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 :
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!

Functions

Love3D 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.isBackFace. Checks if the face is a backface
  • love3D.graphics.quad. Draws a quadrilateral
  • love3D.graphics.triangle. Draws a triangle
  • love3D.graphics.lineSegment2D. Draws a 2D line segment in 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 by their average Z
  • love3D.func.zSortTriangle2. Sorts a triangle triangle by their minimum Z
  • love3D.func.zSortPoint. Sorts a table of points
  • love3D.checkVersion. Checks the current version of Love3D

Light3D Functions

  • love3D.light.load. Loads Light3D.lua
  • love3D.light.set. Sets all the variables
  • love3D.light.setAmbience. Sets the ambient lighting
  • love3D.light.getLightFactor. Gets the light factor (only used by love3D.light.getNewColor)
  • love3D.light.getNewColor. Gets the new color

Possible uses

  • Spinning cube for menu screens
  • A more accurate Parallax Scrolling

Changelog

  • 0.1.x : Added the perspective function
  • 0.2.0 -> 0.2.8 : Added simple perspective functions and graphics functions
  • 0.2.9 : Optimized code, renamed the perspective function
  • 0.3.0 : Added simple lighting, optimized code
  • 0.3.1 : Added ambient lighting, removed the [[Experimental]] tag
  • 0.3.2 : Added Backface culling, added a second zSort function for the triangle, added support for Beetle Debug, added Preset3D
