Begins a capture interval that will end with EndCapture.
Syntax
void BeginCapture();
Remarks
A capture interval typically spans a subset of one frame, such as when you want to capture graphics information only about a certain kind of draw call. If the capture interval spans a call to present, then two frames of graphics information are captured. The first frame spans the interval between the call to BeginCapture and the call to present; the second frame spans the interval between the first Direct3D event after the call to present and the call to EndCapture.
To capture an interval, you must prepare your app to capture and record graphics information—that is, you must have called Init through an instance of the VsgDbg class before you call BeginCapture or EndCapture.
