To show the properties of a contour in the Property Panel, select the contour from the Object Explorer. The Property Panel displays the properties of the contour as shown in Figure 1.

   

Figure 1: Contour “Outer” is selected in the Object Explorer and the Property Panel displays its properties.

Name

To change the name of the selected contour, click on its current value in the Property Panel to edit it. Insert the new value and press Enter. Alternatively, rename a contour directly in the Object Explorer. Select the contour from the Object Explorer and then left click on it to edit the name (notice this is not the same as double clicking).

Closed

This property determines whether the contour is a closed curve or not. Change it by selecting the desired value from the combo box as shown in Figure 2. When a contour is closed, select the value True for the Closed property, BioVis3D joins the extreme nodes of the contour to make it a closed curve (see Figure 2.)

Area

This property shows the area delimited by a closed contour measured in the unit specified by the Unit of Measure sequence property. To compute its value click Calc, which appears after clicking on the property.

Note: When a contour is modified, the value of this property appears empty until Calc is clicked again to update the area.

Note: If the contour is not closed, a message appears asking the user to close the contour in order to compute the area.

Perimeter

This property shows the perimeter of a contour measured in the unit specified by the Unit of Measure sequence property. To compute its value click Calc which appears after clicking on the property.

Note: When a contour is modified, the value of this property appears empty until Calc is clicked again to update the perimeter.
