Syntax

public static Matrix CreateOrthographic (
         float width,
         float height,
         float zNearPlane,
         float zFarPlane
)

Parameters

  • width
    Width of the view volume.
  • height
    Height of the view volume.
  • zNearPlane
    Minimum z-value of the view volume.
  • zFarPlane
    Maximum z-value of the view volume.

Return Value

The projection matrix.

Remarks

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 coordinate ranging from 0 to 1.

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