 Started work on a Garmin G5 panel to work with X-Plane 11.
+===== Creating a 3D Panel =====
+It took a while to create a 3D Panel. The documentation for the X-Plane, although long, doesn't exactly specify what is needed. Trying to capture it here:
+==== C++ Impacts ====
+I created a DLL according to an example. Inside, it has these 5 functions which must be implemented:
+<code c++>
+PLUGIN_API int XPluginStart(
+	char *		outName,
+	char *		outSig,
+	char *		outDesc)
+PLUGIN_API void	XPluginStop(void)
+PLUGIN_API void XPluginDisable(void) { }
+PLUGIN_API int  XPluginEnable(void) { return 1; }
+PLUGIN_API void XPluginReceiveMessage(XPLMPluginID inFrom, int inMsg, void * inParam) { }
+</code>
+Within XPluginStart is this initialization: ''XPLMCreateWindow_t params;''
+params is a struct with various pointers, mostly to mouse, clicks, keyboard listening functions which must be implemented, even with nothing.
+Then I call this:
+<code c++>
+XPLMRegisterDrawCallback(&callbackContent, xplm_Phase_Gauges, 1, &callbackLineRefCon);
+</code>
+where ''callbackContent'' is a pointer to a function to be called for every draw. This calls my Garmin G5 drawing code.
+==== Requirements to draw and make a 3D Instruments ====
+However, it doesn't call this unless
+  * the Panel_Fighter.png file is the texture file for the Cockpit Object.
+  * The Cockpit Object is indicated as **Int Cockpit** in Plane Maker
+  * There is something (for me, the G5 screen) that is mapped to a texture connected to that Panel_Fighter.png
+  * The Checkbox "Part Of Cockpit Panel" needs to be checked in Texture -> XPlane -> Cockpit Panel -> Part Of Cockpit Panel. Not sure how the ''Cockpit Region selection'' affects this.
