Abstract
Bézier surfaces have been widely employed in the designing of complex scenes with high-quality results. Nevertheless,
parametric surfaces cannot be directly rendered in the current GPUs of modern handheld devices. This
work proposes a non-adaptive method for tessellating Bézier surfaces on a GPU without primitive generator, such
as the GPUs implemented in handled devices. Our technique is based on the utilization of a parametric map of
virtual vertices, and its operation can be adapted to the hardware resources available in the GPU by tuning a series
of parameters. Additionally, an analysis of the most relevant hardware constraints in the graphics hardware of the
current handheld devices has been carried out. As those constraints prevent interactive high-quality results from
being achieved, even with our proposal, we present an algorithmic approach focused on the real-time rendering on
future handheld devices.
