Make the scene appear larger or smaller. Provided as a convenience to simplify application code. Values greater than 1 make the scene appear larger. Values less than 1 make the scene appear smaller. For example a of 2 will make the scene approximately 2 times larger in the rendering window. The specific effect on the camera is a 'dolly' or a 'zoom' depending on the type of camera. This is often useful after calling ViewAll(). That method sets the camera parameters based on a bounding sphere around the scene which often leaves the scene not "filling" the viewport. Details: - SoPerspectiveCamera: changes the camera 'position' field. For example, values greater than 1 move the camera closer to the focal point (divide the camera's distance from the focal point by the given value), which makes the scene appear larger. This is a 'dolly'. - SoOrthographicCamera: changes the camera 'height' field. For example, values greater than 1 decrease the view volume height (scale the height by the inverse of the given value), which makes the scene appear larger. This is a 'zoom' operation. Note that the value expected by SoCameraInteractor.Dolly is the inverse, which is less intuitive.
