Static Public Attributes

static constexpr size_t UNIFORM_GENERATIONS = 3
 A frame's passes are still queued when the next frame is built, so frames rotate through several uniform sets rather than waiting on the previous one.
 

Detailed Description

Per-window state owned by the render thread.

It is created and destroyed by the SWAPCHAIN_CREATE/RESIZE/DESTROY control commands and touched by no other thread.
