Parameters - Perform Page

Active active - Turns logging on/off. The DAT will continuously log while Active is On. Use resetpulse button to the right to grab a single frame snapshot.  

Active Pulse activepulse -  

Trigger Mode triggermode - - Offers two options for when to trigger a refresh of the logs.

  • When Frame Length Exceeds Threshold threshold - Use the Trigger Threshold parameter below to set a maximum frame time to wait before refreshing the log.
  • When a Frame is Dropped droppedframe - Refresh the log as soon as a frame is dropped.

Trigger Threshold triggerthreshold - This is the amount of time, in milliseconds, that a frame must exceed to cause the DAT to log and output the frame's timing. For example to see what happens when a frame takes more that 33 ms to cook, put this parameter to 33.  

Cook Time logcook - Logs the cook time of operators.  

Export Time logexport - Logs time spent exporting CHOP channels.  

Viewport Draw Time logviewport - Logs time to draw 3D geometry and SOP viewers.  

Movie Time logmovie - Logs time taken to read video and audio from movie files.  

Draw Channels Time logdrawchannels - Logs time to draw channels in CHOP viewers.  

Object View Time logobjectview -  

Custom Panel Time logcustompanel - Logs time taken by custom panels build with Panel Components.  

MIDI Time logmidi - Logs time spent on MIDI.  

Graphics Time loggraphics - Logs various graphics system calls, such as time spent waiting for the graphics card, calls to the graphic driver, converting TOP data to CHOPs, etc.  

Frame Length logframelength - Logs total frame time in milliseconds (ms).  

Misc logmisc - Logs miscellaneous times that do not fit into other categories.  

Script logscript - Logs time spent running scripts.  

Render logrender - Logs time spend by Render or Renderpass TOPs.  


Parameters - Common Page

Language language - - Select how the DAT decides which script language to operate on.

  • Input input - The DAT uses the inputs script language.
  • Node node - The DAT uses it's own script language.

Edit/View Extension extension - - Select the file extension this DAT should expose to external editors.

  • dat dat - various common file extensions.
  • From Language language - pick extension from DATs script language.
  • Custom Extension custom - Specify a custom extension.

Custom Extension customext - Specifiy the custom extension.
