Hybrid point and line segment models rendered
by our method.
Bridging the modelling and
rendering gap between the existing triangle and point primitives,
we explore the use of line segments as a new primitive to
represent and render 3D models. Our main contribution extends
the anti-aliasing theory in texture mapping to anti-aliased
line segment rendering, and presents an approximation algorithm
to render high quality anti-aliased opaque and transparent
line segments in 3D models. This anti-aliasing technique is
empirically validated by building a software pipeline to render
models of any combination of the three types of surface primitives:
triangles, line segments and points. Experiments show that
models comprising line segments are potentially efficient
and effective for high quality rendering as compared to their
corresponding pure point models.
