How do you handle cases with multiple coplanar polygons? -- Merge polygons, which are at the same cell. - -3. Can we avoid kinetic completely? -- Probably yes, but there is a problem of how to find the correct criteria that guarantees the volume convexity.

Is this number optimal for each k? -- No, it is super difficult. - -5. When two polygons intersect at the very beginning, does it count as an intersection?

Better future directions, compute them exactly and identify if the lines are parallel using the segment coordinates, unify them for all types of events, the function should take two points with the directions and two fixed points and return the future point and the future direction along the edge, one direction must be the limit direction and one direction must be the cropped direction. -2.

Fix initialization using the same trick I use for adding missing faces. -7. Put adding missing faces and remove faces in two separate files, they can be reused when working on the subdivision. -8. Add the finalizer class. -9. Make the initializer work with the inexact kernel. -10. Better polygon regularizer using the global approach. -11. Graph cut using normals and graphcut using the LOD. -12. Add timing tests, better tests, accelerate the code as much as possible. -13.

+ +\mainpage User Manual +\anchor Chapter_Kinetic_Shape_Partition +\cgalAutoToc + +\authors Simon Giraudot, Dmitry Anisimov and Sven Oesau + +\section Ksp_introduction Introduction + +This \cgal component implements the kinetic shape partition proposed by Bauchet et. al \cgalCite{bauchet2020kinetic}. It takes as input a set of planar shapes, e.g. polygons, and partitions the bounding box of the input into polyhedra, whereas each polyhedron and its facets are convex. Each facet of the partition is part of the 2D convex hull of an input polygon or an extension of it. + +The kinetic partition homogeneously expands the convex hull of each input polygon until collisions occur between them. At each collision, their expansion may stop, they may restrict the propagation along an intersection line or they may continue beyond the intersection line. The polygons are split at the start of the partition and at each collision along the intersection line to be intersection-free. + +Whether a polygon is expanded beyond an intersection with another polygon, depends on the user specified `k` parameter. Choosing `k = 1` will cause the expansion of polygons to locally stop at the first intersection with another polygon and choosing `k` equal to the number of input planes will lead to a full expansion of each polygon to the bounding box. + +\section Ksp_algorithm Algorithm +The first step of the method creates an intersection graph of the planes of the input polygons. Input polygons that are coplanar are merged into their convex hull. +The intersection graph contains all points and lines of the intersections between the planes and the bounding box. For each support plane, i.e., the plane of an input polygon, all intersections with the bounding box and other support planes are given by lines edges and vertices of the graph. The kinetic partition created in the second step is a subset of faces of the intersection graph depending on the `k` parameter. + +\cgalFigureBegin{Ksp_introductionfig,intersection_graph.png} +Intersection graph.\n +Left: 4 polygons as input. Right: intersection graph of polygons and bounding box together with input. +\cgalFigureEnd + +The kinetic partition for a chosen `k` is obtained by propagating each polygon within its support plane. As intersections with other polygons can only occur at the known edges in the intersection graph, the 3D collision problem can be solved as separate 2D polygon edge collisions. + +\cgalFigureBegin{Ksp_algorithmfig,k_variation.png} +Impact of `k` parameter on partition.\n +Left: Intersection graph with 4 input polygons. Right: three columns with propagated polygons on top and volumes of kinetic partition on bottom for `k` = 1, `k` = 2 and `k` = 3 from left to right with 5, 8 and 12 created volumes respectively. +\cgalFigureEnd + +\subsection Ksp_parameters Parameters + +The algorithm has five parameters: + +- `k`: +The main parameter of this method is `k`, the maximum number of intersections that can occur for a polygon before its expansion stops. The initial intersections of the original input polygons are not considered. Thus increasing the `k` leads to a higher complexity of the partitioning, i.e., a higher number of facets and a higher number of volumes. For a certain `k` the partition can be considered to be complete and an increase in `k` will not further increase the complexity of the partition. + +- `reorient_bbox`: +The default bounding box of the partition is axis-aligned. Setting `reorient_bbox` to true aligns the x-axis of the bounding box with the direction of the largest variation in horizontal direction of the input data. + +- `bbox_dilation_ratio`: +By default the size bounding box of the input data is increased by 10% to avoid that input polygons are coplanar with the sides of the bounding box. + +- `angle_tolerance` and `distance_tolerance`: +The input polygons can be clustered to reduce the number of very thin and very small cells. Two polygons are clustered into one if the deviation between their plane normals is below `angle_tolerance` and the maximum distance of one polygons centroid to the others plane is less than `distance_tolerance`.

