Class Camera
java.lang.Objectcom.xerox.VTM.engine.Camera
- public class Camera
- extends java.lang.Object
a Camera is used to observe the virtual space which owns it - all cameras have unique IDs, as glyph - (x,y) coordinates, observation altitude and focal distance can be changed
| Field Summary | |
float |
altitude
altitude of observation |
(package private) boolean |
eager
Lazy camera, true if the camera only repaints when explicitely asked |
(package private) boolean |
enabled
camera is enabled or not (disabling does not destroy) |
float |
focal
focal distance |
(package private) java.lang.Integer |
ID
camera ID |
(package private) int |
index
camera index (wrt the owning virtual space) |
(package private) VirtualSpace |
parentSpace
virtual space to which this camera belongs to |
long |
posx
coordinates in virtual space |
long |
posy
coordinates in virtual space |
(package private) boolean |
shouldRepaint
when in lazy mode, tells the camera to repaint next time the owning view goes through its paint loop |
(package private) View |
view
View using this camera as one of its layer(s) |
