Created October 15, 2010 14:59

OpenGL 3.0+ Rendering Example - A complete and fairly minimal example of rendering with shaders

	// Triangle_opengl_3_1
	// A cross platform version of
	// http://www.opengl.org/wiki/Tutorial:_OpenGL_3.1_The_First_Triangle_%28C%2B%2B/Win%29
	// with some code from http://www.lighthouse3d.com/opengl/glsl/index.php?oglexample1
	// and from the book OpenGL Shading Language 3rd Edition, p215-216

dlivingstone / LoadModel-GLTools.cpp

Created October 16, 2010 13:07

An example model loader/viewer for OpenGL core profile. This code uses the GLTools library. Model details on the model format will be available at 3dgamedev.wordpress.com ...

	// loadModelDataTest-GLTools
	// A simple app that loads model data from a custom data format
	// the format is a (relatively) simple one based on how an individual
	// mesh may be saved in a Collada file - currently the easiest way
	// to make models, is with Google Sketchup, export to Collada, then
	// manually hack the data and save.
	//
	// A version of this code which only requires GLEW and freeglut is to
	// follow

dlivingstone / defaultLight.vert

Created October 19, 2010 00:22

A loaddata program for OpenGL that will load and render a model stored in a particular matching format. Example model data and fragment shader available here: http://gist.github.com/629763 . This gist includes the main cpp file and the vertex shader only.

	// Vertex Shader – default light
	// This is based (very closely!) on code extracted from the GLShaderManager provided
	// by Richard Wright for the OpenGL SuperBible, 5th Edition
	// The SuperBible source code is available http://www.starstonesoftware.com/OpenGL/

dlivingstone / blocks.uwsm

Created November 1, 2010 07:17

This sample code will load and display a rotating 3D model. Uses OpenGL and the GLTools library from the OpenGL SuperBible. More details on the UWSM model format used (and sample model data) available at http://3dgamedev.wordpress.com

Created July 6, 2012 22:18

OpenGL demo project: A project that needs lots of fixing and restructuring

	// main.cpp
	// A very basic OpenGL/GLUT application using the deprecated OpenGL 1.x

	// (c) Daniel Livingstone, 2012

	// The structure of this program is typical of many simple OpenGL demonstration
	// programs, but is unsuitable for larger projects: The very basic structure
	// is useful when learning OpenGL, but very poor for building large, complex

GED: SDL base code. Requires glew, SDL and SDL_ttf. This base project code is in need of substantial re-writing and improvement - see comments for more details. The MavenPro font required is a free Google Webfont.

	// Game Engine Design - SDL base code
	// This sample project has a complete lack of OO design and makes use of
	// a very large number of global variables. What it does do, is demonstrate
	// use of SDL for window/event management with OpenGL for graphics rendering
	// This project requires the following 3rd party libraries:
	// - glew (GL extension wrangler, for access to OpenGL past 1.1 on Windows)
	// - SDL (base libraries)
	// - SDL_ttf (to render text to a surface/texture for display in OpenGL)
	//
	// There are MANY ways to improve this code, some of which are identified in
