New CullPyr

• Selects a portion of a pyramid, based on data values
• Uses data from
  • base lattice, or
  • top layer lattice, if present new
• Can select values inside or outside range

New ClipPyr

• Cuts pyramid with arbitrary oriented plane
• Can select pyramid elements either side of the plane, or at the intersection with the plane
• Can select pyramid elements either side of the plane, or at the intersection with the plane
• Preserves data at higher (non-base) levels new

Example

Reservoir data

• Simulation of oil transport through permeable medium
• Each cell has a permeability value
• CullPyr used to select cells inside or outside a range of permeability values
• PyrToGeom creates geometry and colours it according to cell data
• DrawText creates caption which dynamically updates as range changes

Lines of force

• Measurement of forces between spheres in an amorphous sphere pack
• Data stored as a pyramid
  • sphere coords in base lattice
  • forces in lattice at layer[0]
• CullPyr used to select lines inside or outside a range of force values
• PyrToGeom creates geometry and colours it according to line data

FE data (4)

• FE calculation in cylinder
• Calculates mass fraction in elements
• ClipPyr used to cut into object and reveal internal structure
• PyrToGeom creates geometry and colours it according to mass fraction values
