Displays profile results of rendering using the GD library with the nngx
API.
None.
None.
This uses the GD library to implement DrawPrimitive
, which is a sample demo for the GR library.
The following macros are defined in the source code. By specifying these for PACKET_RECORDING_MODE
, you can switch to an implementation that uses the gd::System::StartRecordingPackets
function.
USE_PACKET_RECORDING_NONE |
Do not use the StartRecordingPackets function. |
---|---|
USE_PACKET_RECORDING_COPY |
Use the StartRecordingPackets function (specify RECORD_COMMAND_LIST_COPY to the usage parameter). |
USE_PACKET_RECORDING_NOCPY |
Use the StartRecordingPackets function (specify RECORD_COMMAND_LIST_NO_COPY to the usage parameter). |
The demo displays the following screens when run. Adjust the stereoscopic image with the 3D depth slider.
The following type of profile results are periodically output to the debugger.
