PerspectiveCamera API looks like this:
PerspectiveCamera( fov, aspect, near, far )
fov is the vertical field-of-view in degrees,
aspect is the aspect ratio, and
far are the distances to the near and far clip-planes, respectively.
I propose that the
OrthographicCamera API be changed to:
OrthographicCamera( height, aspect, near, far )
height is the vertical height of the orthographic frustum in world units, and the remaining parameters are the same as those for the
An alternate API is:
OrthographicCamera( width, height, near, far )
Either of these API changes imply that the orthographic frustum is symmetric around the z-axis. I do not believe this is a limiting constraint, but I am open to being convinced otherwise.
