Each camera object you insert in your model has its own Camera window. When you look at your model from a Camera window, it's as though you are actually viewing it through the camera's viewfinder.
To view the model through the Camera window, double-click on the camera object's icon in the Modeling window, or select the camera object by name from the Camera Window command's pop-up menu in the Windows menu.
Camera windows are similar to Modeling windows, but they are linked to the camera objects. Each camera can contain only one view; Camera windows cannot be split.
The following controls are found at the top of the Camera window. Several of these are also available through the Object Properties palette and the Tool Settings dialog.
· Display method. Just like in the Project window - all available display methods appear in this list. Select the one you want to use from the pop-up list.
· Aspect ratio. This field indicates the ratio of the width of the Camera window to its height. You can select any aspect ratio listed in the pop-up menu. If you resize the Camera window to a size that does not match any of those aspect ratios listed, Custom appears as the selected aspect ratio.
· Perspective slider. The perspective slider on the Camera window is fully variable, instead of the three-position perspective selector on the modeling window. The slider control is located horizontally across the top of the window frame.
When positioned to the far left, the Camera window view is at maximum telephoto, which translates into essentially no perspective at all. When positioned to the far right, the Camera window is at ultra-wide angle. The view angle is so extreme in perspective that objects appear distorted.
If the redraw icon (pencil) appears in color, chances are good that the window needs to be refreshed.
· View grid. Each camera view contains a View Grid button. Unlike other grids in Strata 3D, these grids are view-relative, so they track whenever you move in the window. They are drawn parallel to the view plane with a coordinate system of 0,0,0. View grids appear gray in the Camera window.
· Constrain Roll. When this option is enabled, the camera's "up" vector always remains in the "up" position. Click the button again to disable this option.
· Lock/Unlock. You can lock the aspect ratio so that resizing the window prevents the ratio from changing.
