Method Detail

setCameraOrthographicModel

public void setCameraOrthographicModel(CameraOrthographicModel cameraOrthographicModel)

Set the CameraOrthographicModel

Parameters:

cameraOrthographicModel - The CameraOrthographicModel

getCameraOrthographicModel

public CameraOrthographicModel getCameraOrthographicModel()

Description copied from interface: CameraModel

Returns the CameraOrthographicModel, or null if this is a perspective camera

Specified by:

getCameraOrthographicModel in interface CameraModel

Returns:

The CameraOrthographicModel

setCameraPerspectiveModel

public void setCameraPerspectiveModel(CameraPerspectiveModel cameraPerspectiveModel)

Set the CameraPerspectiveModel

Parameters:

cameraPerspectiveModel - The CameraPerspectiveModel

getCameraPerspectiveModel

public CameraPerspectiveModel getCameraPerspectiveModel()

Description copied from interface: CameraModel

Returns the CameraPerspectiveModel, or null if this is an orthographic camera

Specified by:

getCameraPerspectiveModel in interface CameraModel

Returns:

The CameraPerspectiveModel

computeProjectionMatrix

public float[] computeProjectionMatrix(float[] result,
                                       java.lang.Float aspectRatio)

Description copied from interface: CameraModel

Compute the projection matrix for this camera.

The result will be written to the given array, as a 4x4 matrix in column major order. If the given array is null or does not have a length of 16, then a new array with length 16 will be created and returned.

Specified by:

computeProjectionMatrix in interface CameraModel

Parameters:

result - The result array

aspectRatio - An optional aspect ratio that should be used. If this is null, then the aspect ratio of the camera will be used.

Returns:

The result array

createProjectionMatrixSupplier

public java.util.function.Supplier<float[]> createProjectionMatrixSupplier(java.util.function.DoubleSupplier aspectRatioSupplier)

Description copied from interface: CameraModel

Create the supplier of the projection matrix for this camera model.

The matrix will be provided as a float array with 16 elements, storing the matrix entries in column-major order.

Note: If the type of the camera that this CameraModel was created for is neither "perspective" nor "orthographic", then the supplier will print an error message and return the identity matrix.

Specified by:

createProjectionMatrixSupplier in interface CameraModel

Parameters:

aspectRatioSupplier - The optional supplier for the aspect ratio of the camera. If this is null, then the aspect ratio of the camera will be used.

Returns:

The supplier
