Parameters
- left
Type: System.Single
Minimum x-value of the view volume.
- right
Type: System.Single
Maximum x-value of the view volume.
- bottom
Type: System.Single
Minimum y-value of the view volume.
- top
Type: System.Single
Maximum y-value of the view volume.
- zNearPlane
Type: System.Single
Minimum z-value of the view volume.
- zFarPlane
Type: System.Single
Maximum z-value of the view volume.
- result
Type: Microsoft.Xna.Framework.Matrix%
[OutAttribute] 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 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.
