When you take stereoscopic images, You worry because there are many things. 
This tool calculates the basic parameter of it.
Basic parameters are…


1. Stereobase or Interocular

2. Focal length of a lens

3. Distance to the nearest object

4. Distance to the furthest object or background

5. Parallax


These values are closely related respectively.


A thing important by another one is a size of the display or screen.


This tool calculates parallax value on it with aspect ratio that you want.



6.Screen Size when you show or see it

7.Aspect rate



When the thing you want to take a picture of is already decided, the optimal parameters can be tried from the size and distance etc.



And new features, several values are displayed on upper area.
The vertical and horizontal Fov angle at the specified focal length.
The size of height and width at both point of Near and Far.



8.h,w:

Fov: The Fov angle of vertical, horizontal and diagonal at the focal length

Size: The area size of height and width at Near and Far point
