Enum DirectRenderingGLView.BackendMode

Enumeration for backend mode

public enum DirectRenderingGLView.BackendMode

Name	Description
DirectRendering	DirectRendering mode executes GL code within DALi graphics pipeline but creates isolated context hence it doesn't alter any DALi rendering state. When Renderer is about to be drawn, the callback will be executed and the custom code "injected" into the pipeline. This allows rendering directly to the surface rather than offscreen.
DirectRenderingThread	DirectRenderingThread mode executes GL code on separate thread and then blits the result within DALi graphics commands stream. The mode is logically compatible with the EglImageOffscreenRendering.
EglImageOffscreenRendering	EglImageOffscreenRendering mode executes GL code in own thread and renders to the offscreen NativeImage (EGL) buffer. This backend will render in parallel but has higher memory footprint and may suffer performance issues due to using EGL image.
UnsafeDirectRendering	UnsafeDirectRendering mode executes GL code within DALi graphics pipeline WITHOUT isolating the GL context so should be used with caution! The custom rendering code is executed within current window context and may alter the GL state. This mode is considered unsafe and should be used only when drawing on main GL context is necessary! When Renderer is about to be drawn, the callback will be executed and the custom code "injected" into the pipeline. This allows rendering directly to the surface rather than offscreen.
