Screen Refresh: Controlling Graphics Window Redraws

Screen Refresh: Controlling graphics window redraws

Normally graphics images in D3PLOT redraw at an acceptable speed, and the delay when refreshing "holes" left by menus popped up in front of the graphics window are not objectionable.

However if you are running a large model on a slow machine this may become a problem, and it is possible to turn off screen refreshes using Options > Screen Refresh . This will leave black holes when menu panels are unmapped, and you will have to issue an explicit redraw command to get rid of these. You can turn the refresh switch on again at any time.

You can save the graphics refresh status in the "oa_pref" file with the line: d3plot*graphics_refresh: off | on The default is "On".

Note : Unlike PRIMER no "backing store" drawing is used in D3PLOT, so issues such as Bitmaps, Pixmaps and PBuffers do not arise.
