Ethernet passive optical network (EPON) is one of the potential solutions for the next generation access technology. Its economical equipment and maintenance costs are particularly attractive to telecommunication service providers. The EPON has a tree topology and the upstream bandwidth from optical network terminals to the optical line terminal is shared.(More)
We propose a method for three-dimensional surface details mapping and rendering based on conventional relief texture mapping. The depth extrema of intersection points within a viewing cone are computed and stored in a minmax texture in the preprocessing time. This texture is then used to narrow down the search space of ray-height-field intersection during(More)
