Ox Oy Oz

Position of the volume center in the global coordinate system of the mock-up

Ix Iy Iz

Position of the volume center in the global coordinate system of the mock-up

Jx Jy Jz

Y direction of the volume in the global coordinate system of the mock-up

Xwidth Ywidth Zwidth

Size of the volume along X, Y, Z direction

3 5 2

Sampling of the volume along X, Y, Z direction

0 1 2

Ltype Lnb Lp

• Ltype: Type of layer separation

  0 - None

  1 - by source

  2 - by face

• Lnb: Number of layers

• Lp: Power for each layer

  (expressed in the same unit as defined in line 2)

  Note: In case of separation by face, the power is not used and each layer gets a value of 1.

Blank line

All Sources / S.1:5859 / |Solid:38

Layer name

• No separation : All Sources
• Separation by source: Source name (S.1:5859 in the example)
• Separation by face: Name of faces or bodies selected (|Solid:38 in the example)

D(i,jk): energy density at pixel i (x direction), j (y direction), k (z direction)

D(0,1,0) D(1,1,0) ... D(Xsamp -1,1,0) D(Xsamp,1,0)

Block describing one Z value "Z0"

For one block:

• Values in a row parse data along X direction
• Values in a column parse data along Y direction

All values of the block correspond to one Z value
