							|  | *   raylib [shaders] example - Apply a shader to a 3d model | 
						
						
							|  | * | 
						
						
							|  | *   NOTE: This example requires raylib OpenGL 3.3 or ES2 versions for shaders support, | 
						
						
							|  | *         OpenGL 1.1 does not support shaders, recompile raylib to OpenGL 3.3 version. | 
						
						
							|  | * | 
						
						
							|  | *   NOTE: Shaders used in this example are #version 330 (OpenGL 3.3), to test this example | 
						
						
							|  | *         on OpenGL ES 2.0 platforms (Android, Raspberry Pi, HTML5), use #version 100 shaders | 
						
						
							|  | *         raylib comes with shaders ready for both versions, check raylib/shaders install folder | 
						
						
							|  | * | 
						
						
							|  | *   This example has been created using raylib 1.3 (www.raylib.com) |
