Nice tips . Horizontal Cross Panorama - is the panorama type you described .
The software named Bixorama can convert other panorama types into your VBE format .
1) QuickTime VR .MOV
2) DirectX .DDS
3) Latitiude Longitude
3) Latitiude Longitude
4) Horizontal Cross
5) Vertical Cross
6) Strip
7) Strip XYZ
8) Single Files
9) Sphere Map
10) Mirror Ball
11) Heart Shaped
So you can make your own panorama for different project in archicad or artlantis and save as MOV panorama and you can convert for VBE.
AS A TEST IN Artlantis i have rendered six separate renderings of a simple empty scene with ground plane ( with white-blue fog at horizon line )
To have not corners effect you have to distort with Bixorama -
Without distortion you can have visible corners effect.
After that i splited the six squared images with photoshop .
