A study was performed on the opportunity of buying, for the ICTP use, one of the following visualization systems: Advanced Visualization Systems (AVS) - release 5.02 IRIS Explorer - release 2.2 from NAG IBM Data Explorer (DX) - release 2.1.5 Khoros - Developer`s Release 2.0+p2. Criteria for an optimal choice were defined and it was concluded that none of these visualization systems would be a good today compromise. Conservative consideration of the market opportunities shows that substantially improved releases of these systems are expected to be operational within at most an year. For short term period, the ratio benefit to burden still makes public domain low-end graphics attractive. (author).
