I think you misunderstand how the projection matrix works....

setProjectionMatrixAsPerspective is defined with the parameters (vFov, aspect, 
near, far)

vFov sets the vertical field of view of the perspective meaning you will have a 
wider viewing angle the larger the value gets.

aspectRatio is used to determine the horizontal FOV

near defines the near clipping plane

far defines the far clipping plane

Increasing the vFOV will make items in the scene appear shorter away but their 
distance from the camera will remain unchanged. 

Cheers,
Steven
