DETAILED DESCRIPTION
The following description is made for the purpose of illustrating the general principles of one or more embodiments and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations. Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.
One or more embodiments generally relate to interfacing a native physics engine. In one embodiment, access to a native physics engine is embedded within a browser engine. In one embodiment, bindings are provided for supporting a plurality of application classes from the browser engine to the native physics engine and a Javascript engine.
HTML5 is highly portable, familiar to an extremely large developer community, enables easy integration with web services, and is used for next generation platforms, such as Tizen, ChromeOS and Windows 8. Developers frequently cite application performance as a concern when considering web-based platforms, which is particularly true for gaming where there are both high compute and high graphics demands. Pure JavaScript implementation can be 2 to 10 times slower than “native” code.
For compute load of gaming applications, much time is spent in the “physics” code involved with object dynamics and physical simulation. One or more embodiments provide enhanced user experience for applications related to gaming, physical simulation, dynamic visual effects and animation, and physical realism in augmented reality applications by providing efficient access to JavaScript APIs, which bind to native efficient and performant implementation of 2D Physics Engine (Box2D). One or more embodiments allow users the access to efficient native implementation as JavaScript APIs for electronic devices (e.g., mobile phone device, tablet computing device, camera device, camcorder device, media device, laptop computing device, personal computing (PC) device, personal digital assistant (PDA) device, television device, etc.).
One or more embodiments provide a JavaScript interface to a native (open source) physics engine. In conjunction with WebGL, one or more embodiments provide web-based platforms for electronic devices with the compute and graphics power required for gaming, by enabling access to a native physics engine through JavaScript APIs.
FIG. 1 is a schematic view of a communications system, in accordance with one embodiment. Communications system 1 may include a communications device that initiates an outgoing communications operation (transmitting device 2) and a communications network 110, which transmitting device 2 may use to initiate and conduct communications operations with other communications devices within communications network 110. For example, communications system 1 may include a communication device that receives the communications operation from the transmitting device 2 (receiving device 3). Although communications system 1 may include multiple transmitting devices 2 and receiving devices 3, only one of each is shown in FIG. 1 to simplify the drawing.
Any suitable circuitry, device, system or combination of these (e.g., a wireless communications infrastructure including communications towers and telecommunications servers) operative to create a communications network may be used to create communications network 110. Communications network 110 may be capable of providing communications using any suitable communications protocol. In some embodiments, communications network 110 may support, for example, traditional telephone lines, cable television, Wi-Fi (e.g., an IEEE 802.11 protocol), Bluetooth®, high frequency systems (e.g., 900 MHz, 2.4 GHz, and 5.6 GHz communication systems), infrared, other relatively localized wireless communication protocol, or any combination thereof. In some embodiments, the communications network 110 may support protocols used by wireless and cellular phones and personal email devices (e.g., a Blackberry®). Such protocols can include, for example, GSM, GSM plus EDGE, CDMA, quadband, and other cellular protocols. In another example, a long range communications protocol can include Wi-Fi and protocols for placing or receiving calls using VOIP, LAN, WAN, or other TCP-IP based communication protocols. The transmitting device 2 and receiving device 3, when located within communications network 110, may communicate over a bidirectional communication path such as path 4, or over two unidirectional communication paths. Both the transmitting device 2 and receiving device 3 may be capable of initiating a communications operation and receiving an initiated communications operation.
The transmitting device 2 and receiving device 3 may include any suitable device for sending and receiving communications operations. For example, the transmitting device 2 and receiving device 3 may include a mobile telephone devices, television systems, cameras, camcorders, a device with audio video capabilities, tablets, and any other device capable of communicating wirelessly (with or without the aid of a wireless-enabling accessory system) or via wired pathways (e.g., using traditional telephone wires). The communications operations may include any suitable form of communications, including for example, voice communications (e.g., telephone calls), data communications (e.g., e-mails, text messages, media messages), video communication, or combinations of these (e.g., video conferences).

In some embodiments, a processor may drive the display and process inputs received from the user interface. The memory and storage may include, for example, cache, Flash memory, ROM, and/or RAM. In some embodiments, memory may be specifically dedicated to storing firmware (e.g., for device applications such as an operating system, user interface functions, and processor functions). In some embodiments, memory may be operative to store information related to other devices with which the electronics device 120 performs communications operations (e.g., saving contact information related to communications operations or storing information related to different media types and media items selected by the user).
In one embodiment, the control circuitry 126 may be operative to perform the operations of one or more applications implemented on the electronics device 120. Any suitable number or type of applications may be implemented.

pseudo IDL file:



module Box2D {



  interface [



  Constructor,



  InterfaceName=b2Class1



  ] WB2Class1 {



  typeA f1(in typeB p1);



  attribute typeC a1;



  };



}



pseudo glue cpp/h file:



class WB2Class1 {



Public:



  //creator



  WB2Class1* create( );



  //functions



  double f1(WB2Class2* p1);



  //attributes



  WB2Class3* a1( ) const;



  void setA1(const WB2Class3* v);



  b2Class1* m_p;



private:



  WB2Class1( );



};



WB2Class1* WB2Class1::create( )



{



  return new WB2Class1( );



}



WB2Class1::WB2Class1( )



{



  m_p = new b2Class1( );



}



double WB2Class1::f1(WB2Class2* p1)



{



  return m_p->f1(p1->m_p);



}



WB2Class3* a1( ) const



{



  return WB2Class3::create(m_p->a1);



}



void setA1(const WB2Class3* v)



{



  m_p->a1 = v->m_p;



}










In one embodiment, an example of pseudo-code for a web application (e.g., FIG. 3, web application 350) comprises the following:















pseudo code in web application:



function test( ) {



  var obj1 = new b2Class1( );

  var obj3 = new b2Class3( );



  var num = obj1.f1(obj2);



  obj1.a1 = obj3;



}










FIG. 6 shows a functional call flow diagram 600, according to an embodiment. In one embodiment, the functional flow starts from the web application 350. In one example, embodiment, with reference to the pseudo-code for the web application listed above, when ‘obj1.f1’ 610 is called, the JavaScript engine 340 (JavascriptCore) triggers a function call JSC::call( ) 620 that calls into a function in the WebCore 301, for example function ‘jsWB2Class1PrototypeFunctionf1’ 630 in the auto-generated component (e.g., from the Box2D bindings generator module 410) through a table (e.g., a hash table, or similar structure) where key “f1” is mapped to this function. In one example, embodiment, the function jsWB2Class1PrototypeFunctionf1 630 then calls the wrapper/glue layer 420 function ‘WB2Class1::f1’ 640, which further calls the native function ‘b2Class1::f1’ 650 from the Box2D native engine 450.
