Parameters

left

Type: SystemSingle
The minimum x-value of the view volume.

right

Type: SystemSingle
The maximum x-value of the view volume.

bottom

Type: SystemSingle
The minimum y-value of the view volume.

top

Type: SystemSingle
The maximum y-value of the view volume.

zNear

Type: SystemSingle
The minimum z-value of the view volume. (Distance of the near view plane.)

zFar

Type: SystemSingle
The maximum z-value of the view volume. (Distance of the far view plane.)

Return Value

This method is available only in the XNA-compatible build of the DigitalRune.Mathematics.dll.

In contrast to all preceding coordinate spaces (model space, world space, view space) the projection space is left-handed! This is necessary because DirectX uses a left-handed clip space.

In the projection space the x and y-coordinates range from −1 to 1, and the z-coordinates range from 0 (near) to 1 (far).
