7 months ago I think I almost managed to do the above without any change to the existing code. The only issue is the BaseGeometryInterface has a reference to the intrinsic mesh in IntrinsicTriangulation that fails to be corrected (and I have no way to change without modifying the class(es)). Everything else I was about to restore I believe.
auto derived_ptr_sp
= dynamic_cast<geometrycentral::surface::SignpostIntrinsicTriangulation *>(
globals::generated_triangulation.get()
);
auto derived_ptr_ic
= dynamic_cast<geometrycentral::surface::IntegerCoordinatesIntrinsicTriangulation *>(
globals::generated_triangulation.get()
);
if (derived_ptr_sp != nullptr) { //Sign Post Realization
auto temp = std::make_unique<geometrycentral::surface::SignpostIntrinsicTriangulation>(
*globals::mesh_input, *globals::geometry_input
);
// Simulate loading Int. Mesh connectivity with a copy
temp->intrinsicMesh = globals::generated_triangulation->intrinsicMesh->copy();
temp->mesh = *temp->intrinsicMesh; // Illegal copy to a reference
// Edge Length Geometry members
temp->edgeLengths
= globals::generated_triangulation->edgeLengths.reinterpretTo(*temp->intrinsicMesh);
// Intrinsic Triangulation Members
temp->vertexLocations = globals::generated_triangulation->vertexLocations.reinterpretTo(
*temp->intrinsicMesh
);
// Sign Post Intrinsic Triangulation Members
temp->signpostAngle = derived_ptr_sp->signpostAngle.reinterpretTo(*temp->intrinsicMesh);
temp->edgeIsOriginal
= derived_ptr_sp->edgeIsOriginal.reinterpretTo(*temp->intrinsicMesh);
// Copy object for use
globals::generated_triangulation.reset();
globals::generated_triangulation = std::move(temp);
}
else { //Integer Coordinate Realization
auto temp = std::make_unique<
geometrycentral::surface::IntegerCoordinatesIntrinsicTriangulation>(
*globals::mesh_input, *globals::geometry_input
);
// Simulate loading Int. Mesh connectivity with a copy
temp->intrinsicMesh = globals::generated_triangulation->intrinsicMesh->copy();
temp->mesh = *temp->intrinsicMesh; // Illegal copy to a reference
// Edge Length Geometry members
temp->edgeLengths
= globals::generated_triangulation->edgeLengths.reinterpretTo(*temp->intrinsicMesh);
// Intrinsic Triangulation Members
temp->vertexLocations = globals::generated_triangulation->vertexLocations.reinterpretTo(
*temp->intrinsicMesh
);
// Integer Coordinates Intrinsic Triangulation Members
new (&temp->normalCoordinates)
geometrycentral::surface::NormalCoordinates(*temp->intrinsicMesh);
temp->normalCoordinates.edgeCoords
= derived_ptr_ic->normalCoordinates.edgeCoords.reinterpretTo(*temp->intrinsicMesh);
temp->normalCoordinates.roundabouts
= derived_ptr_ic->normalCoordinates.roundabouts.reinterpretTo(*temp->intrinsicMesh);
temp->normalCoordinates.roundaboutDegrees
= derived_ptr_ic->normalCoordinates.roundaboutDegrees.reinterpretTo(
*temp->intrinsicMesh
);
// Copy object for use
globals::generated_triangulation.reset();
globals::generated_triangulation = std::move(temp);
}
Hey,
My application requires saving the mesh connectivity, mesh geometry, and mesh data for intrinsic triangulation on top of extrinsic input meshes. I tried using RichSurfaceMeshData and creating the intrinsic geometry elements and properties (ply file format); however, there is no way (at least I can see) of restoring the intrinsic triangulation alongside the extrinsic data without saving the history of how the triangulation was formed. My intent was to save a ply with both the input extrinsic structure and the input triangulation(s). Is there any future work for improving the IO of the GC structures?
