Form3D - a Free pixel perfect 3d gui
Free Public Domain

This is a free public opensource Blitz3D project. You can derive your own works form it or even help add gui functionality to this. It's 100% free!

[Note]
I currently have no plans to update this code. I want to redo it all. I will leave this code here for learning/idea generating purposes. The way the mesh is created to display the pixel perfect textures I will still use in the same way.

- F3D_Input is not 100% complete. You can edit text, select text position with mouse click, use backspace... but needs more keyboard controls like delete, end, home, etc...
- Added automated mouse graphic


Have fun! :)
