This sounds pretty great.<p>This technique would be really powerful if the worker thread could pass a buffer of the rendered results off to the main thread efficiently for use by the main thread. For example, a game has a worker thread to refine lightmaps while the main thread uses those lightmaps for rendering the game (similar to <a href="http:&#x2F;&#x2F;madebyevan.com&#x2F;shaders&#x2F;lightmap&#x2F;" rel="nofollow">http:&#x2F;&#x2F;madebyevan.com&#x2F;shaders&#x2F;lightmap&#x2F;</a>). Does anyone know if this is possible?<p>Also, what does this mean for GPU use on the worker? Can heavy GPU use in the worker still lock up the GPU and impact the GPU use of the main thread and the windowing system in the OS?
