If you want to make Cyberix3D a desktop app, there is an easier way instead of learning Urho3D!!!
First, you have the source of Cyberix3D, export it as an .SWF file.
and then go here and then convert the .swf file to .exe!
swftools.sourceforge.net/swf-to-exe.html
And taadaah! You have Cyberix3D as an exe file! Everytime you want to update it, modify the .swf file (and convert it to .exe) and then just replace the original exe file with the new one!
