|
* raylib [shaders] example - shapes textures
|
|
*
|
|
* Example complexity rating: [★★☆☆] 2/4
|
|
*
|
|
* 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
|
|
*
|
|
* Example originally created with raylib 1.7, last time updated with raylib 3.7
|
|
*
|
|
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
|
|
* BSD-like license that allows static linking with closed source software
