void Camera::getBoundingBox (  SCENE *    scene )

Gets the bounding box of the scene. Its the smallest cuboid containing all the points of the scene object.

void Camera::loadConfigData (  void    )

Loads config data from file user.ini

void Camera::lookTo (  float    x, float    y, float    z )

Looks to the point defined by 3D coordinates x,y,z Parameters: x  : x coord y  : y coord z  : z coord

void Camera::resetView (    )

Resets the point of view to its initial value defined in user.ini

void Camera::setPerspective (    )

Sets the perspective with the right aspect ratio the width and height of the viewport is taken with the glGetIntegerv (GL_VIEWPORT, viewport) procedure.
