NAME

SDL::Tutorial::3DWorld - Create a 3D world from scratch with SDL and OpenGL

DESCRIPTION

This tutorial is intended to demonstrate the creation of a trivial but relatively usable "3D Game Engine".

The demonstration code provided implements the four main elements of a basic three-dimensional game world.

  • A static landscape in which events will occur.

  • A light source to illuminate the world.

  • A collection of N objects which move around independantly inside the world.

  • A user-controlled mobile camera through which the world is viewed

Each element of the game world is encapsulated inside a standalone class.

This lets you see which parts of the Open GL operations are used to work with each element of the game world, and provides a starting point from which you can start to make your own simple game-specific engines.

METHODS

new

The new constructor sets up the model for the 3D World, but does not initiate or start the game itself.

It does not current take any parameters.

camera

The camera method returns the currently active camera for the world.

Provided as a convenience for world objects that need to know where the camera is (such as the skybox).

sdl

The sdl method returns the master SDLx::App object for the world.

run

The run method is used to run the game. It takes care of all stages of the game including initialisation and shutdown operations at the start and end of the game.

current

The current method can be used by any arbitrary world element to get access to the world while it is running.
