PicoCAD Client

Starter kit 3d engine to display PicoCAD models:

• basic FPS controller
• perspective camera
• optimized transform & project pipeline
• global sorting

Note: sample code requires Pico8

Many points are left to the reader:

• efficient culling of non visible objects
• near plane clipping
• collision & anything related to a particular game

How To Use

• Edit model using PicoCAD
• Export model to p8l file
• Edit p8l file to remove comments
• Copy texture image in picocad_player.p8 cart
• Edit Include p8l file in picocad_player.p8. Ex:

#include chunky_tank.p8l

• Create 3d entity in _init with:

  _entities={
    -- initial (x,y,z) position + reference to 3d model  
    -- note: y is up  
    make_3dobject({5,0,5},chunky_tank)
  }

• Change game logic/structure to fit your game!
• Good luck
