Hi guys,
I’m currently working on a VR app based on Google VR SDK. The VR object has two cameras (left eye and right eye). But the problem I realized is that the two cameras are rendered in sequence, which means the left eye camera calls OnPreCull(), OnPostRender(), etc., and then the right eye calls those functions afterward.
So here’s my question: is it possible to make these two cameras render in parallel? So that they can start the same time and finish almost the same time.
If this is possible, will I benefit from this operation? Let’s say currently the left eye camera takes 1ms to render, and then the right eye takes another 1ms, so it is totally 2ms for the VR camera to render. If I can make them render in parallel, can I finish all renderings in 1ms?
Thank you very much!
