Describes the stereoscopic rendering details of an eye.

(int type)

Creates a new set of eye parameters.

()

Returns a matrix that transforms from the camera to the current eye.

()

Returns the field of view for this eye.

(float zNear, float zFar)

Convenience method that returns the perspective projection matrix for this eye.

()

Returns the eye type this object refers to.

Creates a new set of eye parameters.

Returns a matrix that transforms from the camera to the current eye.

This matrix should premultiply the camera matrix.

Assumes a scale of 1 world unit = 1 meter when applying the interpupillary distance. If this not your case, make sure to call android.opengl.Matrix.scaleM on this matrix to correct it.

The transformation includes head tracking rotation, position shift and interpupillary distance shift. Use this if you just want to get an eye view from your normal view.

• A 4x4 column-major representing the transformation from the camera to this eye.

Returns the field of view for this eye.

Use the getFov().toPerspectiveMatrix method to generate the appropriate perspective projection matrix to use.

• The field of view for this eye.

Convenience method that returns the perspective projection matrix for this eye.

Calls getFov().toPerspectiveMatrix to generate the perspective matrix to use.

• A 4x4 column-major matrix representing the perspective projection for this eye.

Whether the projection matrix is stale and should be recomputed.

• true if projection matrix is stale, false otherwise

Returns the eye type this object refers to.

• The current eye as one of the Eye.Type constants.

Returns the viewport for this eye.

• Viewport to use when rendering this eye.

Forces to clean up any cached projection matrices.

Called by the framework when projection parameters change between frames. Should be called if the eye's field of view object returned by getFov() is changed.

Key actions include creating `Eye` objects with a specified type, retrieving the transformation matrix from the camera to the eye via `getEyeView()`, and getting the field of view (`getFov()`). It can also obtain the perspective projection matrix (`getPerspective()`) and viewport (`getViewport()`). The class provides methods to check and set the projection matrix's staleness (`getProjectionChanged()`, `setProjectionChanged()`) and retrieve the eye type (`getType()`).\n"]]
