virtual ~BaseCamera ()
 
virtual void Capture (Image &_image)
 Renders a new frame and writes the results to the given image. This is a convenience function for single-camera scenes. It wraps the pre-render, render, post-render, and get-image calls into a single function. This should be used in applications with multiple cameras or multiple consumers of a single camera's images. More...
 
virtual common::ConnectionPtr ConnectNewImageFrame (Camera::NewFrameListener _listener)
 Subscribes a new listener to this camera's new frame event. More...
 
virtual void Copy (Image &_image) const
 Writes the last rendered image to the given image buffer. This function can be called multiple times after PostRender has been called, without rendering the scene again. Calling this function before a single image has been rendered will have undefined behavior. More...
 
virtual Image CreateImage () const
 Created an empty image buffer for capturing images. The resulting image will have sufficient memory allocated for subsequent calls to this camera's Capture function. However, any changes to this cameras properties may invalidate the condition. More...
 
virtual double FarClipPlane () const
 Get the camera's far clipping plane distance. More...
 
virtual math::Vector3d FollowOffset () const
 Get the follow offset vector in the frame specified at the time the follow target is set. More...
 
virtual double FollowPGain () const
 Get the camera follow movement P gain. More...
 
virtual NodePtr FollowTarget () const
 Get the target node being followed. More...
 
virtual math::Angle HFOV () const
 Get the camera's horizontal field-of-view. More...
 
virtual PixelFormat ImageFormat () const
 Get the image pixel format. If the image pixel format has not been set with a valid value, PF_UNKNOWN will be returned. More...
 
virtual unsigned int ImageHeight () const
 Get the image height in pixels. More...
 
virtual unsigned int ImageMemorySize () const
 Get the total image memory size in bytes. More...
 
virtual unsigned int ImageWidth () const
 Get the image width in pixels. More...
 
virtual double NearClipPlane () const
 Get the camera's near clipping plane distance. More...
 
virtual void PostRender ()
 Preforms any necessary final rendering work. Once rendering is complete the camera will alert any listeners of the new frame event. This function should only be called after a call to Render has successfully been executed. More...
 
virtual void PreRender ()
 Prepare this object and any of its children for rendering. This should be called for each object in a scene just before rendering, which can be achieved by a single call to Scene::PreRender. More...
 
virtual bool SaveFrame (const std::string &_name)
 Writes the previously rendered frame to a file. This function can be called multiple times after PostRender has been called, without rendering the scene again. Calling this function before a single image has been rendered will have undefined behavior. More...
 
virtual void SetFollowOffset (const math::Vector3d &_offset)
 Set offset of camera from target node being followed. The offset will be in the frame that is specified at the time the follow target is set. More...
 
virtual void SetFollowPGain (const double _pGain)
 Set follow P Gain. Determines how fast the camera moves to follow the target node. Valid range: [0-1]. More...
 
virtual void SetFollowTarget (const NodePtr &_target, const math::Vector3d &_Offset, const bool _worldFrame)
 Set a node for camera to follow. The camera will automatically update its position to keep itself at the specified offset distance from the target being followed. If null is specified, camera follow is disabled. In contrast to SetTrackTarget, the camera does not change its orientation when following is enabled. More...
 
virtual void SetImageFormat (PixelFormat _format)
 Set the image pixel format. More...
 
virtual void SetImageHeight (const unsigned int _height)
 Set the image height in pixels. More...
 
virtual void SetImageWidth (const unsigned int _width)

virtual void SetTrackPGain (const double _pGain)
 Set track P Gain. Determines how fast the camera rotates to look at the target node. Valid range: [0-1]. More...
 
virtual void SetTrackTarget (const NodePtr &_target, const math::Vector3d &_offset, const bool _worldFrame)
 Set a node for camera to track. The camera will automatically change its orientation to face the target being tracked. If null is specified, tracking is disabled. In contrast to SetFollowTarget the camera does not change its position when tracking is enabled. More...

 Get the track offset vector in the frame specified at the time the track target is set. More...
 
virtual double TrackPGain () const
 Get the camera track rotation P gain. More...
