how many dots a model have to have?
e.g. if you render a tree from distance its about 500 dots (rendered pixles) but if you zoom to a leaf fullscreen (1600x1400) only this leaf must have ~2.2Mpix!
(and then zoom to more detail laugh )

The challenge of dot-cloud-models is not the select the visible dots but to handle the dots in memory ("unlimited amount of data..." [vpos 7:02])

(for me it's nonsens [the way it is showed])

ps: cool mozart music! wink
pps: nothing is impossible - so let's stay tuned
