[Paraview-developers] different types of blocks , all share the same points

[RIVERA ROLDAN, Jorge Orlando]

Dear  PV Community,

I am writing a  reader  and  I can't think of a optimal approach.


I have a  point cloud , this is one  entity. The connectivity is on this points ,  but the elements are separated into different types or and sets.  I would like to have these element sets independently , so I can turn off /turn on .   I was thinking in using a MultiBlock ,     but  each grid should  have its own points, right?  However, all  grids/blocks share the same points.

My data layout  looks like this:

POINTS:
Point 0:  X0  Y0  Z0
Point 1: X1 Y1  Z1
Point 2: X2  Y2  Z2
...
Point n: Xn Yn  Zn
ELEMENTS  TYPE=VTK_QUAD
ELE0:  P0 P1 P3 P4
ELE1 : P5 P6 P7 P8
.....
ELEMENTS  TYPE=VTK_TETRA
ELE2:   P9 P10 P11 P12
ELE3:   P13 P14...
...
ELEMNTS TYPE=VTK_HEXAHEDRON
ELE4 :  P15 P16 P17 P18 P0 P1 P2 P3 P4
.....
ELEN :  P19 P20 O21 ... .... Pn


As you can see the natural way to separate all different  element types is by using the MB , but as already mentioned the points are  shared by al blocks

Many thanks in advance

Cheers


Orlando
