Function ortho

Build an orthographic projection matrix with NDC determined at runtime


						
				Mat4!T ortho(T)
				(
				

				  NDC ndc,
				

				  in T l,
				

				  in T r,
				

				  in T b,
				

				  in T t,
				

				  in T n,
				

				  in T f
				

				);

Parameters

Name	Description
ndc	the target NDC
l	X position of the left plane
r	X position of the right plane
b	Y position of the bottom plane
t	Y position of the top plane
n	distance from origin to near plane (in Z-)
f	distance from origin to far plane (in Z-)

Returns

an affine matrix that maps from eye coordinates to NDC.
