Parameters
- left
- Type: SystemDouble
The minimum x-value of the view volume at the near view plane. - right
- Type: SystemDouble
The maximum x-value of the view volume at the near view plane. - bottom
- Type: SystemDouble
The minimum y-value of the view volume at the near view plane. - top
- Type: SystemDouble
The maximum y-value of the view volume at the near view plane. - zNear
- Type: SystemDouble
The minimum z-value of the view volume. (Distance of the near view plane.)
- zFar
- Type: SystemDouble
The maximum z-value of the view volume. (Distance of the far view plane.)
Return Value
Type:
Matrix44D
The customized, right-handed, perspective projection matrix.
Exceptions Remarks
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).
Infinite Projections:
zFar can be set to PositiveInfinity to create an
infinite projection where the far clip plane is at infinity.
