Version 3.0 (beta) Search for an algorithm that allows a changing 2.5D surface to be rendered in real time in most fastest way, with polygon count reduction only. To archive this, the input data is bidimensional matrix with height values and no additional data.

2.1. First release results

Reduction is effective, we go from 2048 polygons to +/- 700 in a first iteration (65% reduction). But It's too slow, because a single point modification implies the recalculation of the full heightfield. The time to make a reduction of a 32x32 grid is 3 secs (due multipass). This idea has been rejected by now.
