Abstract:
We present a novel algorithm for accurate, high quality
point rendering, which is based on the formulation of
splatting using homogeneous coordinates. In contrast to
previous methods, this leads to perspective correct splat
shapes, avoiding artifacts such as holes caused by the
affine approximation of the perspective projection. Further,
our algorithm implements the EWA resampling filter,
hence providing high image quality with anisotropic
texture filtering. We also present an extension of our rendering
primitive that facilitates the display of sharp edges
and corners. Finally, we describe an efficient implementation
of the entire point rendering pipeline using vertex
and fragment programs of current GPUs.
