nCine::RenderCommandPool class
#include <nCine/Graphics/RenderCommandPool.h>

Pool of reusable render commands.

Keeps allocated RenderCommand instances alive between frames so they can be recycled instead of reallocated. Commands move from the free pool to the used pool when handed out, and Reset() returns them all to the free pool at the end of a frame.
