From 80893e96b66255599f3dd006b90ffb022294346c Mon Sep 17 00:00:00 2001 From: Andrea Iob Date: Mon, 2 Oct 2023 17:50:36 +0200 Subject: [PATCH] levelset: rework overall design The main purpose of the rework is to reduce the memory footprint of the levelset. To achieve this goal, the values computed by the levelset are stored in separate caches. Each cache can be enabled separately form the other and can operate in one of the following modes: values can be cached as their are evaluated; values can be pre-computed inside the narrow band; values can be pre-computed on the whole domain. When no caches are enabled, the only memory used by the levelset is the memory that each object uses to store its own information (for example the object that evaluates the levelset of a segmentation stored information about the normals of the segmentation). When no cached are enabled, the evaluation of the levelset is thread safe and this allows to use the levelset object inside parallel OpenMP regions. --- examples/RBF_example_00001.cpp | 9 +- src/levelset/bitpit_levelset.hpp | 3 +- src/levelset/levelSet.cpp | 693 ++-- src/levelset/levelSet.hpp | 78 +- src/levelset/levelSet.tpp | 73 + src/levelset/levelSetBooleanObject.hpp | 31 +- src/levelset/levelSetBooleanObject.tpp | 341 +- src/levelset/levelSetBoundedObject.hpp | 50 - src/levelset/levelSetCachedObject.cpp | 538 --- src/levelset/levelSetCachedObject.hpp | 279 -- src/levelset/levelSetCachedObject.tpp | 438 --- src/levelset/levelSetCartesianKernel.hpp | 3 - src/levelset/levelSetCommon.hpp | 83 +- src/levelset/levelSetComplementObject.hpp | 17 +- src/levelset/levelSetComplementObject.tpp | 169 +- src/levelset/levelSetKernel.cpp | 78 +- src/levelset/levelSetKernel.hpp | 19 +- src/levelset/levelSetMaskObject.cpp | 195 +- src/levelset/levelSetMaskObject.hpp | 21 +- src/levelset/levelSetMaskObject.tpp | 226 -- src/levelset/levelSetObject.cpp | 3387 ++++++++++++++--- src/levelset/levelSetObject.hpp | 266 +- src/levelset/levelSetObject.tpp | 328 ++ src/levelset/levelSetObjectFactory.hpp | 66 - src/levelset/levelSetObjectFactory.tpp | 165 - src/levelset/levelSetOctreeKernel.hpp | 3 - src/levelset/levelSetProxyObject.hpp | 34 +- src/levelset/levelSetProxyObject.tpp | 206 +- src/levelset/levelSetSegmentationObject.cpp | 2332 +++++++++--- src/levelset/levelSetSegmentationObject.hpp | 347 +- src/levelset/levelSetSegmentationObject.tpp | 856 ----- src/levelset/levelSetSignPropagator.cpp | 657 ---- src/levelset/levelSetSignPropagator.hpp | 68 - src/levelset/levelSetSignedObject.cpp | 238 -- src/levelset/levelSetSignedObject.hpp | 88 - src/levelset/levelSetStorage.cpp | 525 --- src/levelset/levelSetStorage.hpp | 402 -- src/levelset/levelSetStorage.tpp | 926 ----- src/levelset/levelSetUnstructuredKernel.hpp | 3 - .../integration_tests/levelset/CMakeLists.txt | 1 + .../levelset/test_levelset_00001.cpp | 22 +- .../levelset/test_levelset_00002.cpp | 37 +- .../levelset/test_levelset_00003.cpp | 86 +- .../levelset/test_levelset_00004.cpp | 47 +- .../levelset/test_levelset_00005.cpp | 45 +- .../levelset/test_levelset_00006.cpp | 6 +- .../levelset/test_levelset_00007.cpp | 122 +- .../levelset/test_levelset_00008.cpp | 136 +- .../levelset/test_levelset_00009.cpp | 146 +- .../levelset/test_levelset_00010.cpp | 850 +++++ .../levelset/test_levelset_parallel_00001.cpp | 54 +- .../levelset/test_levelset_parallel_00002.cpp | 32 +- .../levelset/test_levelset_parallel_00003.cpp | 24 +- 53 files changed, 8071 insertions(+), 7778 deletions(-) delete mode 100644 src/levelset/levelSetBoundedObject.hpp delete mode 100644 src/levelset/levelSetCachedObject.cpp delete mode 100644 src/levelset/levelSetCachedObject.hpp delete mode 100644 src/levelset/levelSetCachedObject.tpp delete mode 100644 src/levelset/levelSetMaskObject.tpp create mode 100644 src/levelset/levelSetObject.tpp delete mode 100644 src/levelset/levelSetObjectFactory.hpp delete mode 100644 src/levelset/levelSetObjectFactory.tpp delete mode 100644 src/levelset/levelSetSegmentationObject.tpp delete mode 100644 src/levelset/levelSetSignPropagator.cpp delete mode 100644 src/levelset/levelSetSignPropagator.hpp delete mode 100644 src/levelset/levelSetSignedObject.cpp delete mode 100644 src/levelset/levelSetSignedObject.hpp delete mode 100644 src/levelset/levelSetStorage.cpp delete mode 100644 src/levelset/levelSetStorage.hpp delete mode 100644 src/levelset/levelSetStorage.tpp create mode 100644 test/integration_tests/levelset/test_levelset_00010.cpp diff --git a/examples/RBF_example_00001.cpp b/examples/RBF_example_00001.cpp index 8baa1c36e9..1817458450 100644 --- a/examples/RBF_example_00001.cpp +++ b/examples/RBF_example_00001.cpp @@ -236,15 +236,14 @@ void run(std::string filename, // Set levelset configuration bitpit::LevelSet levelset; + levelset.setPropagateSign(true); + levelset.setSizeNarrowBand(sqrt(3.0) * h); levelset.setMesh(&mesh); + int id0 = levelset.addObject(std::move(STL0), 0); const bitpit::LevelSetObject &object0 = levelset.getObject(id0); - std::vector ids; levelset.getObject(id0).enableVTKOutput(bitpit::LevelSetWriteField::VALUE); - levelset.setPropagateSign(true); - levelset.setSizeNarrowBand(sqrt(3.0) * h); - // Compute the levelset - levelset.compute(id0); + // Write levelset information mesh.write(); bitpit::log::cout() << "Computed levelset within the narrow band...
