Properties
FarPlane
Gets the far plane distance, or when there is none.
public float FarPlane { get; }Property Value
Remarks
See for where these come out of the matrix.
NearPlane
Gets the distance to the near plane this view was projected with.
public float NearPlane { get; }Property Value
Remarks
Recovered from the projection rather than carried as a field, so it costs nothing in the layout this class is marshalled to the GPU with. The reverse Z form
builds hasM33 = near / (far - near) andM43 = near * far / (far - near), which inverts to this exactly and collapses to plain M43 when the far plane is infinite.
