by the way, the formal term for displaying only visible polygons is occlusion culling, which might be helpful in finding relevant articles. also, a method you could use is pre-determining what polygons are visible from certain sectors in a map and storing that in along with the map data, rather than trying to calculate it in real time. that wouldn't be much help for dynamic terrain, though...

edit: this is probably just going to be me ranting, and not be of any actual use, but i had an idea while walking home just now that would be perfect for a 'closed rooms and corridors' shooter like doom. instead of storing the map data in a giant 3d grid, it could be stored in sectors, each sector with its own map of polygons that are to be drawn while the player is within it. por ejemplo:
if you had a 2d map for a raycaster, instead of using the conventional method, it could be broken up into sectors, like so:


and then each sector would be stored separately and consist of all the blocks that are potentially visible from within its X,Y region of the total map. here are sectors 1-3:
   

as you can see, some sectors can be a lot larger than others. however, it would be easy to minimise such areas when designing the maps by making sectors room-sized, and things like that. additionally, all the white space would make compression pretty easy =)

I really want demo

you'd have to have some way of dynamically updating all the separate sectors, that contain a certain block, so not realistically, no. like i said:

Wow... That's a lot of posts !
Thanks for the support

This looks awesome Chockosta! how big will be maps? Glad you're still working on this.

The total map is 100*100*40 (400,000 cubes !)
I display a chunk of 24*24*24 around the player. (with scrolling)

[nice ideas]

Your idea seems nice, but I think it's more adapted to a raycasting 3D engine... Because with nCraft, the sectors could get way too big.
Moreover, DJ is right, it would be hard to update sectors.

I have to get CX support, and then, I will put a download. (Even if it would be pretty useless without the possibility to add/remove blocks)


Oh, and sorry for using servimg, I should find another image hosting website.

.

still I like the generator

You should probably ask your question in the C or Ndless section later too if you don't get any reply here, since more people who can help might see it in an help section.
