% (by Tim Lueth, VLFL-Lib, 2017-AUG-01 as class: SURFACES)
%
% ATTENTION: SGbool4 is the same fnctn as SGbool3, but much faster. It
% uses the - now public - fnctns
% SGintersectFacetPoints and VLFLinsertFacetPoints which were private in
% SGbool3. It has a more clear structure, but has exactly the same
% algorith for face assignment. In addition it shows all four possible
% results of SGbool for two solids. Use CSGsample for testing.
% Nevertheless, it should be clear that there are limitations even of
% closed surface models with SGbool3 and SGBool4:
% 1. Never have identical points in both surfaces
% 2. Never have identical lines in both surfaces
% 3. Never have indentical surface planes in both surfaces
% 4. Never have an overlap of enclosed "holes" => unmotivated surfaces
% If there is a risc, use SGgrow to grow before substraction or addition
% by 1e-4
% It is possible to remove those problems one day by cutting tetrahedrons
% instead of triangles
% A => A without B
% B => B without A

pdemodelofSG(SG,h,e)- creates a pde model from a solid geometry

% (by Tim Lueth, VLFL-Lib, 2017-JUL-19 as class: FEM/PDE)
%
% This fnctn creates a pde model from a given solid. The pde models are
% typically loaded from a STL File similar to Simccape Multibody.
% Therefor this fnctn writes a temp solid and reads it afterwards.
%
% A pde model consists of a tetrahedral cross-linking (there are several
% possibilities for the fnctn generateMesh), while one, two or
% three-dimensional propagation of effects can be specified (line
% problems, surface deformation, volume deformation) The standard FEM
% equation will be specified. For these effects, the equilibrium
% condition formula can be selected or the parameters for the standard
% FEM equation specified. Subsequently, surfaces / introduction points
% with state specifications are given and surfaces / initiation point are
% given the effects of the action.
%
% ATTENTION: models are objects and modified by MATLAB fnctn with calls
% by reference! It means the models are modified by a call even the
% models are not an output parameter! The repeated call of
% applyBoundaryCondition(model, ....
% will add at each time conditions to the model even if the conditions
% are all the same!
%
% *MOTIVATION FOR THE PDE fnctns IN SG-LIB* The Partial Diffential
% Equation Toolbox (pde) contains some features that are helpful for the
% basic processing of solids. However, some of this feature does not have
% direct access, such as patching. Since the user can only access the
% faces assignment via a graphical representation, the SG-Lib has to
% implement a similar faces seperation. The same applies to the
% production of the mesh tesselation. (Status of: 2018-02-28)

% (by Tim Lueth, VLFL-Lib, 2017-JUL-16 as class: SURFACES)
%
% *Hollow structures from closed solid surface models:* For all closed
% surfaces it is easy: Create a grown/shrinked copy of the solid with a
% defined wall thickness. For grown copies (shells), invert afterwards
% the inner/original faces of the solid. for shrinked copies (hollow
% solid walls), invert afterwards the inner/shrinked faces of the copy.
% Both surfaces together are the final hollow solid.
% ATTENTION: For a closed surface for most of the 3D printing processes
% it makes no sense to convert solids into shell structures since the
% material in the shells is not removable. There is no weight advantage!
% The vertices are sorted: VL=[ORG;COPY]; The facets are sorted
% FL=[ORG;COPY]
%
% *Solid structures from open free form surfaces:* In case of open
% surfaces that do not represent a solid, this fnctn will create also
% create a shrinked or grown copy and calculates in addition the facets
% that link the corresponding walls.
% The vertices are sorted: VL=[ORG;COPY]; The facets are sorted
% FL=[ORG;COPY,WALL]
%
% *PRINCIPLE* Since the normal vector of all vertices is known, the grow
% procedure will move this vertices along the normal vector. For an
% isolated surface the normal vector can also be calculated, but in case
% of features edges or features surfaces, the normal vector of the edge
% contour cannot be calculated isolated from other attached surfaces.
%
% *ERROR CONDITIONS* In case that a isolated surface is processed, the
% grow fnctn will not work as expected. This fnctn is for processing
% connected surfaces of a closed solid only

