Property Detail
keyproperty
key:String

Key string of a shader. This key is used to cache Program3D objects, when the same shader is used several times. This key must be unique for every shader program you write. So this means if the AGAL changes you must change the key accordingly.


Implementation
    public function get key():String
    public function set key(value:String):void
paramsproperty 
params:ShaderParameters

Returns the shader parameters.


Implementation
    public function get params():ShaderParameters
