Detailed Description

A timer which uses a cache of values to only update its values every N calls to lap/elapsed. Useful for displaying frame rate.

Constructor & Destructor Documentation

Menge::Vis::SampleTimer::SampleTimer ( int sampleCount )

Constructor.

Parameters

sampleCount The number of repeated calls to lap to cause the timer to report a new, average value.

float Menge::Vis::SampleTimer::lap ( float scale = 1.f )

Reports the average elapsed time of the last N calls to lap.

Parameters

scale The scale of the units to report the elapsed time in. e.g., 1.0 –> seconds, 0.001 –>, 1e-6 –> microseconds.
