This library is still incomplete, you can expect some bugs...

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 : 0.2.7

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 :

love.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!

Functions

• love3D.load. Loads the library, must be called in the love.load function

• love3D.calculatePointPosition. Calculates point position by transforming the 3D coordinates to 2D

• love3D.graphics.quad. Draws a quadrilateral

• love3D.graphics.triangle. Draws a triangle

• love3D.graphics.lineSegment2D. Draws a 2D line segmentin 3D space

• love3D.graphics.draw2D. Draws a 2D image in 3D space

• love3D.func.rotateX/Y/Z. Rotates a point in a chosen center point

• love3D.func.checkDistCollision. Checks if two circular objects in 3D space are colliding

• love3D.func.getAvgZTriangle/Quad. Finds the average Z of a triangle/quad

• love3D.func.zSortTriangle/Quad. Sorts a triangle/quad

• love3D.func.zSortPoint. Sorts a table of points

Possible uses

• Spinning cube for menu screens

• A more accurate Parallax Scrolling
