Huge F1-ATPase surface (~800,000 triangles) colored by semi-transparent electrostatic potentials. Two copies are shown, the right one being rotated by 90 degrees along the x-axis.

After a quick rendering test, the final command-line is:

<command> +i <file> +w1000 +h500 -f +a0.2 +am2 +r2
The -f option prevents writing files which often slows down calculation, especially across network. For the same reason, display is not used.
