Detailed Description

OpenGL backend implementation of RCore.

Entry point for the OpenGL ES / EGL graphics API. It binds the EGL client API, queries the client-level EGL extensions, and enumerates the rendering devices (RGLDevice), one per DRM node (or a single Wayland device). Obtain it from an RCore via RCore::asGL().

Because the GL backend keeps per-thread EGL contexts and defers destruction of resources created on other threads, it also drives garbage collection through clearGarbage() and freeThread().

Member Function Documentation

mainDevice()

RGLDevice * mainDevice ( ) const

inlinenoexcept

Returns the main rendering device as an RGLDevice.

clientEGLExtensions()

const REGLClientExtensions & clientEGLExtensions ( ) const

inlinenoexcept

Returns the client-level EGL extensions available without a display.

clientEGLProcs()

const REGLClientProcs & clientEGLProcs ( ) const

inlinenoexcept

Returns the client-level EGL function pointers loaded at initialization.

clearGarbage()

void clearGarbage ( )

overridevirtualnoexcept

Releases resources on the calling thread that were queued for destruction.

Frees GL resources (contexts, RGLContextData, etc.) that were destroyed from other threads and could not be freed there because their context was not current.

Implements RCore.

freeThread()

void freeThread ( )

noexcept

Tears down all GL state owned by the calling thread.

Destroys the per-thread EGL/Skia contexts and context data for this thread. Called automatically when a thread terminates; may be invoked explicitly to release early.
