Matrix.CreateOrthographicOffCenter Method (Single, Single, Single, Single, Single, Single, Matrix)
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 )
- Minimum x-value of the view volume.
- Maximum x-value of the view volume.
- Minimum y-value of the view volume.
- Maximum y-value of the view volume.
- Minimum z-value of the view volume.
- Maximum z-value of the view volume.
- [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.
