Map window coordinates to object coordinates.

[Android.Runtime.Register("gluUnProject", "(FFF[FI[FI[II[FI)I", "")]
public static int GluUnProject (float winX, float winY, float winZ, float[]? model, int modelOffset, float[]? project, int projectOffset, int[]? view, int viewOffset, float[]? obj, int objOffset);

[<Android.Runtime.Register("gluUnProject", "(FFF[FI[FI[II[FI)I", "")>]
static member GluUnProject : single * single * single * single[] * int * single[] * int * int[] * int * single[] * int -> int

Parameters

winX: Single

window coordinates X

winY: Single

window coordinates Y

winZ: Single

window coordinates Z

model: Single[]

the current modelview matrix

modelOffset: Int32

the offset into the model array where the modelview maxtrix data starts.

project: Single[]

the current projection matrix

projectOffset: Int32

the offset into the project array where the project matrix data starts.

view: Int32[]

the current view, {x, y, width, height}

viewOffset: Int32

the offset into the view array where the view vector data starts.

obj: Single[]

the output vector {objX, objY, objZ, objW}, that returns the computed homogeneous object coordinates.

objOffset: Int32

the offset into the obj array where the obj vector data starts.

Returns

Int32

A return value of GL10.GL_TRUE indicates success, a return value of GL10.GL_FALSE indicates failure.

Attributes: RegisterAttribute

Remarks

Map window coordinates to object coordinates. gluUnProject maps the specified window coordinates into object coordinates using model, proj, and view. The result is stored in obj.

Note that you can use the OES_matrix_get extension, if present, to get the current modelView and projection matrices.
