this will draw a 3d line from point a to point b in 3d space ..

it will be 1 pixel wide over the whole lenght

to color it you may have to texture the object

each line requires one tri and that you have upgraded to U58(final pref) ( sounds like a sub designation ) ;D

don't know if anyone else finds this usefull .. but i need it for displaying waypoints and movements for my 3d space thing (nice name eh!) 8)
many uses abound.. and when textured and no wire frame good beam weapons can be made . "real" looking lazers LOL

you can do this with out U58 ..but you have to use mesh / memblock commands or DKshop.dll or .. yuck .. deleting the tri every call for dbc users.

I read this post only now but it's interesting.
I've got db pro ver 5.2 and it will not run so is it possible to
make a 3d line without memblock ? thanks.

Darkbasic is great !

yah if you use DKshop.dll .. it will give you acces to low level poly data.

the original version of my 3d line was built that way.

and the earlier version slow but worked was to delete and recreat a tri every call to same line, when you want to move it ..

just set the last two point of the tri to the same place and it becomes a line

it should be

should it not? vertex index starts at 0, not 1, so you moved a non existant vertex and didn't move vertex 0

Why not just delete the object?
