Put a cube by [Primitive] command, and set 89 or 91 degrees to the smooth angle.
You can find the difference.

Thanks for your reply, I can understand 'smooth shading' option is like enable the glShadeModel(GL_SMOOTH).I just want to know how the smooth angle works in the shading, is it work in normal calculation or something else?

Smooth angle affects the normal calculation.
Plug-in SDK contains a source code for the normal calculation. Please refer MQ3DLib.cpp if you understand C++ program.

Thanks, that really helps a lot. But do you have MQ3DLib.cpp with english annotation?

We will release a new sdk for the next update; Ver4.3.
And it will contain English annotation for the normal calculation.
Please wait a moment.
