all-polygons clj/s

(all-polygons {:keys [front back] :as node})

Returns vector of all polygons of the given CSG node and its children.

clip clj/s

(clip {:keys [front back] :as a} b)

Clips the polygons of the first node with the ones from the second. Returns the updated node.

clip-polygons clj/s

(clip-polygons {:keys [plane front back] :as node} ps)

Uses a CSG node's plane to recursively clip the given seq of polygons. Returns a flat seq of polygons classified as in-front of the plane or the original seq if no clipping plane is available.

csg->mesh clj/s

(csg->mesh node)

(csg->mesh mesh node)

csg-cone clj/s

(csg-cone s e r-south r-north res)

csg-node clj/s

(csg-node polygons)

(csg-node {:keys [polygons plane front back] :as node} ps)

Creates a new or refines a CSG tree node and recursively adds the given polygons to it.

csg-polygon clj/s

(csg-polygon vertices)

(csg-polygon vertices shared)

Creates a CSG polygon map from the given vertices and computes a plane definition using the first 3 vertices.

split-poly clj/s

(split-poly {:keys [n w]} poly state)

Takes a plane and splits the given polygon with it. Returns a 4-element vector of classified sub-shapes: [coplanar-front coplanar-back front back].
