IF YOU'RE LOOKING FOR ANOTHER LIBRARY OF THE SAME NAME SEE : L3D Library
This library allows you to simulate pseudo-3D, although you can model some basic 3D polyhedrons with the 3D triangles. There are also other functions too.

Download
The Love3D Library.zip Current Version : 0.3.2 [Backface Update]
Instructions
- Unzip the .zip file
- If you are using this, put the Love3D.lua in your .love file
- On the outside of any function in main.lua add :
require "Love3D"
- Then on the INSIDE of love.load(), near the end of the function, add :
love3D.load(fl, vpX, vpY)
- (Note : FL means Focal Length. This value is usually 250. vp means Vanishing Point) And you're done! Just call the functions and you're ready to go!
How to load additional extensions
- Put yourExtension.lua in your love file
- Love3D.lua will automatically require yourExtension.lua when it exists. So just load it inside love.load() AFTER loading Love3D.
love3D.extensionName.load()
- And you're done!
