◆ Apply()

void TGLPerspectiveCamera::Apply	(	const TGLBoundingBox &	sceneBox,
		const TGLRect *	pickRect = `0`

virtual

Apply the camera to the current GL context, setting the viewport, projection and modelview matrices.

After this vertices etc can be directly entered in the world frame. This also updates the cached frustum values, enabling all the projection, overlap tests etc defined in TGLCamera to be used.

Arguments are:

'box' - view volume box - used to adjust near/far clipping
'pickRect' - optional picking rect. If non-null, restrict drawing to this viewport rect.

Implements TGLCamera.

		Double_t	dolly,
		Double_t	center[3],
		Double_t	hRotate,
		Double_t	vRotate
	)

virtual

Configure the camera state.

fov - set directly field-of-view in degrees (default = 30);
dolly - additional move along the camera forward direction;
center - new camera center (can be 0 for no change);
hRotate - additional "up/down" rotation in radians;
vRotate - additional "left/right" rotation in radians.

Implements TGLCamera.
