Use OpenGL or ActiveX to make 3d polar plot??

[rmoscoso]

Using LabWindows/CVI 8.1 and want to know if one is better.  Any problems that may be encountered??

Basically plotting the output of LEDs in 3D (output usually cone-shaped with dome at end).

Thanks-

Hi Rmoscoso,

In general, either the 3D ActiveX graph or the built in OpenGL methods within CVI should allow you to accomplish what you want to do.  The 3D ActiveX graph uses OpenGL underneath the hood so the performance between the two should be comparable.  You might have a little more control with the CVI OpenGL methods, but if you are plotting something fairly simple, it shouldn't really make too big of a difference.  Hope this helps!

Besides OpenGL.org, is there any reading/resource you would recommend??  Not experienced with OpenGL.

Thanks-

Hi Rmoscoso,

OpenGL.org is a really good reference.  This site is also pretty good.  They have links to several tutorials.
