+form of _MEF_ (**M**esh **E**xternal **F**ile).
+- [IGI Camera View](https://www.researchgate.net/figure/Definition-of-pitch-roll-and-yaw-angle-for-camera-state-estimation_fig15_273225757) - IGI use game Camera called [Viewport](https://en.wikipedia.org/wiki/Viewport) to display the game.

+## Editor components.
+Editor has several components which it needs in order to work fully to its functionality.
+- Server : Located at [OrgFree](http://igiresearchdevelopers.orgfree.com/) which contains Mission files and Resources like Weapon/A.I images for editor.
+- Database : Located at Github Gist private repo contains privacy information like _I.P,Mac Address_ and _Key_ for Editor.
+- Internal DLL : Located at [IGI-Internals](https://github.com/IGI-Research-Devs/IGI_Internal) is used to call IGI Game internal native methods.
+- QEditor - Located at path `C:\Users\my_username\AppData\Roaming\QEditor`  This is appdata file comes pre-installed with any version of editor and can be downloaded from here [QEditor Full Version](https://cutt.ly/p1ASiQX).</br>

+## Editor Working flow.
+Editor most of the time just compiles the script file _QSC_ called _Q_ script source into _QVM_ called _Q_ virtual machine and Restart the level in order to see the affected changes. 
+Here is workflow mentioned.
+1. Get game level and select proper source file of level located at `QEditor\QFiles\IGI_QSC\missions\location0\level`.</br>
+2. Updates the script file with new script depends upon logic Add/Update/Delete commands.</br>
+**Internal compiler**</br>
+3. Copies script file from Editor `C:\IGI-Editor` to `D:\IGI\` and compiles them to binary _QVM_ file and moves them to proper destination.</br>
+**External compiler**</br>
+3. Copies script file from Editor `C:\IGI-Editor` to `QEditor\QCompiler\Compile\input` and compiles them to binary _QVM_ file and convert compiled QVM v7 (IGI 2) to QVM v5 (IGI 1) using _DConv_ tool and moves them to proper destination.</br>
+4. Restart the level and see the changes.</br>
