A single test is composed of a series of individual latency measurements -// which are used to derive min, max, and an average latency value. -// -// Developers are required to call the following methods: -// SetDevice - Sets the LatencyTestDevice to be used for the tests. -// ProcessInputs - This should be called at the same place in the code where the game engine -// reads the headset orientation from LibOVR (typically done by calling -// 'GetOrientation' on the SensorFusion object). Calling this at the right time -// enables us to measure the same latency that occurs for headset orientation -// changes. -// DisplayScreenColor - The latency tester works by sensing the color of the pixels directly -// beneath it. The color of these pixels can be set by drawing a small -// quad at the end of the rendering stage. The quad should be small -// such that it doesn't significantly impact the rendering of the scene, -// but large enough to be 'seen' by the sensor. See the SDK -// documentation for more information. -// GetResultsString - Call this to get a string containing the most recent results. -// If the string has already been gotten then NULL will be returned. -// The string pointer will remain valid until the next time this -// method is called. -// - -class LatencyTest : public NewOverrideBase -{ -public: - LatencyTest(LatencyTestDevice* device = NULL); - ~LatencyTest(); - - // Set the Latency Tester device that we'll use to send commands to and receive - // notification messages from. - bool SetDevice(LatencyTestDevice* device); - - // Returns true if this LatencyTestUtil has a Latency Tester device. - bool HasDevice() const - { return Handler.IsHandlerInstalled(); } - - void ProcessInputs(); - bool DisplayScreenColor(Color& colorToDisplay); - const char* GetResultsString(); - - bool IsMeasuringNow() const { return (State != State_WaitingForButton); } - - // Begin test.
