7.2.17 camera-prop

(camera-prop { geometry object } [projective])

Specify the objeto to be shown when drawing other câmeras. By default, this objeto is drawn with its origin at the camera, and with the câmera looking toward the objeto's -Z axis. With the projective keyword, the camera's viewing projection is also applied to the objeto; this places the objeto's Z=-1 and Z=+1 at near and far clipping planes, with the viewing area -1<={X,Y}<=+1. Example: (camera-prop { < cube } projective)
