        Egl helper method, create object of EGLBase10 or EGLBase14 depending on your environmentmaxClientVersion=3, No stencil buffer.

      • createFrom

         static EGLBase createFrom(EGLBase.IContext sharedContext, boolean withDepthBuffer, int stencilBits, boolean isRecordable)

        Egl helper method, create object of EGLBase10 or EGLBase14 depending on your environmentmaxClientVersion=3

      • createFrom

         static EGLBase createFrom(EGLBase.IContext sharedContext, int maxClientVersion, boolean withDepthBuffer, int stencilBits, boolean isRecordable)

        Egl helper method, create object of EGLBase10 or EGLBase14 depending on your environment

        Parameters:
        withDepthBuffer - If true, use 16-bit depth buffer, if false, no depth buffer
        stencilBits - If it is less than or equal to 0, no stencil buffer

      • release

         abstract void release()

        Destroy related resources

      • getGlVersion

         abstract int getGlVersion()

        Get version of GLES

      • createFromSurface

         abstract EGLBase.IEglSurface createFromSurface(Object nativeWindow)

        Create EglSurface from the specified Surface.Return EglSurface that eglMakeCurrent method is already invoked

        Parameters:
        nativeWindow - Surface/SurfaceTexture/SurfaceHolder

      • createOffscreen

         abstract EGLBase.IEglSurface createOffscreen(int width, int height)

        Create off-screen EglSurface from the specified sizeReturn EglSurface that eglMakeCurrent method is already invoked

        Parameters:
        width - size of PBuffer offscreen (no less than 0)
        height - size of PBuffer offscreen (no less than 0)

      • makeDefault

         abstract void makeDefault()

        Release assignment between the EGL rendering context and thread

      • sync

         abstract void sync()

        Invoke eglWaitGL and eglWaitNative

        eglWaitGL: Complete GL execution prior to subsequent native rendering calls. The same result can be achieved using glFinish.eglWaitNative: Complete native execution prior to subsequent GL rendering calls
