1. A method of determining the impact of objects referenced or rendered by an application executing on a computing device, comprising: (a) intercepting a function call to a graphics or audio application programming interface (API) issued by the application, wherein the interception is performed by an interception component that is not part of the application or the graphics or audio API or execution of which does not require compilation of the application, wherein the intercepting a function call occurs prior to the function call being passed to the API; (b) determining if an object referenced or rendered by the intercepted function call is an object of interest, wherein the determining is performed by an object measurement component that is not part of the application or the graphics or audio API or execution of which does not require compilation of the application; and (c) collecting attribute information relating to the object if the object is determined to be an object of interest, wherein the collecting is performed by the object measurement component.
