apply-voxels clj/s

(apply-voxels f tree coll)

as-array clj

(as-array tree min-depth)

bit-vals clj/s

cell-index clj/s

(cell-index stride stride-z x y z)

Returns the index for the cell at xyz with stride and stride-z.

delete-at clj/s

(delete-at tree v)

(delete-at tree offset dim idx depth max-depth branches v)

depth-at clj/s

(depth-at tree v)

(depth-at tree max-depth v)

(depth-at tree offset dim idx depth max-depth branches v)

Returns max defined tree depth at given position.

depth-index clj/s

depth-size clj/s

max-depth clj/s

(max-depth dim prec)

Returns max tree depth for the given size and min requested precision (voxel size).

node-bitmask clj/s

(node-bitmask o dim p)

node-id clj/s

(node-id [ox oy oz] dim [px py pz])

node-index clj/s

(node-index idx id d sizes)

select clj/s

(select tree min-depth)

(select data offset dim idx depth min-depth branches acc)

select-cells clj/s

(select-cells tree min-depth)

(select-cells data offset dim idx depth config branches acc)

set-at clj/s

(set-at tree v)

(set-at tree offset dim idx depth max-depth branches v)

Marks voxel at given position as set. Updates tree at all levels.

size-at-depth clj/s

(size-at-depth dim depth)

Returns node size at depth for given tree bounds.

used-bits clj/s

Returns a lazy-seq of bit ids used in x. Only checks 8bit range (0 - 255).

voxel-cell clj/s

(voxel-cell {:keys [size stride stride-z]} idx)

Returns the cell coordinate for the given index and tree configuration as vec3 (the latter obtained via voxel-config-at-depth).

voxel-config-at-depth clj/s

(voxel-config-at-depth {:keys [dim max-depth] :as tree} min-depth)

Returns a map of configuration settings for the given tree and depth. Depth will be clamped at tree's max-depth.

voxel-coord clj/s

(voxel-coord config idx)

Returns the actual world space coordinate for the given index and tree configuration (the latter obtained via voxel-config-at-depth).

voxeltree clj/s

(voxeltree dim prec)

Creates a new voxel tree structure with the given root node dimension and min precision.
