Whiteboard Status

Hi, I've many problems with my internet connection (sorry Emil), my internet provider (Free&FT) isn't fast to solve my problems :( So here a quick status mail of the Whiteboard plugin. In 2D objects are not representable with ones simple list of triangles as in 3D The goal is to have a basic model which can adapt to any type of forms: the WhiteboardObject. To simplify, this object has several types: rectangle, circle, curved, image, path…(like in SVG)  Then with the implementation of this object in the protocol Jabber (XEP-0113 + mobil SVG) it's necessary to separate the various types of objects for the generation of code XML: WhiteboardObjectImplJabber adds an method "toXML()" for each type: this methode generate a valid SVG-XML string for each objects. Similar for display, the structure of the class is almost similar to the implementation in Jabber, but here, the goal is different, it  doesn't generate a XML, we want to display an object: thus we have a drawing method (using the Graphics2D context of the GUI) and a contains method for detections (intersections) There are good ideas in SVGSalamander/Gazelle,  but I think that we can use these ideas without having to use these lib by adding my own SVG-display & management  classes : because my objective is to have complete system but with the lightest size possible. Currently, I look for a system (like a plugin system ?) to add easily "modes of drawing" (draw path/draw rect/draw circle….). I am also analyzing: "XEP-0155: Stanza Negotiation Session" if somebody has an opinion to give on this protocol… ;) It will be used for me to authorize the launching of the whiteboard. And if my internet provider wants it, I will be more present the next week ^^ Julien
