nCine::RenderStatistics class

#include <nCine/Graphics/RenderStatistics.h>

Gathers statistics about the rendering subsystem.

Accumulates per-frame counters for render commands, buffers, textures, custom VBOs/IBOs, culled nodes, the VAO pool and the command pool. The various rendering classes are friends so they can feed it data; only compiled when profiling is enabled.

Public types

class Commands

Counters for render commands of a single type or aggregated across all types.

class Buffers

Counters for the managed buffers of a single type.

class Textures

Counters for textures and their total video memory usage.

class CustomBuffers

Counters for custom VBOs or IBOs and their total memory usage.

class VaoPool

Counters for the VAO pool size, capacity, reuses and bindings.

class CommandPool

Counters for the render command pool used/free sizes and retrievals.
