* raylib [shaders] example - Apply an shdrOutline to a texture
|
|
*
|
|
* 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.
|
|
*
|
|
* Example originally created with raylib 4.0, last time updated with raylib 4.0
|
|
*
|
|
* Example contributed by Samuel Skiff (@GoldenThumbs) and reviewed by Ramon Santamaria (@raysan5)
|
|
*
|
|
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
|
|
* BSD-like license that allows static linking with closed source software
