Functions

bindAPI

  • bindAPI(api: number): void

createContext

  • createContext(major: number, minor: number): Context

  • Expose eglCreateContext. Note this automatically uses eglGetDisplay(EGL_DEFAULT_DISPLAY) for display. The config is auto hard-coded for now and requests:

    EGL_RED_SIZE, 8,
EGL_GREEN_SIZE, 8,
EGL_BLUE_SIZE, 8,
EGL_ALPHA_SIZE, 8,
EGL_DEPTH_SIZE, 24,
EGL_STENCIL_SIZE, 8,
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES3_BIT_KHR,

    Parameters

    • major: number
    • minor: number

    Returns Context

destroyContext

  • destroyContext(ctx: Context): void

  • Expose eglDestroyContext. Note this automatically uses eglGetDisplay(EGL_DEFAULT_DISPLAY) for display.

    Parameters

    Returns void

initialize

  • initialize(major: number, minor: number): [number, number]

  • Expose eglInitialize. Note this automatically uses eglGetDisplay(EGL_DEFAULT_DISPLAY) for display.

    Parameters

    • major: number

      requested major version

    • minor: number

      requested minor version

    Returns [number, number]

    actual major/minor versions.

makeCurrent

  • Expose eglMakeCurrent.

    Parameters

    • draw: Surface | null

      optional surface for draw commands

    • read: Surface | null

      optional surface for read commands

    • ctx: Context

      context to use for commands.

    Returns void

releaseThread

  • releaseThread(): void

swapBuffers

  • swapBuffers(surface: Surface): void

  • Expose eglSwapBuffers. Note this automatically uses eglGetDisplay(EGL_DEFAULT_DISPLAY) for display.

    Parameters

    Returns void

terminate

  • terminate(): void
