All objects in a 3D Animation are defined with respect to the Default Lights and Cameras frame. This frame coincides with the top Reference Frame. When you start up a 3D animation 5 default cameras are available showing several views of the origin of this frame.
Two cameras show the Default Lights and Cameras frame from a position of x = 5, y = 5 and z = 10. The cameras are pointed to the center of origin of the frame. The Camera Looking At Origin will keep looking at the origin, even if its position is changed. The Perspective Camera will not keep looking at the origin but keep its original orientation when its position is changed.
The Camera Looking At Origin and Perspective Camera.
Three Front cameras are positioned on top of each of the axes of the Default Lights and Cameras frame. The front cameras do not show perspective. I.e. they can be used for 2D-Animation.
|•||Plane Distance: A camera only shows objects that lie between a front plane and a back plane. You can set the distance of these planes (seen from the camera).|
|•||Projection: You can show all objects in perspective (objects further away look smaller) or Orthographic (objects further away are shown equally large). You can choose to show right hand frames or left-hand frames.|
|•||Use the slider bar to set the Zooming.|
|•||When you enable the Look at Position, the camera will always look at a specific position, regardless the position of the camera itself|
|•||You can make the look at position static or connect it to variables of your model.|
|•||Use the Always Look up Vector to let the camera have a fixed angle of view.|
