class BatchDropCutter : public ocl::Operation

BatchDropCutter takes a MillingCutter, an STLSurf, and a list of CLPoint’s and calls MillingCutter::dropCutter() for each CLPoint. To find triangles overlapping the cutter a kd-tree data structure is used. The list of CLPoint’s will be updated with the correct z-height as well as corresponding CCPoint’s Some versions of this algorithm use OpenMP for multi-threading.

class MillingCutter

MillingCutter is a base-class for all milling cutters.

Subclassed by ocl::BallCutter, ocl::BullCutter, ocl::CompositeCutter, ocl::ConeCutter, ocl::CylCutter

Public Functions

bool overlaps(Point &cl, const Triangle &t) const

Test if the cutter bounding-box, positioned at cl, overlaps with the bounding-box of Triangle t. works in the xy-plane

bool vertexDrop(CLPoint &cl, const Triangle &t) const

drop cutter at (cl.x, cl.y) against the three vertices of Triangle t. calls this->height(r) on the subclass of MillingCutter we are using. if cl.z is too low, updates cl.z so that cutter does not cut any vertex.

virtual bool facetDrop(CLPoint &cl, const Triangle &t) const

drop cutter at (cl.x, cl.y) against facet of Triangle t calls xy_normal_length(), normal_length(), and center_height() on the subclass. if cl.z is too low, updates cl.z so that cutter does not cut the facet. CompositeCutter may be the only sub-class that needs to reimplement this function.

virtual bool edgeDrop(CLPoint &cl, const Triangle &t) const

drop cutter at (cl.x, cl.y) against the three edges of input Triangle t. calls the sub-class MillingCutter::singleEdgeDrop on each edge if cl.z is too low, updates cl.z so that cutter does not cut any edge.

bool dropCutter(CLPoint &cl, const Triangle &t) const

drop the MillingCutter at Point cl down along the z-axis until it makes contact with Triangle t. This function calls vertexDrop, facetDrop, and edgeDrop to do its job. Follows the template-method, or “self-delegation” design pattern. if cl.z is too low, updates cl.z so that the cutter does not cut Triangle t.

bool dropCutterSTL(CLPoint &cl, const STLSurf &s) const

call dropCutter on all Triangles in an STLSurf drops the MillingCutter at Point cl down along the z-axis until it makes contact with a triangle in the STLSurf s NOTE: no kd-tree optimization, this function will make dropCutter() calls for each and every Triangle in s.