It takes as input a set of planar shapes, e.g. polygons, and partitions the bounding box of the input into polyhedra, where each polyhedron and its facets are convex. Each facet of the partition is part of the 2D convex hull of an input polygon or an extension of it. The kinetic partition homogeneously expands the convex hull of each input polygon until collisions occur between them.

Seems difficult, because the vertex can be part of plenty new edges. - // Can it? The overlay is a fusion of 2 cdts, so if there are more than two edges intersecting in a vertex, there were already two edges intersecting in one of the cdts - // So no, each new vertex can only be part of 2 edges - - // Adjusting edges part of faces that are not part of the splitting plane is basically a function of split_edge(Index_head, Index_tail, new_mid_vertex) - // Identifying the faces based on the vertices seems costly. PEdge to PFaces exists, check for PFace to volume - // // -> does not work for newly inserted edges! Newly inserted edges do not have PEdge! - // Otherwise it is possible to find adjacent volumes based on the participating faces. However, an edge on the boundary can be part of many faces/volumes - - // Approach: - // Loop over finite faces of fusioned cdt - // check if face was already handled (-> reuse field in face info?) - // check if face is on border to face of another index pair - // start face extraction - // follow border and build up polygon vector - // check if there is a vertex index in the vertex info, if not insert vertex into partition.data_structure and update - // create map for boundary vertices correspondences - // check if replace face in data structure or create new one (set which contains replaced ones?) } void make_conformal(Octree_node node) { @@ -3357,21 +3110,6 @@ class Kinetic_shape_partition_3 { make_conformal(lower, upper, plane); -/* - lower.clear(); - upper.clear(); - // Todo: remove check - collect_opposing_faces(node, dim, lower, upper, plane); - - for (std::size_t i = 0; i < lower.size(); i++) { - auto n = neighbors(lower[i]); - assert(n.first >= 0 && n.second >= 0); - } - - for (std::size_t i = 0; i < upper.size(); i++) { - auto n = neighbors(upper[i]); - assert(n.first >= 0 && n.second >= 0); - }*/ } } From 465d5084a04f270f2b9546c8887868635a6eaaeb Mon Sep 17 00:00:00 2001 From: Sven Oesau Date: Tue, 14 Nov 2023 15:35:02 +0100 Subject: [PATCH 440/512] removed tabs fixed doc links --- .../Concepts/KineticLCCFaceAttribute.h | 2 +- .../Concepts/KineticLCCVolumeAttribute.h | 2 +- .../include/CGAL/Kinetic_shape_partition_3.h | 10 +++++----- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCFaceAttribute.h b/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCFaceAttribute.h index c3685118d455..6fbb45c45a35 100644 --- a/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCFaceAttribute.h +++ b/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCFaceAttribute.h @@ -17,7 +17,7 @@ The concept `KineticLCCFaceAttribute` refines `CellAttribute` to store additional information for each face related to its associated input polygon. \cgalHasModelsBegin -\cgalHasModelsBare{\link Cell_attribute `Cell_attribute`\endlink} +\cgalHasModelsBare{\link CGAL::Cell_attribute `Cell_attribute`\endlink} \cgalHasModelsEnd \sa `CGAL::Kinetic_shape_partition_3` diff --git a/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCVolumeAttribute.h b/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCVolumeAttribute.h index b3a9df95f4e9..dda93a14b6bd 100644 --- a/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCVolumeAttribute.h +++ b/Kinetic_shape_reconstruction/doc/Kinetic_shape_reconstruction/Concepts/KineticLCCVolumeAttribute.h @@ -17,7 +17,7 @@ The concept `KineticLCCVolumeAttribute` refines `CellAttribute` to store the barycenter and an id. \cgalHasModelsBegin -\cgalHasModelsBare{`Cell_attribute`} +\cgalHasModelsBare{\link CGAL::Cell_attribute `Cell_attribute`\endlink} \cgalHasModelsEnd \sa `CGAL::Kinetic_shape_partition_3` diff --git a/Kinetic_shape_reconstruction/include/CGAL/Kinetic_shape_partition_3.h b/Kinetic_shape_reconstruction/include/CGAL/Kinetic_shape_partition_3.h index e8c73ba35680..621d51d6e9af 100644 --- a/Kinetic_shape_reconstruction/include/CGAL/Kinetic_shape_partition_3.h +++ b/Kinetic_shape_reconstruction/include/CGAL/Kinetic_shape_partition_3.h @@ -58,8 +58,8 @@ namespace CGAL { /*! * \ingroup PkgKineticShapePartitionRef \brief creates the kinetic partition of the bounding box of the polygons given as input data.

