Remarks
Angles to the right and to the top from the center are positive, while angles to the left and to the bottom are negative. To define a symmetric field of view, set AngleLeft = -AngleRight and AngleDown = -AngleUp. All angle values are defined in radians and have to be in range (-PI/2; PI/2), with AngleLeft less than AngleRight and AngleDown less than AngleUp or the field of view will be regarded as invalid. Respective functions will yield a InvalidParam error if the field of view is invalid.
Fields
| AngleDown |
/ Maximum view angle in radians to the bottom of the camera view (typically negative) |
| AngleLeft |
Maximum view angle in radians to the left of the camera view (typically negative) |
| AngleRight |
Maximum view angle in radians to the right of the camera view |
| AngleUp |
Maximum view angle in radians to the top of the camera view |
Methods
| FromProjectionMatrix(Matrix4x4) |
Converts the part of the given projection matrix which governs the field of view to the generic field of view representation used here. |
| ToProjectionMatrix(Single, Single, DepthConvention, Matrix4x4) |
Converts this FOV to a perspective projection matrix. |
