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]

Lighting Demo

Ambient Lighting Demo

Backface Culling Demo

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 :

• Then on the INSIDE of love.load(), near the end of the function, add :

• (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.

• And you're done!
