int64 RE_TimerQuery::getElapsedTimeNS ( RE_Render * r )

inline

Fetch elapsed render time between begin/end in nanoseconds. Returns the elapsed time in nanoseconds. If this extension is not supported, it will always return 0 and assert. Calling this without previously calling begin/end, or inside begin/end, will also assert.

int64 RE_TimerQuery::getTimeStampNS ( RE_Render * r )

inline

Fetch the timestamp recorded by recordTimestamp()

Definition at line 46 of file RE_TimerQuery.h.

bool RE_TimerQuery::recordTimestamp ( RE_Render * r )

inline

Alternate query - request the GPU timestamp. This is useful because timer queries cannot be nested, so higher level intervals can be computed by differencing 2 timestamps. RE_GPUTimer does this.
