E.B	Hello, Coppercube.exe (http://www.ambiera.com/coppercube/index.html) is a software that allows you to create, among other things, WebGL pages controlled by javascript that are written by the users and passed as argument in (for example) essai.ccbjs (see the following example) to file copperlicht.js (attached file). <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script type="text/javascript" src="copperlicht.js"></script> </head> <body> <div align="center"> <canvas id="3darea" width="640" height="480" style="background-color:#000000"> </canvas> </div> <script type="text/javascript"> <!-- startCopperLichtFromFile('3darea', 'essai.ccbjs', 'Loading $PROGRESS$...'); --> </script> <br/> <div align="center"> <small>Created using the <a href="CopperLicht" name="http://www.ambiera.com/copperlicht/index.html">CopperLicht">http://www.ambiera.com/copperlicht/index.html">CopperLicht JavaScript 3D Engine</a> and the <a href="CopperCube" name="http://www.ambiera.com/coppercube/index.html">CopperCube">http://www.ambiera.com/coppercube/index.html">CopperCube 3D Editor</a></small> </div> </body> </html> I try now to use JS functions of the software in EWB for controllinge WebGL scene from EWB. These JavaScript functions are given in the documentation (http://www.ambiera.com/coppercube/doc/index.html) and are coded in copperlight.js wich is an obsfurcated file. I tried several EWB statement (external) without work. How to write these lines of code? For example, How should I write EWB code for using function startCopperLichtFromFile wich is not obsfurcated in coppercube.js ? For example, How shouldI write EWB code for using function ccbCloneSceneNode(node) wich is obsfurcated in coppercube.js ? Using Windows object ? Regards, Eric. Attachments: copperlicht.js

IOW, it's going to take a while to do. << For example, How should I write EWB code for using function startCopperLichtFromFile wich is not obsfurcated in coppercube.js ? >> I have no idea without tracing through their entire source code. The parameters are easy (all strings), but the return value is an id object instance, which they don't document anywhere. You should contact them and see if they have any documentation that includes the types of the various parameters along with how each object is defined in the API. This is basic API stuff, and just because it's JavaScript doesn't mean that it isn't necessary for proper usage. Google documents all of their APIs with complete type definitions.

E.B	Ok Tim, I asked the developer of CopperCube for help. In addition, you would like to excuse my maybe stupid question, but startCopperLichtFromFile function seems to send nothing back and takes a canvas and 3 strings as arguments . Can you show me how to use this function in EWB? "Tim Young [Elevate Software]" wrote: Eric, << I try now to use JS functions of the software in EWB for controllinge WebGL scene from EWB.

Walter Matte Tactical Business Corporation	From CopperLicht website.... <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <script type="text/javascript" src="copperlichtdata/copperlicht.js"></script> </head> <body> <div align="center"> <canvas id="3darea" width="640" height="480" style="background-color:#000000"> </canvas> </div> <script type="text/javascript"> <!-- startCopperLichtFromFile('3darea', 'copperlichtdata/coppercube.ccbjs'); --> </script> </body> </html> so in EWB unit declare: external function startCopperLichtFromFile(const myelementid: string; const thefilename: string); I only see 2 aguments in the example above... but if there are more... add more..... Be sure to add the external js library to the external code list and copy it into you output folder. Walter E.B wrote: Ok Tim, I asked the developer of CopperCube for help.

E.B	Thanck you Walter. I thinck you forgot one thing : Being sure that the 3DCanvas "3darea" has been created before calling startCopperLichtFromFile(). I tried many things before asking Tim. None of then worked. The last was (after having declared copperlicht.js as external in Project/Option/External, and put essai.ccbjs file in root directory) : ******************************* unit Unit1; interface uses WebCore, WebForms, WebCtrls; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); procedure Form1Create(Sender: TObject); private { Private declarations } public { Public declarations } end; external function ccbGetSceneNodeFromName(s:string):String; external function startCopperLichtFromFile(S1,S2:String); var Form1: TForm1; implementation procedure TForm1.Button1Click(Sender: TObject); begin startCopperLichtFromFile('3darea','essai.ccbjs'); end; end. ***************************** AND essai.html : ***************************** <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script type="text/javascript" src="copperlicht.js"></script> </head> <body> <div align="center"> <canvas id="3darea" width="640" height="480" style="background-color:#000000"> </canvas> </div> <script type="text/javascript"> <!-- startCopperLichtFromFile('3darea', 'essai.ccbjs', 'Loading $PROGRESS$...'); --> </script> <br/> <div align="center"> <small>Created using the <a href="CopperLicht" name="http://www.ambiera.com/copperlicht/index.html">CopperLicht">http://www.ambiera.com/copperlicht/index.html">CopperLicht JavaScript 3D Engine</a> and the <a href="CopperCube" name="http://www.ambiera.com/coppercube/index.html">CopperCube">http://www.ambiera.com/coppercube/index.html">CopperCube 3D Editor</a></small> </div> </body> </html> ******************************* Eric.

Currently, EWB only includes external interfaces for 2D canvas contexts since the 3D context support wasn't widespread yet. Tim Young Elevate Software www.elevatesoft.com

E.B	Tim, Would you like to see my last message ? --> http://www.elevatesoft.com/forums?action=view&category=ewb&id=ewb_general&msg=3951&page=1 Here the entire page is built by Html code in a Tpage. Why do EWB doesn't reproduce the same page ? the command <canvas id="3darea" width="640" height="480" style="background-color:#000000"> creates a standart 2D canvas, exactly the same that is used in Tpaint component.
