Matrix.CreateOrthographicOffCenter Method (Single, Single, Single, Single, Single, Single, Matrix)

Builds a customized, orthogonal projection matrix.

Namespace: Microsoft.Xna.Framework
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

public static void CreateOrthographicOffCenter (
         float left,
         float right,
         float bottom,
         float top,
         float zNearPlane,
         float zFarPlane,
         out Matrix result
)

Parameters

left
Minimum x-value of the view volume.
right
Maximum x-value of the view volume.
bottom
Minimum y-value of the view volume.
top
Maximum y-value of the view volume.
zNearPlane
Minimum z-value of the view volume.
zFarPlane
Maximum z-value of the view volume.
result
[OutAttribute] 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.
