Step.3: this is the tricky part, I had to isolate the perimeter boundary meshes of the low-res mesh that was not within the attractor range, so this meshes can be post processed. Then this meshes can be used as boundary stitching limit which works as resolution threshold between the low res-mesh and high res-mesh, this boundary is capable to detect the level of resolution of the high-res mesh so it can re-topologies itself to achieve the mesh resolution transition, when this is done then you will have a fully join and welded the meshes (final result fully water tide).

Step.1: first I created a three-dimensional scalar field, then using attractor logics I cull the voxels within the specified range, then the coincident faces within the remaining voxels are cull and the remaining meshes are join and welded creating a single mesh object.

Step.2: creating a similar attractor logic I can separate in two groups the meshes that are within the specified range from the ones that are not within the specified range, then I process the meshes within the attractor range Weaverbird´s Laplacian smoothing/volume decrease with fix boundary condition and further Catmull Clark sub division (naked edge fix, level.1).

Thanks Angel,

this is part of the of my computational courses sessions for my students at the MArch UDII_Bartlett UCL.

Super nice research study.