Input polygons that are coplanar are merged into their convex hull. -The intersection graph contains all points and lines of the intersections between the planes and the bounding box. For each support plane, i.e., the plane of an input polygon, all intersections with the bounding box and other support planes are given by lines edges and vertices of the graph. The kinetic partition created in the second step is a subset of faces of the intersection graph depending on the `k` parameter. +The first step of the method creates a plane arrangement between the support planes of the input polygons. The computation of a plane arrangement has O(\f$n^3\f$). To speed up the computation the input data can be decomposed into separate kinetic partitions using an octree. The decomposition limits the expansion of an input polygon to octree nodes it initially intersects. The usage of an octree significantly speeds up the creation of the kinetic partition. However, it adds facets to the partition which originate from the octree and do not belong to an input polygon. +The plane arrangement contains all points and lines of the intersections between the support planes and the bounding box. For each support plane, all intersections with the bounding box and other support planes are given by lines, edges and vertices of the arrangement.

The initial intersections of the original input polygons are not considered. Thus increasing the `k` leads to a higher complexity of the partitioning, i.e., a higher number of facets and a higher number of volumes. For a certain `k` the partition can be considered to be complete and an increase in `k` will not further increase the complexity of the partition. +- `k`: unsigned int\n +The main parameter of this method is `k`, the maximum number of intersections that can occur for a polygon before its expansion stops. The initial intersections of the original input polygons are not considered. Thus increasing the `k` leads to a higher complexity of the partitioning, i.e., a higher number of facets and a higher number of volumes. For a certain `k` the partition can be considered to be complete and an increase in `k` will not further increase the complexity of the partition. A typical choice of `k` is in the range of 1 to 3. -- `reorient_bbox`: -The default bounding box of the partition is axis-aligned. Setting `reorient_bbox` to true aligns the x-axis of the bounding box with the direction of the largest variation in horizontal direction of the input data. +- `reorient_bbox`: boolean\n +The default bounding box of the partition is axis-aligned. Setting `reorient_bbox` to true aligns the x-axis of the bounding box with the direction of the largest variation in horizontal direction of the input data while maintaining the z-axis. -- `bbox_dilation_ratio`: +- `bbox_dilation_ratio`: FT\n By default the size bounding box of the input data is increased by 10% to avoid that input polygons are coplanar with the sides of the bounding box. +- `max_octree_node_size`: unsigned int\n +A kinetic partition is split into 8 subpartitions using an octree if the number of intersecting polygons is larger than specified. The default value is 40 polygons. + +- `max_octree_depth`: unsigned int\n +Limits the maximum depth of the octree decomposition. A limitation is necessary as arbitrary dense polygon configurations exist, e.g., a star. The default value is set to 3. + \section Ksp_result Result The kinetic partition can be accessed as a `LinearCellComplex` via `CGAL::Kinetic_shape_partition_3::get_linear_cell_complex()`. \subsection Ksp_examples Examples -The following example reads a set of polygons from a file and creates a kinetic partition. Increasing the `k` parameter to 2 or 3 leads to a more detailed kinetic partition. Increasing beyond 3 does not lead to more volumes as there are only few input polygons. +The following example reads a set of polygons from a file and creates a kinetic partition.

Choosing `k = 1` will cause the expansion of polygons to locally stop at the first intersection with another polygon and choosing `k` equal to the number of input polygons will lead to a full expansion of each polygon to the bounding box. \section Ksp_algorithm Algorithm -The first step of the method creates a plane arrangement between the support planes of the input polygons. The computation of a plane arrangement has O(\f$n^3\f$). To speed up the computation the input data can be decomposed into separate kinetic partitions using an octree.

