[Paraview] filter to read in 3D cell data

[Felipe Bordeu]

Hi,

I use xdmf to wrap the binary data. (spacing, offset, size, ...)


for  example  Engine.xmdf:

<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf Version="2.0">
<Domain>
<Grid Name="mesh" GridType="Uniform">
<Topology TopologyType="3DCORECTMESH" NumberOfElements="128 256 256"/>
<Geometry GeometryType="ORIGIN_DXDYDZ">
<DataItem Format="XML" NumberType="float" Dimensions="3">
          0.0 0.0 0.0
</DataItem>
<DataItem Format="XML"  NumberType="float" Dimensions="3">
          1.0 1.0 1.0
</DataItem>
</Geometry>
<Attribute Name="myfielddata" Center="Cell" AttributeType="Scalar">
<DataItem Format="Binary" NumberType="UChar" Dimensions="128 256 256" 
Seek="0">
engine_unsignedchar_255_255_127.raw
</DataItem>
</Attribute>
</Grid>
</Domain>
</Xdmf>

the file engine_unsignedchar_255_255_127.raw contains all the data in 
binary.

more information about this format in
