Method Detail
calcNyARMatrixRotations()method
public static function calcNyARMatrixRotations(mat:NyARDoubleMatrix34, bInDegrees:Boolean = true):Vector3D

Calculate rotation around X, Y, and Z axes, and return stored in a Vector3D instance. NOTE: does not account for scale, as FLARToolkit matrices always scale equally in all three dimensons.

Parameters

mat:NyARDoubleMatrix34
 
bInDegrees:Boolean (default = true)

Returns
Vector3D
calcNyARMatrixScales()method 
public static function calcNyARMatrixScales(mat:NyARDoubleMatrix34):Vector3D

Calculate scale in X, Y, and Z dimensions, and return stored in a Vector3D instance. NOTE: FLARToolkit matrices should always scale equally in all three dimensions, so this method is not likely to be useful. but, it's here now, so here it stays.

Parameters

mat:NyARDoubleMatrix34

Returns
Vector3D
calcProjectionMatrix_Alternativa()method 
public static function calcProjectionMatrix_Alternativa(cameraParams:FLARParam, viewportSize:Rectangle):Matrix3D
