Dome was an experimental 3D game. It used QuickDraw 3D for a graphics engine.
The camera was selectable as the active dome (it hovered behind the line of fire and rose higher if terrain got in the way) or an aerial view. (There was also support for a roving truck, though the physics of the truck were very rough.)
Most of the quality settings were adjustable, and the frame rate for the picture shown was acceptable even on the lowest-end Power Macintosh made: the 60 MHz Power Mac 6100 with the unaccelerated 32-bit AV card.

Power Macintosh (60 MHz and up), System 7.5.3, QuickDraw 3D.
