void RE_GPUTimer::begin ( RE_Render * r )

inline

Mark the beginning and end of GPU commands to time Bracket the draw calls to measure with begin and end. Multiple begin/end calls without a reset() will accumulate time.

Definition at line 70 of file RE_TimerQuery.h.

void RE_GPUTimer::destroy ( )

inline

Deletes the queries. init() must be called again.

Definition at line 117 of file RE_TimerQuery.h.

void RE_GPUTimer::end ( RE_Render * r )

inline

Mark the beginning and end of GPU commands to time Bracket the draw calls to measure with begin and end. Multiple begin/end calls without a reset() will accumulate time.

Definition at line 80 of file RE_TimerQuery.h.

int64 RE_GPUTimer::getElapsedTimeNS ( RE_Render * r )

inline

Fetch elapsed render time between begin/end in nanoseconds.

Definition at line 100 of file RE_TimerQuery.h.

bool RE_GPUTimer::hasResult ( ) const

inline

Returns true if a begin/end was performed. Does not mean the result is necessarily available yet.

Definition at line 90 of file RE_TimerQuery.h.

void RE_GPUTimer::init ( RE_Render * r )

inline

Initialize the queries (queries cannot be created if a query is running)

Definition at line 58 of file RE_TimerQuery.h.

bool RE_GPUTimer::isResultAvailable ( RE_Render * r )

inline

Returns true if the query result is available from the GL server.

void RE_GPUTimer::reset ( void )

inline

Reset the queries without deleting them.