neighborsAngleSurface(NAL,NBL,alpha,fi) % neighborsAngleSurface(NAL,NBL,alpha,fi) - returns connected facets with respect to a feature angle
% (by Tim Lueth, VLFL-Lib, 2017-JUL-05 as class: SURFACES)
%
% The required parameter NAL,NBL are calculated using TR3neighborsAngle.
% Since TR3neighborsAngle can be slow, the fnctns are separated to
% accelerate the repeatet use of neighborsAngleSurface.
%
% (Status of: 2017-07-05)
%
% Introduced first in SolidGeometry 4.0
%
% See also: TR3neighborsAngle
%
% [fa,FCL]=neighborsAngleSurface(NAL,NBL,alpha,fi)
% === INPUT PARAMETERS ===
% NAL: =TR3neighborsAngle(TR3)
% NBL: =neighbors(TR3), also delivered by [NAL,NBL]=TR3neighborsAngle(TR3)
% alpha: feature angle
% fi: starting facet index (can be several)
% === OUTPUT RESULTS ======
% fa: facet index with respect to NAL,NBL of (TR3)
% FCL: Facet connection list; optional
%
% EXAMPLE:
% SG=SGsample(25);
% [NAL,NBL]=TR3neighborsAngle(SG); fi=neighborsAngleSurface(NAL,NBL,1,22);
% VLFLplot(SG.VL,SG.FL(fi,:))

TR3featureEdges(TR3,alpha)- returns feature edge List plus edge attached facets
TR3featureEdges(TR3,alpha) % TR3featureEdges(TR3,alpha) - returns feature edge List plus edge attached facets
% (by Tim Lueth, VLFL-Lib, 2017-JUL-05 as class: SURFACES)
%
% Auxiliary fnctn as starting point:
% Simply calls featureEdges. It is not using edgeAttachments but an own
% solution
% (Status of: 2017-07-05)
%
% Introduced first in SolidGeometry 4.0
%
% [EL,Fi]=TR3featureEdges(TR3,alpha)
% === INPUT PARAMETERS ===
% TR3: Triangulation
% alpha: feature edge angle
% === OUTPUT RESULTS ======
% EL: Feature Edge List
% Fi: Index of TR3.ConnectivityList of attached facets
%
% EXAMPLE:
% TR3featureEdges(SGsample(25),1)

TR3neighborsAngle(TR3)- returns the angle difference between a facet an its neigbors
TR3neighborsAngle(TR3) % TR3neighborsAngle(TR3) - returns the angle difference between a facet an its neigbors
% (by Tim Lueth, Video-Lib, 2017-JUL-04 as class: SURFACES)
%
% Calculated the difference angle between a surface and its neighbor
% surfaces.
% Typically used in combination with/to create the input for
% fnctn neighborsAngleSurface (Status of: 2017-07-05)
%
% Introduced first in SolidGeometry 4.0
%
% See also: neighborsAngleSurface, diffangle
%
% [NAL,NBL,FNL]=TR3neighborsAngle(TR3)
% === INPUT PARAMETERS ===
% TR3: Triangulation or SG
% === OUTPUT RESULTS ======
% NAL: Facet Normal Angle List wrt to NBL
% NBL: Neighbor List = neighbors(TR3)
% FNL: Facet normal List = faceNormal(TR3)

loadweb (mname,overwr,urlp)- loads mat files from an web url
loadweb (mname,overwr,urlp) % loadweb (mname,overwr,urlp) - loads mat files from an web url
% (by Tim Lueth, VLFL-Lib, 2017-JUL-03 as class: AUXILIARY PROCEDURES)
%
% This fnctn reduces the size of the SG-Lib Toolbox since the '.mat'
% files and the directories can be downloaded once into the user
% directory.
% if parameter overwr=false; the filename will be "downloaded_mname"
% if parameter overwr=true; the filename will be "mname"
% Try:
% 'AAruffo_surf.mat' (3.6 MByte) = Geometry of some human arms
% 'JACO_robot.mat' (6.1 MByte) = Geometry of the JACO robot structure
% 'AIM_SGrobot.mat' (0.1 MByte)
% 'AIM_Patientmodel.mat' ( 5MByte) = 216 x 216 x 26 Slices of a Human
% Head CT Voxel model
% 'ModulKegelradwelle_1.mat' (0.2 MByte)
% 'NDI_STLs.mat' (0.1 MByte) = Geometry of the NDI mounting post for
% spheres (Status of: 2017-07-26)
%
% Introduced first in SolidGeometry 4.0
%
% See also: load, webread
%
% loadweb(mname,[overwr,urlp])
% === INPUT PARAMETERS ===
% mname: name and extension of the file
% overwr: true=overwrite; default is false.
% urlp: web path; default is
% 'https://www.mec.ed.tum.de/fileadmin/w00cbp/mimed/Matlab_Toolboxes/'
%
% EXAMPLE:
% loadweb('JACO_robot.mat') % loads the downloaded file
% loadweb('JACO_robot.mat',true) % replaces the original file by the
% downloaded file
