Most of the examples already working! Only some of them still fail, mostly related to data arrays...

-- raylib [shaders] example - Apply a postprocessing shader to a scene
|
|
--
|
|
-- 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 1.6 (www.raylib.com)
|
|
-- raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
