-* DESCRIPTION:
|
|
|
-*
|
|
|
-* rlgl allows usage of OpenGL 1.1 style functions (rlVertex) that are internally mapped to
|
|
|
-* selected OpenGL version (1.1, 2.1, 3.3 Core, ES 2.0).
|
|
|
+* rlgl is a wrapper for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0) to
|
|
|
+* pseudo-OpenGL 1.1 style functions (rlVertex, rlTranslate, rlRotate...).
|
|
|
*
|
|
|
* When chosing an OpenGL version greater than OpenGL 1.1, rlgl stores vertex data on internal
|
|
|
* VBO buffers (and VAOs if available). It requires calling 3 functions:
