This library is still in beta, you can expect some bugs...

IF YOUR 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

Love3D Library.zip Current Version : 0.3.0 [The Light Update]

Lighting Demo

Instructions

1. Unzip the .zip file
2. If you are using this, put the Love3D.lua in your .love file
3. On the outside of any function in main.lua add :

require "Love3D"

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

love3D.load(fl, vpX, vpY)

1. (Note : FL means Focal Length. This value is usually 250. vp means Vanishing Point) And your done! Just call the functions and your ready to go!
