Is there an octree package for Common Lisp? I.e. something that would allow setting voxel on/off and then do A-star on resulting big cubes.

And they use OOP. Ever tried to merge code from two independent OOP projects, each using it's own hierarchy of classes?

So study the design and adapt it for your own purpose. The freedom to tinker is the reason why the free software movement exists.

So basically I need following, but optimized:
octree D = H:log 2 D | int = T:0 = p2i:<[X Y Z] = Z*4+Y*2+X> = o get:<P = with D P T <:descend L P T = !L%2 = T,<S:int?=S; T = I: p2i P%L = P: mod P L = descend L P T,I> >> set:<P V = !T: with D P T <:descend L P T = !L%2 = T,<S:int? = {ptrEq L 0 |v ptrEq V S = V; vec 8 I:S | r} ;T = I: p2i P%L = P: mod P L = R: descend L P T,I = R,<[X:int?@(?|all:Y ptrEq X Y)]=!R:X> = aset I R T = T> >>

I cant believe there is no octree implementation. It isn't much longer than a factorial.

There is relativele clean Scheme version, but it is for colors:

Boris (Baruch) Pasternak is Jewish, and so is his character Zhivago.

http://en.wikipedia.org/wiki/Boris_Pasternak
Pasternak was born into a wealthy assimilated Russian Jewish family.

I believe mentioning that his family was "wealthy" is redundant, because all Jews are fucking wealthy compared to goyim.

Here is my nearest-neighbour discovery algorithm:
1. push random sub-quad inside this quad onto processing stack
2. pop top quad and for each it's edge's segment push quad, containing this segment, onto processing stack
3. if stack isnt empty, goto 2.

Note: hash poped quads by their XYZ

it should be faster than just poping every voxel.
