Projections.

Variants

Ortho

Orthographic projection.

Fields of Ortho

width: S	The width of orthographic window.

near: S	The near clip plane.
far: S	The far clip plane.

Perspective

Perspective projection.

Fields of Perspective

fovy: Rad<S>	Field of view in vertical.
aspect: S	The aspect of width / height.
near: S	The near clip plane.
far: S	The far clip plane.
