BUGLE-TRACE(7)		       Bugle user manual		BUGLE-TRACE(7)

NAME
       bugle-trace - record a log of OpenGL calls made

SYNOPSIS
       filterset trace
       filterset log
       {
	   filename "trace.txt"
       }

DESCRIPTION
       This filter-set provides a log of the OpenGL calls made. For each call,
       the function name, the parameters and the return value (if any) are
       recorded. Where appropriate, symbolic names are shown for GLenum
       parameters, and pointers are followed to show the correct number of
       elements.

OPTIONS
       There are no options to control this filter-set. All logging is done
       through bugleĀ“s logging system (see bugle-log(7)), and options such as
       filename and log format can be modified there.

OUTPUT
       Here is a sample log output

	   [INFO] trace.call: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
	   [INFO] trace.call: glLoadMatrixd(0xbfffe610 -> { { 0, -0.29661, 1.22295, 0 }, { 1.22295, 0, 0, 0 }, { 0, 1.18644, 0.305739, 0 }, { 0.037888, 1.61781, -1.52576, 1 } })
	   [INFO] trace.call: glActiveTextureARB(GL_TEXTURE0)
	   [INFO] trace.call: glTexEnvfv(GL_TEXTURE_ENV, GL_TEXTURE_ENV_COLOR, 0xbfffe5d0 -> { 0.778524, 0.778524, 0.569631, 0 })

BUGS
       Some enumerants share values, so you may see a different symbolic name
       in the log than in your source code. It is believed that this should be
       limited to cases where extensions share a value for semanticly
       equivalent symbols; if you find a case where this is not true, please
       inform the author.

       Because the filter-set examines arguments and follows pointers, it is
       possible to crash it by passing invalid values, particularly invalid
       pointers.

BACKWARDS COMPATIBILITY
       In previous versions, the trace filter-set also reported OpenGL errors
       to the log. This is now handled by the showerror filter-set (see bugle-
       showerror(7)).
