I have improved the performance of:
www.polyarc.us/packer.js
for "on-the-fly" poly encoding.
Convergence is expedited in some cases with multiple pivots (one above
the line / one below the line) per recursion cycle. Point reduction
accompanies the construction of the dreadful zoom string. Pixel
coordinates rather than Lat/Lon coordinates are used to reduce bias.
Fixed point comparisons rather than floating point comparisons are
used to boost speed as well as accuracy. Ties are resolved
deterministically. The results are consistent in either direction.
For static polys, try:
www.polyarc.us/pack/static
For dynamic polys, try:
www.polyarc.us/pack/dynamic
An alert will appear following the encoding. In addition to loading
speed, panning speed & zooming speed are worth consideration.
