What's new in S-GeMS 2.5 Beta
Dec 28, 2011
- Improvements:
- Regions:
- All geostatical algorihtms can be constrained within a sub-space of a grid. This sub-space is defined by a region. The region is well implemented within the algorithms but had not been implemented for the visualization. This feature will be available in the next version (likely January 2012).
- Python commands:
- Several python commands had been added to provide better control from python scripts. See here for a list.
- CSV file format:
- SGeMS can now load data from comma separated file (csv). The first line containes the names of the variable with the variables in following lines.
- Alpha numeric field:
- SGeMS can now load alpha numeric field when imported from a csv file format. There is now a structure called a categorical definition that will provide the mapping between a alpha-numeric field and its corresponding numerical values.
- Groups:
- Property can be grouped together for a cleaner display. For instance a set of simulations ort indicators will be inside one group. Python commands had been added to use that functionality.
- Right clicking actions:
- Right clicking on a grid, a group or a property name provides some options such as creating indicator data or taking the log of each value within a property.
- Pyhton plugins:
- You can have access to user-defined python script when right-clicking on either a property or a group of properties.
- Quadrant Search:
- Specification of search strategy for the variogram-based algorithms.
- Masked Grid:
- A type of grid that is build by applying a mask on a cartesian grid. The advantage is that if only 50% of the blocks are actually active, the array necessary to store the values will be 50% smaller than the one use for the full grid. This is mostly useful on very large grid. A masked grid could be mimicked by using a cartesian grid with a region defining the mask.
- 64 bits
- Eanble the use of very large grids and better performace of the SNESIM algorihtm.
- Regressions:
- Volume rendering:
- The volume rendering is now only possible on NVIDIA video card. This will not be fixed on this version since the next SGeMS release will have a completely new (and improved) visualization features that includes the visualization of the regions.
- Variogram modeling:
- The regions had not been implemented in the variogram modeling tool. This part of the software is unchanged hence has fallen behind in this version.
- Kriging from blocks
- The algorithms BKRIG, BESIM and BSSIM have been removed, they were too unstable and I do not have the time to maintain them. Contact me if you were interested in these algorithms.