The computation of a plane arrangement has \cgalBigO{n^3}. To speed up the computation the input data can be decomposed into separate kinetic partitions using an octree. The decomposition limits the expansion of an input polygon to octree nodes it initially intersects. The usage of an octree significantly speeds up the creation of the kinetic partition. However, it adds facets to the partition which originate from the octree and do not belong to an input polygon. The plane arrangement contains all points and lines of the intersections between the support planes and the bounding box. For each support plane, all intersections with the bounding box and other support planes are given by lines, edges and vertices of the arrangement. The kinetic partition created in the second step is a subset of faces of the arrangement depending on the `k` parameter. \cgalFigureBegin{Ksp_introductionfig,intersection_graph.png} diff --git a/Kinetic_shape_partition/examples/Kinetic_shape_partition/CMakeLists.txt b/Kinetic_shape_partition/examples/Kinetic_shape_partition/CMakeLists.txt index 4a4c0193a2b0..25690968e9da 100644 --- a/Kinetic_shape_partition/examples/Kinetic_shape_partition/CMakeLists.txt +++ b/Kinetic_shape_partition/examples/Kinetic_shape_partition/CMakeLists.txt @@ -20,7 +20,7 @@ if(Boost_FOUND) message(STATUS "Found Eigen") include(CGAL_Eigen_support) - set(targets kinetic_partition) + set(targets kinetic_partition kinetic_oriented kinetic_reconstruction) set(project_linked_libraries) set(project_compilation_definitions) From 506289defccc9386632f079a70e117aec414b43c Mon Sep 17 00:00:00 2001 From: Sven Oesau Date: Thu, 23 Nov 2023 16:24:26 +0100 Subject: [PATCH 470/512] merging of coplanar adjacent surfaces of reconstruction result from LCC insertion of ghost edges to convert polygons with holes into a single polygon aff_transformation_3 to reorient bbox is now epeck --- .../include/CGAL/KSP/debug.h | 47 +- .../include/CGAL/Kinetic_shape_partition_3.h | 29 +- .../CGAL/Kinetic_shape_reconstruction_3.h | 848 +++++++++++------- 3 files changed, 590 insertions(+), 334 deletions(-) diff --git a/Kinetic_shape_partition/include/CGAL/KSP/debug.h b/Kinetic_shape_partition/include/CGAL/KSP/debug.h index 8df8fd09b937..7bfdd5f897f0 100644 --- a/Kinetic_shape_partition/include/CGAL/KSP/debug.h +++ b/Kinetic_shape_partition/include/CGAL/KSP/debug.h @@ -108,12 +108,12 @@ void dump_2d_surface_mesh( using Mesh = CGAL::Surface_mesh;

It takes as input a set of non-coplanar convex polygons and partitions the bounding box of the input into polyhedra, where each polyhedron and its facets are convex. Each facet of the partition is part of the input polygons or an extension of them. The kinetic partition homogeneously expands each input polygon along its support plane until collisions occur between them. At each collision, their expansion may stop, they may restrict the propagation along an intersection line between two support planes or they may continue beyond the intersection line. The polygons are split at the beginning of the kinetic simulation and at each collision along the intersection line to be intersection-free. @@ -52,13 +52,13 @@ A kinetic partition is split into 8 subpartitions using an octree if the number Limits the maximum depth of the octree decomposition. A limitation is necessary as arbitrary dense polygon configurations exist, e.g., a star. The default value is set to 3. \section Ksp_result Result -The kinetic partition can be accessed as a `LinearCellComplex` via `CGAL::Kinetic_shape_partition_3::get_linear_cell_complex()`. +The kinetic partition can be accessed as a `LinearCellComplex` via `CGAL::Kinetic_space_partition_3::get_linear_cell_complex()`. \subsection Ksp_examples Examples The following example reads a set of polygons from a file and creates a kinetic partition. Increasing the `k` parameter to 2 or 3 leads to a more detailed kinetic partition. -\cgalExample{Kinetic_shape_partition/kinetic_partition.cpp} +\cgalExample{Kinetic_space_partition/kinetic_partition.cpp} */ diff --git a/Kinetic_shape_partition/doc/Kinetic_shape_partition/PackageDescription.txt b/Kinetic_space_partition/doc/Kinetic_space_partition/PackageDescription.txt similarity index 61% rename from Kinetic_shape_partition/doc/Kinetic_shape_partition/PackageDescription.txt rename to Kinetic_space_partition/doc/Kinetic_space_partition/PackageDescription.txt index 41eb7ee389b1..24fc0f33b6e3 100644 --- a/Kinetic_shape_partition/doc/Kinetic_shape_partition/PackageDescription.txt +++ b/Kinetic_space_partition/doc/Kinetic_space_partition/PackageDescription.txt @@ -1,17 +1,17 @@ /*! -\defgroup PkgKineticShapePartitionRef Kinetic Shape Partition Reference +\defgroup PkgKineticSpacePartitionRef Kinetic Space Partition Reference -\defgroup PkgKineticShapePartitionConcepts Concepts -\ingroup PkgKineticShapePartitionRef +\defgroup PkgKineticSpacePartitionConcepts Concepts +\ingroup PkgKineticSpacePartitionRef -\addtogroup PkgKineticShapePartitionRef -\cgalPkgDescriptionBegin{Kinetic Shape Partition, PkgKineticShapePartition} +\addtogroup PkgKineticSpacePartitionRef +\cgalPkgDescriptionBegin{Kinetic Space Partition, PkgKineticSpacePartition} \cgalPkgPicture{kinetic_logo.png} \cgalPkgSummaryBegin \cgalPkgAuthors{Sven Oesau and Florent Lafarge} -\cgalPkgDesc{This package implements kinetic shape partition.
