Fields and methods

Members of the struct camera_projection_orthographic. Most of what you do with a CGP type goes through the free functions listed below.

Fields

`float left = -1.0f`	Left bound of the view volume before scaling by aspect_ratio, -1 by default.
`float right = 1.0f`	Right bound of the view volume before scaling by aspect_ratio, 1 by default.
`float bottom = -1.0f`	Bottom bound of the view volume, -1 by default.
`float top = 1.0f`	Top bound of the view volume, 1 by default.
`float z_min = -10.0f`	Near bound of the view volume along the viewing direction, -10 by default.
`float z_max = 10.0f`	Far bound of the view volume along the viewing direction, 10 by default.
`float aspect_ratio = 1.0f`	Width/height ratio of the viewport, 1 by default, that multiplies left and right (bottom and top are not scaled).

Methods

`mat4 matrix() const`	Returns the 4x4 OpenGL orthographic projection matrix of the box [leftaspect_ratio, rightaspect_ratio] x [bottom, top] x [z_min, z_max]. src
`mat4 matrix_inverse() const`	Returns the inverse of the orthographic projection matrix (normalized device coordinates to camera space). src
