I made this a few years ago. Inspired by Morgan, this is a more modern version (somwere from 1960s I suspect :wink
. Alhough the Harley engine is from late 1990s.
It's not just based on my imagination, I loosely calculated the shape, weight distributions, etc. The thing has a triangulated spaceframe (I even borrowed some books from the library on racing car frames for that project). However the thing is far from being perfect, I know.
Most of the modeling was done Rhino, though a lot of this was coded directly in POV-Ray (frame, suspension, wheels, steering column, windshields, lamps, etc.) As you might have expected, POV-Ray was used for rendering.
