Settings

This branch gives options to set the openGL properties.

Enable Transparency Specify whether to enable transparency. This is also controlled by the system variable @OGLT.
  • Enable
  • Disable

Note:Transparency is disabled for OpenGL version lower than 2.1.

Enable Anti-aliasing Specify whether to enable anti-aliasing. Hint message will show below when an option is selected.This is also controlled by the system variable @OGLFA.
  • No anti-aliasing
  • Multi-samples anti-aliasing
This gives the best quality of anti-aliasing, but the speed will be relevantly slower.
  • Fast approximate anti-aliasing
This gives faster speed than multi-samples anti-aliasing but the quality may not be as good.

Note:Anti-aliasing may not work for all openGL versions lower than 2.1.0 (including 2.1.0).

Enable Anti-aliasing for Export/Print Specify whether to enable anti-aliasing when exporting or printing graphs.This is also controlled by the system variable @OGLFAE.

The options are the same with the Enable Anti-aliasing drop-down list.

Enable Display List Specify whether to use the display list. This is also controlled by the system variable @OGLDL.

This is only useful when openGL version is higher than Intel 3.3. This shall be used if enabling transparency make the plot disappear.

Note:@OGLDL=0 means disable display list and @OGLDL=1 means enable.
