/*******************************************************************************************
*
* raylib [rlgl] example - Oculus minimum sample
*
* NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
* OpenGL 1.1 does not support shaders but it can also be used.
*
* Compile rlgl module using:
* gcc -c rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33 -DRLGL_OCULUS_SUPPORT
*
* NOTE 1: rlgl module requires the following header-only files:
* external/glad.h - OpenGL extensions loader (stripped to only required extensions)
* shader_standard.h - Standard shader for materials and lighting
* shader_distortion.h - Distortion shader for VR
* raymath.h - Vector and matrix math functions
*
* NOTE 2: rlgl requires LibOVR (Oculus PC SDK) to support Oculus Rift CV1
*
* Compile example using:
* gcc -o rlgl_oculus_rift.exe rlgl_oculus_rift.c rlgl.o -L. -lLibOVRRT32_1 -lglfw3 -lopengl32 -lgdi32 -std=c99
*
* NOTE: Example must be linked against LibOVRRT32_1.dll that comes with Oculus Rift runtime.
*
* This example has been created using raylib 1.5 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
