* rlgl v4.0 - OpenGL abstraction layer
|

* rlgl v4.0
|
||||
*
|
||||
* 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...).
|
||||
* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0)
|
||||
* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
|
||||
*
|
||||
* When chosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
|
||||
* initialized on rlglInit() to accumulate vertex data.
|
||||
*
|
||||
* When an internal state change is required all the stored vertex data is renderer in batch,
|
||||
* additioanlly, rlDrawRenderBatchActive() could be called to force flushing of the batch.
|
||||
*
|
||||
* Some additional resources are also loaded for convenience, here the complete list:
|
||||
* - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
|
||||
* - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
|
||||
* - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
|
||||
*
|
||||
* Internal buffer (and additional resources) must be manually unloaded calling rlglClose().
|
||||
*
|
||||
* 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:
|
||||
* rlglInit() - Initialize internal buffers and auxiliary resources
|
||||
* rlglClose() - De-initialize internal buffers data and other auxiliar resources
