Controlling view of camera view area Pay attention to these buttons on the toolbar. These buttons flexibly control views of camera view areas on the layout and in 3D. The View area edges button controls visibility of the edges of the view area on the layout. The edges are displayed on the projection in the form of aqua color lines The Fill projections button toggles the fill type of the view area projection. There may be filling,
hatching Or no filling. The View area projection bounds button controls visibility of the boundaries of the view area projections, constructed without taking into account shading. The boundaries are displayed as olive lines. The Spatial resolution button controls visualization of the spatial resolution of the camera. There will be special video tutorial about the spatial resolution. You can choose discrete colors, Gradient, Or lack of visualization. The result depends on the state of the Fill projection button. If you select Hatching, the visualization will look like this. The Shadow button controls visualization of shading from surrounding objects. There will be special video tutorial about the shadows. You can select Within the projection in the menu of the button. We draw rectangles and shadows from them are shown on the view area projection. By choosing Dome we can show shadows in all directions from the camera, thus showing the control zone of a PTZ camera. The view of shadows depends on the position of the other buttons. These dependencies are described in detail in the help system. Thus, the view areas of different cameras can be displayed on the layout in different ways, according to the purpose of each camera This can be seen in the demo project. We delete the rectangles. The 3D view area button controls visibility of the view area in three-dimensional view from the side. In VideoCAD Lite, this button controls visibility of the view area through other cameras in the 3D Video window. Let’s see how it works. Let’s suppose we have several cameras. Open the 3D Video window. Turn on visibility of the view areas of other cameras. We see the 3D view area of camera 1 through camera 2. With this button, we can turn off visibility of the view area of camera 1. If there are no selected cameras, then the considered buttons affect only on the active camera. If there are selected cameras other than the active one, then the buttons are painted in crimson color and their effect extends to all selected cameras simultaneously. Thus, it is convenient to control view of the view area of both a single active camera and any number of selected cameras. We worked in VideoCAD Lite In VideoCAD Professional, the horizontal projection of the view area can be displayed in two sections Section on the height of the view area upper bound is displayed in the form of hatching And the section on the height of the view area lower bound is displayed in the form of a filling If you select hatching, the hatching and filling will be swapped. Spatial resolution is visualized at the lower section. Shading is also shown on the two sections independently. This rectangle, 2 meters high Crosses only the lower bound of the view area. A little increase the height of the rectangle and now it crosses the upper bound of the view area too. The visualization in the form of two sections more informatively represents the 3D view area on the horizontal projection, especially in non-standard camera positions. Let’s see how the view area projection is changed with changing the height of camera installation. In the Professional version, the 3D view areas of all cameras are displayed in the 3D World window. These buttons control 3D displaying the view areas. In addition to these buttons, there are settings of the view area view in the 3D World window. The lesson is over Thank you for your attention
