SimpleGeo3.0 & the next release 3.1

Plugins2.0 & the next release 2.1

simplegeo 3 0
SimpleGeo 3.0
  • Importer:
    • Cards (e.g. ASSIGNMAT, BIASING) can now mix numbers and names
    • Full support of preprocessor up to arbitrary recursion depth
    • Name recognition is case insensitive – less error prone!
    • Named ranges are not supported!
  • Exporter:
    • MCNP(X), automatic conversion of names by SG!
    • More 3D formats (3DS, PLY, PBRT, STL, etc.)
simplegeo 3 01
SimpleGeo 3.0
  • Some new macros:
    • Conversion of names tonumbers
    • Conversion of numbers to names
  • Auto-save function
  • Calculation of surface areas(via Node-Info in the context menu)
  • Click and zoom

simplegeo 3 1
SimpleGeo 3.1

Major features likely to be included in V3.1

  • Mathematical expressions supported in numeric property fieldsand in the normalization in DaVis3D.
  • Improved renderer (e.g. new render mode hard contours)
  • Splitting wizard (automatic generation of split regions)

SimpleGeo 3.1
  • A lot of users are migrating to Windows Vista:
    • V3.1 fully Vista compliant
    • Heavily optimized for Vista:
      • New proprietary memory management
      • SSE2 instruction set used
      • Parallelization currently evaluated (very early test phase)

  • How to do it:
  • Link a specialized MGDRAW.F to FLUKA
  • Add a USERDUMP card
  • 3. Process the binary with the supplied PipsiCAD program under Linux
  • 4. Load the result with the PipsiCAD3D plugin & press play
simplegeo davis3d

Available in DaVis3D 2.5:

  • Added support for RZ and R-Phi-Z meshes with arbitrary resolution.
  • (XYZ is still the fastest topology!)
  • Calculate average + errors of several ASCII USRBIN
  • result files
  • Several meshes (also with different resolutions and/or spatial distributions) can be displayed at the same time by loading multiple instances of the plugin.
data extraction

  • Extraction of values(planes, profile functions or single bins)

  • Question:
  • What’s the average dose
  • at a workplace?
  • Solution:
  • Rough estimate from the
  • 2D dose map (might not match in 3D!)
  • Foresee a geometric region in the input

  • Alternative solution:
  • Define arbitrary volume
  • interactively while browsing the data.
  • Calculate averages on-the-fly while
  • moving the volume through the data set
threshold detection
Threshold detection

Typical question:

Where is the region with values > X ?

MC simulation of

optical photon transport

No interactivity

& higher rendering times 

Better image quality 

Not yet sure wheter it will be in V3.1
