Properties of a camera floating around in space, or, alternatively, an eagle's eye.

vector Eagle::Camera::getLookAt ( ) const [inline]

Get the point which is currently looked at.

This point resides in the focalDistance from the Camera. During stereographic rendering, it is kept at the same pixel.

double Eagle::Camera::getViewAngle ( ) const [inline]

What is the current horizontal view angle of the camera?

void Eagle::Camera::look_right ( double radians ) [inline]

Roll the camera to look right a little bit.

Parameters:

radians How many radians are "a little bit". The camera position is unchanged.

void Eagle::Camera::look_up ( double radians ) [inline]

Roll the camera to look up a little bit.

Parameters:

radians How many radians are "a little bit". The camera position is unchanged.

void Eagle::Camera::move_forward ( double dist ) [inline]

Move the camera forward a little bit.

Parameters:

How	much is a little bit. Note that the focal distance is kept constant, i.e. we do not move closer to the getLookAt() point but keep our eyes constant when moving forward.

void Eagle::Camera::move_right ( double dist ) [inline]

Move (shift) the camera right a little bit.

Parameters:

How	much is a little bit. See getRightDir() on how "right" is defined.

void Eagle::Camera::move_up ( double dist ) [inline]

Move (raise) the camera up little bit.

Parameters:

How	much is a little bit. See getUpDir() on how "up" is defined.

void Eagle::Camera::setViewAngle ( double va ) [inline]

Specify the current horizontal view angle of the camera.

Parameters:

va	View angle in radians.
