SyntaxThe OrthographicProjection type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | OrthographicProjection |
Initializes a new instance of the OrthographicProjection class.
|
Methods| Name | Description | |
|---|---|---|
| Clone |
Creates a new Projection that is a clone (deep copy) of the current instance.
(Inherited from Projection.) |
 | CloneCore |
Makes the instance a clone (deep copy) of the specified
Projection.
(Overrides ProjectionCloneCore(Projection).) |
| ComputeProjection |
Computes the projection matrix.
(Overrides ProjectionComputeProjection.) |
| CreateInstanceCore |
When implemented in a derived class, creates a new instance of the Projection
derived class.
(Overrides ProjectionCreateInstanceCore.) |
| Equals | (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
 | FromMatrix |
Creates an orthographic projection from a 4x4 transformation matrix.
|
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Invalidate |
Invalidates the projection matrix.
(Inherited from Projection.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Set(Matrix44F) |
Sets the orthographic projection from the given projection matrix.
(Overrides ProjectionSet(Matrix44F).) |
| Set(Single, Single) |
Sets a right-handed, orthographic projection with the specified size.
|
| Set(Single, Single, Single, Single) |
Sets a right-handed, orthographic projection with the specified size and depth.
|
| SetOffCenter(Single, Single, Single, Single) |
Sets a customized (off-center), right-handed, orthographic projection.
|
| SetOffCenter(Single, Single, Single, Single, Single, Single) |
Sets a customized (off-center), right-handed, orthographic projection (including depth).
|
| ToMatrix44F |
Converts a projection to a 4x4 transformation matrix.
(Inherited from Projection.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| ToXna |
Converts a projection to a 4x4 transformation matrix (XNA Framework). (Only available in the
XNA-compatible build.)
(Inherited from Projection.) |
Operators| Name | Description | |
|---|---|---|
 | (Matrix44F to OrthographicProjection) |
Converts a 4x4 projection matrix to an orthographic projection.
|
Properties| Name | Description | |
|---|---|---|
 | AspectRatio |
Gets the aspect ratio (width / height) of the view.
(Inherited from Projection.) |
| Bottom |
Gets or sets the minimum y-value of the view volume at the near view-plane.
(Inherited from Projection.) |
| Depth | (Inherited from Projection.) |
| Far |
Gets or sets the distance to the far view plane.
(Inherited from Projection.) |
| FieldOfViewX |
Gets the horizontal field of view in radians.
(Inherited from Projection.) |
| FieldOfViewY |
Gets the vertical field of view in radians.
(Inherited from Projection.) |
| Height |
Gets the height of the view volume at the near view plane.
(Inherited from Projection.) |
| Inverse |
Gets the inverse of the projection matrix.
(Inherited from Projection.) |
| Left |
Gets or sets the minimum x-value of the view volume at the near view-plane.
(Inherited from Projection.) |
| Near |
Gets or sets the distance to the near view plane.
(Inherited from Projection.) |
| Right |
Gets or sets the maximum x-value of the view volume at the near view-plane.
(Inherited from Projection.) |
| Top |
Gets or sets the maximum y-value of the view volume at the near view-plane.
(Inherited from Projection.) |
| ViewVolume |
Gets (or sets) the shape of the view volume (viewing frustum).
(Inherited from Projection.) |
| Width |
Gets the width of the view volume at the near view plane.
(Inherited from Projection.) |
RemarksThe projection can be set in several ways:
- By setting the properties Left, Right, Bottom, Top, Near, and Far.
- By setting assigning a projection matrix using Set(Matrix44F) or the property Inverse.
- By calling on of the following methods: Set(Single, Single), Set(Single, Single, Single, Single), Set(Matrix44F), SetOffCenter(Single, Single, Single, Single), SetOffCenter(Single, Single, Single, Single, Single, Single),
The property ViewVolume defines the bounding shape of the projection which can be used for frustum culling. The shape is updated automatically when the properties of the projection change.
