HOOPS Manipulations

Another feature of the HOOPS Graphics is the ability to adjust the graphics toolbar, for the purpose of rearranging or removing buttons. There are a number of ways to make these adjustments, as discussed here. The first method is to right click on the tool bar. This will bring up a button, shown in the figure to the right, which activates the modification dialog box.


Toolbar Adjustment Button

After clicking this [Customization Button], a dialog box is presented which allows for the removal or reordering of all toolbar buttons. Buttons can be removed by moving the selector in the right hand list box to the desired button, and clicking on the [Remove] button. (Removed items can be put back on the toolbar by selecting them in the left hand list box and clicking on the [Add] button.) Buttons can be reordered by selecting them and then clicking the [Move Up] or [Move Down] buttons. This modification dialog box is shown in the figure below.


Toolbar Modification Dialog

In addition to the use of this formal customization dialog, individual buttons can be removed or repositioned by holding down the [Shift] key, and dragging the necessary button. To remove a button, drag it off the graphics window, using the left mouse button. To reposition a button, drag it to the desired location, using the left mouse button.

AMultiple viewports is another User controllable feature of the HOOPS graphics. CAESAR II has provided the 4 Views graphics option for many years. This option however provides only four static views: X axis, Y axis, Z axis, and Isometric. The HOOPS graphics on the other hand provide up to 4 views, that can be sized, rotated, and annotated by the user.

The figure at the right shows the initial HOOPS view when these graphics are activated. Notice the two splitter bars, one at the far left of the lower scroll bar, and one at the very top of the right scroll bar.


Initial HOOPS Graphics View

Using the left mouse button, grab the lower left splitter bar and drag it to the right. This will split the graphics window into two panes, left and right. When the mouse button is released, both panes are updated, with the Z axis view in the left pane and the isometric (or original view) in the right pane. This modification to the graphics view is shown in the figure to the right.


HOOPS Graphics View - Vertical Split

Again using the left mouse button, grab the upper right splitter bar and drag it down. This will split the two existing panes into two additional panes, upper and lower. When the mouse button is released, all four panes are updated, with the Z axis view in the lower left pane, the isometric (or original view) in the lower right pane, the X axis view in the upper left pane, and the Y axis view in the upper right pane. This modification to the graphics view is shown in the figure to the right.

The image in all of these panes can be manipulated individually. Each pane can be rotated, panned, or zoomed independently of the other panes.
