Detailed Description

Extracts material fragments from multi-block vtkRectilinearGrid datasets based on the selected volume fraction array(s) and a fraction isovalue and integrates the associated attributes.

Given one or multiple vtkRectilinearGrid datasets with one or multiple volume fraction arrays (representing some materials) and possibly other attributes (like pressure, density, and et al) as the cell data, this filter extracts fragments from the dual grids (with the aforementioned values as the point data) based on the (at least one) selected fraction array(s) in combination with a specified fraction value and integrates the attributes (e.g., volume, pressure, density) across the surface of each fragment. Each material, made up of one or multiple disconnected fragments, is exported to the output vtkMultiBlockDataSet as a single block that is a vtkPolyData storing the exterior polygons of the fragment (s) and the associated cell data attributes as the integrated result (of the fragment) in terms of the volume, pressure, density, and et al.

This filter differs from a closely related filter vtkGridConnectivity in that the former extracts fragments at a sub-cell resolution to create relatively smooth surfaces while the latter works at the cell granularity (a whole cell is taken as either inside or outside a fragment) to cause staircasing artifacts. In fact, an extended 256-entry marching cubes LUT is designed for generating cube faces (either truncated by iso-lines or not) in addition to iso-triangles. These two kinds of polygons in combination represent the surface(s) of the greater-than-isovalue sub- volume(s) extracted in a cube.

vtkRectilinearGridConnectivity performs fragments extraction using a three-level mechanism, i.e., intra-process intra-block, intra-process inter-block, and inter-process in increasing order, with the fragments extracted (in the form of polygons stored as a vtkPolyData) at a lower level submitted to its upper level for further extraction (specifically by combining multiple disconnected fragments into a single one wherever possible). Since a fragment is represented by means of its exterior faces / polygons, extracting fragments turns into the task of detecting and removing internal faces (an internal face is the one shared by two sub- volumes or fragments) in a way of combining the associated sub-volumes or fragments. For the fragemnts extraction conducted at any level, the polygons of the input (e.g., greater-than-isovalue sub-volumes resulting from marching cubes for the lowest level extraction) are pushed to a face hash (that accepts the three smallest point Ids of a polygon: triangle, quad, or pentagon) on a per sub-volume or fragment basis. Once the face hash detects an internal face, an entry is added to an equivalence set (by means of class vtkEquivalenceSet) to correlate the two fragment Ids that are attached to the two associated sub-volumes or fragments' polygons. After resolving the equivalence set, each face that remains in the face hash (internal faces are masked as invalid) is updated with a resolved fragment Id. In this way the original complete polygons (triangles, quads, pentagons) pointed to by the remaining hashed faces with the same resolved fragment Id are retrieved from the input vtkPolyData and hence combined by means of the same fragemnt Id.

protected

Given numBlcks vtkRectilinearGrid blocks with point data attributes (i.e.,the dual grid version of the original blocks with cell data attributes), the bounding box (boundBox) covering these blocks, and a selected volume fraction array specified by the material index (partIndx), this function extracts fragments based on this volume fraction array and exports the result to a vtkPolyData (polyData).

Given a data block index (blockIdx) and a vtkPolyData (plyHedra) storing the polygons of the greater-than-isovalue sub-volumes (or polyhedra) that are extracted from the block, this function pushes the polygons on a per sub-volume basis to the face hash (the sub-volume Ids are used to group polygons into sub-volumes).

For each internal polygon / face shared by two sub-volumes, an entry is added to the (intra-process intra-block) equivalence set to associate the fragment Ids assigned to the two sub- volumes' polygons.

Given the index of the data block (blockIdx), the vtkPolyData (plyHedra) storing the polygons / faces of the greater-than-isovalue sub-volumes (or polyhedra) extracted from this block via marching cubes, and a global (intra-process inter-block) point locator, the function extracts fragments from this block by initializing the face hash with the raw polygons extracted from the block (via marching cubes), pushing these polygons to the face hash on a per sub-volume basis, detecting internal faces or polygons, registering faces to the intra-process intra-block equivalence set by the intermediate fragment Id, resolving the equivalence set, updating the fragment Id of each polygon, and integrating cell data attributes based on the fragment Id, grouping / re-arranging the 'valid' faces (as opposed to those removed internal faces) in the face hash by the fragment Id (to construct macro-volumes), accessing the full version of each valid face from the original polyhedra, and attaching the fragment Id as well as other integrated cell data attributes to each cell in the output vtkPolyData data (polygons) where each point is assigned with a global (intra-process inter-block) Id (via a global point locator gPtIdGen) used for subsequent combination of fragments extracted from multiple blocks.

