[OpendTect_Users] need help

[Yuancheng Liu]

Hello, Nayyer,

I am glad the trick works for you.

To answer your question, OpenGL shading is a programming technique used 
in OpenGL which gives some specific affects in display.  We use shading 
in OpendTect to make better, crispier display if the users' graphics 
cards support it. You can see a big difference when display objects in 
the scene if you turn on and off the shading.

Unfortunately, not all graphic cards support shading, especially those 
old ones. Also, different brands may support differently. Based on what 
I know, Nvidia cards may behave better than ATI cards in OpendTect.

Best regards,

Yuancheng Liu
