I've just created my first Processing sketch using OpenGL and, while I've been delighted by how easily I can create an applet, I'm disappointed that my applet won't load without a scary security warning message.

On the Mac I see:
This applet was signed by "sun microsystems, inc," but Java cannot verify the authenticity of the signature's certificate. Do you trust this certificate?

Java can't verify the authenticity of a certificate from Sun? If I were a naive user and I got this message coming to a website, I'd be very wary about clicking the "Trust" button.

Is this problem specific to some security configuration on my Mac, or is this an inherent consequence of using OpenGL in an applet?

I did not originally code my sketch using OpenGL. I first built a 3D animation using a P3D view, but the applet was eating up 50% of my CPU cycles. I recoded using GL display lists and the CPU usage is down to 3%.

Can I avoid using OpenGL/JOGL by doing something with Processing 3D that will be equivalent to display lists?

Thanks for helping orient me to the Processing Way(tm.)