Argument maxFSize returns the maximum number of faces a macro-volume (combination of sub-volumes) may contain in a block.

protected

Given a number (numPolys) of vtkPolyData objects (plyDatas) storing the fragments extracted from the multiple data blocks, this function inits the face hash (with the maximum global inter-block point Id: a point data attribute attached to each point of these vtkPolyData objects) that is used to combine these intermediate fragments.

◆ AddPolygonsToFaceHash() [2/2]

void vtkRectilinearGridConnectivity::AddPolygonsToFaceHash	(	vtkPolyData **	plyDatas,

protected

Given a number (numPolys) of vtkPolyData objects (plyDatas) storing the initial fragments (macro-volumes — combination of greater-than-isovalue sub-volumes) extracted from multiple blocks and an array of values (maxFsize) storing the maximum number of faces that a macro-volume may contain in each block (used to allocate appropriate memory for buffering the polygons of a macro-volume), this function pushes these polygons on a per macro-volume basis to the face hash (fragment Ids are used to group polygons to macro-volumes), detects internal faces / polygons, and then registers polygons to the (intra-process inter-block) equivalence set by the intermediate fragment Id.

For each internal polygon / face shared by two macro-volumes, an entry is added to the equivalence set to associate the fragment Ids assigned to the two macro-volumes' polygons.

		unsigned char	partIndx,
		vtkPolyData *	polyData
	)

protected

With the intra-process inter-block equivalence set resolved, intra-process inter-block fragment Ids resolved, and cell data attributes integrated by the fragment Id, this function retrieves the face hash for the 'valid' faces (as opposed to those removed internal faces), accesses their full version from the vtkPolyData objects ('surfaces') that store the polygons of intermediate fragments extracted from multiple ('numSurfs') data blocks, and exports these complete yet 'valid' polygons to the output vtkPolyData ('polyData') while attaching the index of the material (partIndx, i.e.

the volume fraction array used to extract fragments) to each polygon as a cell data attribute. In a word, this function exports a combined version of the fragments extracted from multiple blocks assigned to a single process.

◆ CreateInterProcessPolygons()

	)

protected

Given the vtkPolyData (fragPoly) storing the fragments extracted from a single process (assigned with either one block or multiple blocks), this function groups / re-arranges the polygons by the (intra-process inter- block) fragment Id, determines the maximum number (maxFsize) of polygons (belonging to a fragment) with the same fragment Id, and exports the re- arranged polygons with the associated fragment Ids and all integrated cell data attributes to the output inter-process vtkPolyData (procPoly) where each point is assigned with a global inter-process point Id (through a global point locator 'gPtIdGen') as the point data attribute used later for combining the fragments across multiple processes.

◆ AddInterProcessPolygonsToFaceHash()

void vtkRectilinearGridConnectivity::AddInterProcessPolygonsToFaceHash	(	vtkPolyData **	procPlys,
		int *	maxFsize,
		int	numProcs
	)

protected

Given a number (numProcs) of vtkPolyData objects (procPlys) storing the (initial) fragments extracted from multiple processes and an array of values (maxFsize) storing the maximum number of faces that an initial fragment may contain on each process (used to allocate appropriate memory for buffering the polygons of an initial fragment), this function pushes these polygons to the face hash on a per fragment basis (the fragment Ids are used to group polygons into initial fragments), detects internal faces / polygons, and registers polygons to the inter-process equivalence set by the intermediate fragment Id.

For each internal polygon / face shared by two initial fragments, an entry is added to the equivalence set in a way to associate the fragment Ids assigned to the two initial fragments' polygons. Note each face in the face hash is assigned with a process Id that is used later to retrieve the source vtkPolyData for the target complete polygon if the face remains in the face hash after removing internal faces.

◆ GenerateOutputFromMultiProcesses()

void vtkRectilinearGridConnectivity::GenerateOutputFromMultiProcesses	(	vtkPolyData **	procPlys,
		int	numProcs,
		unsigned char	partIndx,
		vtkPolyData *	polyData
	)

protected

With the inter-process equivalence set resolved, inter-process fragment Ids resolved, and cell data attributes integrated by the fragment Id, this function retrieves the face hash for the 'valid' faces (as opposed to the removed internal faces), accesses their complete version (according to the information stored in the face) from the vtkPolyData objects (procPlys) that store the polygons of the fragments extracted from multiple (numProcs) processes, and exports these complete 'valid' polygons to the output vtkPolyData (polyData) while attaching the index of the material (partIndx, corresponding to the volume fraction array used to extract the fragments) to each polygon as a cell data attribute.

In a word, this function exports a combined version of the fragments extracted from multiple processes (of which each is assigned with either one block or multiple blocks).
