* raylib [textures] example - Texture drawing
|
||||
* raylib [shaders] example - texture outline
|
||||
*
|
||||
* This example illustrates how to draw on a blank texture using a shader
|
||||
* Example complexity rating: [★★★☆] 3/4
|
||||
*
|
||||
* This example has been created using raylib 2.0 (www.raylib.com)
|
||||
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
|
||||
* 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 contributed by Michał Ciesielski and reviewed by Ramon Santamaria (@raysan5)
|
||||
* Example originally created with raylib 4.0, last time updated with raylib 4.0
