There are 4 available types of camera. The first type parameter expects one of following values:

• NEsquimo3D.CAMERA_TYPE_FREE
• NEsquimo3D.CAMERA_TYPE_TARGET
• NEsquimo3D.CAMERA_TYPE_PHOTOTARGET
• NEsquimo3D.CAMERA_TYPE_PRESENTATION

You can find more about available camera types and their way of working in Camera chapter.

FOV (Field of view) parameter is related to focal length and determines the size of captured area by camera lens.

            var myCamera1:uint = m_esquimo.CreateCamera(NEsquimo3D.CAMERA_TYPE_FREE, 45);
          

Notice, that "Free camera" jest created with initial angle = [0,0,0] (camera is looking down) unlike while creating in editor where init angle values are [90,0,-90] (camera is positioned horizontally).

Usually the method is called just after CreateCamera method. It is also used to switch active camera among others available in the scene.

            m_esquimo.SetActiveCamera(myCamera1);
          

You can achieve some interesting effects by making transitions of FOV parameter in time.

            (...)
            step = 30;
            m_esquimo.addEventListener(NEsquimo3D.FRAME_RENDERED, m_esquimo_frameRendered);
            (...)
            
            private function m_esquimo_frameRendered(e:Event):void 
            {
              step += 0.5;
              m_esquimo.SetCameraFOV(myCamera1, step);
            }
          

            m_esquimo.SetCameraPosition(myCamera1, 10, 0, 4);
          

            m_esquimo.SetCameraTargetPosition(myCamera1, 0, 4, 0);
          

You need to call this method prior to apllying permanent rotation values. It is commonly used when current angle of the camera is stored in separate variables.

            m_esquimo.ClearCameraRotationMatrix(myCamera1);             
          

To show you the point of using this method compare these two simple examples below:

• 1) camera rotation in case when the angle is stored in separate variable:

                angle = 0;
                m_esquimo.addEventListener(NEsquimo3D.FRAME_RENDERED, m_esquimo_frameRendered);
                (...)

                private function m_esquimo_frameRendered(e:Event):void 
                {
                  angle += 0.1;
                  m_esquimo.ClearCameraRotationMatrix(myCamera1);             
                  m_esquimo.AppendCameraRotationMatrixX(myCamera1, angle);
                  
                }           
              

• 2) camera rotation in case of constant angle increment:

                m_esquimo.addEventListener(NEsquimo3D.FRAME_RENDERED, m_esquimo_frameRendered);
                (...)

                private function m_esquimo_frameRendered(e:Event):void 
                {
                  m_esquimo.ClearCameraRotationMatrix(myCamera1);             
                  m_esquimo.AppendCameraRotationMatrixX(myCamera1, 0.1);
                }           
              

            m_esquimo.SetCameraRoll(myCamera1, 15);
          

The axis that the camera is rotating around is the Z axis of global coordinate system.

from / to parameters specify the range of camera rotation.

multiply parameter tells how fast the camera motion is comparing to speed of mouse motion.

            m_esquimo.SetTargetCameraMouseEventRotateZ(myCamera1, -30, 30, 1);
          

from / to parameters specify the min/max of camera movement towards the target.

multiply parameter tells how fast the camera motion is comparing to speed of mouse motion.

            m_esquimo.SetTargetCameraMouseEventZoom(myCamera1, -1, 5, 0.5);
