jashkenas / perspective.rb
Created May 12, 2009 23:55
# Move the mouse left and right to change the field of view (fov).
# Click to modify the aspect ratio. The perspective method
# sets a perspective projection applying foreshortening, making
# distant objects appear smaller than closer ones. The parameters
# define a viewing volume with the shape of truncated pyramid.
# Objects near to the front of the volume appear their actual size,
# while farther objects appear smaller. This projection simulates
# the perspective of the world more accurately than orthographic projection.
# The version of perspective without parameters sets the default
# perspective and the version with four parameters allows the programmer
