Member Function Documentation

GLF_API void GlfGLQueryObject::Begin ( GLenum  target)

Begin query for the given target target has to be one of GL_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED_CONSERVATIVE, GL_PRIMITIVES_GENERATED GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN GL_TIME_ELAPSED, GL_TIMESTAMP

GLF_API void GlfGLQueryObject::BeginPrimitivesGenerated ( )

equivalent to Begin(GL_PRIMITIVES_GENERATED). The number of primitives sent to the rasterizer by the scoped drawing command will be returned.

GLF_API void GlfGLQueryObject::BeginSamplesPassed ( )

equivalent to Begin(GL_SAMPLES_PASSED). The number of samples that pass the depth test for all drawing commands within the scope of the query will be returned.

GLF_API void GlfGLQueryObject::BeginTimeElapsed ( )

equivalent to Begin(GL_TIME_ELAPSED). The time that it takes for the GPU to execute all of the scoped commands will be returned in nanoseconds.

GLF_API void GlfGLQueryObject::End ( )

End query.

GLF_API int64_t GlfGLQueryObject::GetResult ( )

Return the query result (synchronous) stalls CPU until the result becomes available.

GLF_API int64_t GlfGLQueryObject::GetResultNoWait ( )

Return the query result (asynchronous) returns 0 if the result hasn't been available.
