This library is intended to be used with OpenGL for CSCI441 at the Colorado
School of Mines.

When building, the library must be compiled and linked against OpenGL and glm.  
Headers thatend in *3.hpp are built for OpenGL 3.0+ and additionally depend 
upon GLEW.

TODO Items
  > Handle vertex and face colors in OFF files

Revision History

v1.8	- 16 Nov 2017
  > Added support for MTL files for Phong Shading and diffuse maps

v1.7	- 16 Nov 2017
  > Added loadBMP() support to TextureUtils.hpp\n
  > Added support for ASCII STL files to modelLoader3.hpp\n
  > Added support for OFF files to modelLoader3.hpp\n
  > Fixed reallocation error if model did not load properly\n
  > Added support for ASCII PLY files to modelLoader3.hpp (as long as first three vertex properties are x/y/z location)\n
  > If PLY file does not contain normal information (we're currently not checking for it), can autogenerate vertex normals\n
  > If OFF file does not contain normal information, can autogenerate vertex normals\n
  > If OBJ file does not contain normal information, can autogenerate vertex normals

v1.6	- 15 Nov 2017
  > Added FramebufferUtils3.hpp to print Framebuffer info\n
  > Fixed off by 1 error for normals/texcoords in modelLoader3.hpp\n
  > Fixed overflow error for modelLoader3.hpp when reading in models with more than 65535 vertices

v1.5.1	- 10 Nov 2017
  > Fixed redefinition errors in teapot3.hpp and objects3.hpp\n
  > Fixed bug in ShaderUtils3.hpp to check if OpenGL is version 4.0+ before querying subroutine uniforms

v1.5	- 06 Nov 2017
  > Added loadTGA method to TextureUtils.hpp\n
  > Commenting added to TextureUtils.hpp\n
  > Converted OpenGLUtils from static non-implementable class to namespace\n
  > Added commenting to ShaderProgram3.hpp

v1.4.1	- 05 Nov 2017
  > Fixed bug in objects3.hpp of internally passing torus parameters in incorrect order

v1.4	- 03 Nov 2017
  > Created ShaderUtils3.hpp and ShaderProgram3.hpp to make working with Shaders easier

v.1.3.1	- 28 Oct 2017
  > Matched internal data types to prevent c++11 narrowing warnings on lab machines

v1.3 	- 26 Oct 2017
  > Modified texture coordinates for cylinder to linear step from 0 to 1 in s instead of following cosine\n
  > Modified texture coordinates for sphere to linear step form 0 to 1 in s & t instead of following sine and cosine\n
  > Fixed bug when disk was not being displayed if consisting of 1 ring\n
  > Fixed bug with Partial Disk not starting at current angle\n
  > Fixed bug with normals on Sphere stacks\n
  > Added modelLoader3.hpp to handle loading and drawing OBJ files\n
  > Added objects3.hpp that allow for solid primitives to be drawn with OpenGL 3.0\n
  > Notes for teapot - the teapot cannot be textured and it is a pure teapot with no bottom\n
  > For a textured teapot, look into using an object model

v1.2	- 25 Sep 2017
  > Fixed error in draw*Disk not completing final slice step\n
  > Added TextureUtils to load in a PPM\n
  > Added MaterialStruct structure to group together Phong properties\n
  > Fixed error in drawSolidDisk() not allowing inner radius to be zero

v1.1.1	- 22 Sep 2017
  > Removed GL_MAX_COLOR_ATTACHMENTS to comply with lab machines

v1.1    - 21 Sep 2017
  > Added OpenGLUtils class to store commonly used helper functions

v1.0.1  - 19 Sep 2017
  > Added documentation\n
  > Added inline definition to functions to prevent duplicate linking errors

v1.0    - 01 Sep 2017
  > Initial release of all OpenGL 3D objects
