b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	3 * rlgl v6.0 - A multi-OpenGL abstraction layer with an immediate-mode style API
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	4 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	5 * DESCRIPTION:
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	6 * An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0, ES 3.0)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	7 * that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	8 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	9 * ADDITIONAL NOTES:
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	10 * When choosing an OpenGL backend different than OpenGL 1.1, some internal buffers are
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	11 * initialized on rlglInit() to accumulate vertex data
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	12 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	13 * When an internal state change is required all the stored vertex data is rendered in a batch,
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	14 * additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	15 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	16 * Some resources are also loaded for convenience, here the complete list:
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	17 * - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	18 * - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	19 * - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	20 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	21 * Internal buffer (and resources) must be manually unloaded calling rlglClose()
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	22 *
