3D Graphics Window

If you encounter any problems in displaying MRI slices in the 3D window in Source Analysis, then it is possible that a graphics card setting needs to be changed. This is done in the besa.ini file.

To change the setting:

1. Close the BESA Research program.

2. In File Explorer, locate the besa.ini file. For the example of a BESA Research 6.1 installation, in Windows 7, Windows 8.x, and Windows 10, it should usually be located under C:\Users\Public\Documents\BESA\Research_6_1\

3. Open the file with a text editor. Towards the end of the file, you should find the following section: 

[Mapping]
UseBitmapDrawing=On
Use3DVBlending=On

4. Change the entry Use3DVBlending.

You can try three different settings. Choose one of:

  • Use3DVBlending=On
  • Use3DVBlending=Off
  • Use3DVBlending=Auto

One of these should work for your graphics card.

The example below shows a 3D MRI slicing with blending set to "Off" and to "On".
