Return Value

The projection matrix.

Projection space refers to the space after applying projection transformation from view space. After the projection transformation, visible content has x and y coordinates ranging from -1 to 1, and z coordinates ranging from 0 to 1.

Unlike perspective projection, in orthographic projection there is no perspective foreshortening.

The viewable area of this orthographic projection extends from left to right on the x-axis, bottom to top on the y-axis, and zNearPlane to zFarPlane on the z-axis. These values are relative to the position and x, y, and z-axes of the view.

To obtain the viewable area (in world space) of a scene, create a BoundingFrustum and pass the combined view and projection matrix to the constructor.
