Detailed Description

Data holding a geometric structure composed of points, lines, triangles, quads or polygons.

It is the new structure that represent mesh in fw4spl. For the moment, this new structure is available to register mesh with triangle cells, with quad cells or with triangle and quad cells. Peharps, in future work other cell type will be available (ex: POLYGON)

This structure contains some information stock in fwData::Array
An array (m_points) which contains point coord (x,y,z)
An array (m_cellTypes) which contains cell type (TRIAN or QUAD for the moment)
An array (m_cellData) which contains point indexes in m_points used to create cells, 3 indexes are necessary to create a triangle cell, 4 for quad cell.
An array (m_cellDataOffsets) which contains indexes relative to m_cellData, to retrieve the first point necessary to the cell creation.
Example :
m_points.size = number of mesh points * 3
m_points = [ x0, y0, z0, x1, y1, z1, x2, y2, z2, x3, y3, z3, ... ]
m_cellTypes.size = number of mesh cells
m_cellTypes = [TRIANGLE, TRIANGLE, QUAD, QUAD, TRIANGLE ... ]
m_cellDataOffsets.size = number of mesh cells
m_cellDataOffsets = [0, 3, 6, 10, 14, ... ] (offset shifting in m_cellData = +3 if triangle cell rr +4 if quad cell)
number of mesh cells * 3 (if only triangle cell) < m_cellData.size < number of mesh cells * 4 (if only quad cell)
m_cellData = [0, 1, 2, 0, 1, 3, 0, 1, 3, 5... ] ( correspond to point id )
Get the points coordinates of the third cell
m_cellTypes[2] => cell type = QUAD
m_cellDataOffsets[2] => index in m_cellData of cell definition = 6
index of p1 = m_cellData[6] = 0
index of p2 = m_cellData[6+1] = 1
index of p3 = m_cellData[6+2] = 3
index of p4 = m_cellData[6+3] = 5
p1 = [ x0=m_points[0] y0 z0 ] ( 0 * 3 = 0 )
p2 = [ x1=m_points[3] y1 z1 ] ( 1 * 3 = 3 )
p3 = [ x3=m_points[9] y3 z3 ] ( 3 * 3 = 9 )
p4 = [ x5=m_points[15] y5 z5 ] ( 5 * 3 = 15 )
We have another array to stock normal by points, normal by edges, color by points or color by cells, to short :
Normal arrays contains normal vector (x,y,z)
normals.size = number of mesh points (respc cells) * 3
normals = [ x0, y0, z0, x1, y1, z1, x2, y2, z2, x3, y3, z3, ... ]
Color arrays contains RGB or RGBA colors ( check the number of components 3 or 4 of array )
colors.size = number of mesh points (respc cells) * 3 (respc 4)
colors = [ r0, g0, b0, r1, g1, b1, ... ]
or colors = [ r0, g0, b0, a0, r1, g1, b1, a1, ... ]

Member Function Documentation

bool fwData::Mesh::adjustAllocatedMemory ( )

Adjust mesh memory usage.

The array (points, cell-types, cell-data, cell-data-offsets, and if they exists point-colors/normals and cell-colors/normals) will be resized according to the number of points and cells of the mesh (they may have been defined before adjusting by setNumberOfPoints or setNumberOfCells). Arrays in array-map are not impacted by this method.

Returns: true if memory usage changed

::fwData::Array::sptr fwData::Mesh::m_cellData

protected

Cell data array : 1-components 1-dimension uint64 array, size = m_cellsDataSize.

Contains cell data : cell points ids are contiguously stored regardless of the cell type. Size depends of cell type. If we have only TRIANGLE type, size = m_nbCells x 3.

This array contains point indexes (index in m_points) : [ TRIAN_ID1, TRIAN_ID2, TRIAN_ID3, QUAD_ID1, QUAD_ID2, QUAD_ID3, QUAD_ID4, ... ]
