Hi Hongquan, Based on your description, I think foci files may be the best fit for your needs. Tim is correct that foci have to date been more extensively used in Caret than in Workbench and that there aren’t yet a lot of wb_command tools for manipulating foci (but there are a few listed in wb_command -list-commands).
Foci can be generated in wb_view using options available in Toolbar: Mode: Foci, and their display can be controlled in Features Toolbox: Foci Foci can be viewed in relation to volume slices as well as surfaces. Also, if you decide to start by working with foci using the (currently) greater capabilities in Caret software, they can be imported for wb_view visualization using wb_import If you have specific questions as you proceed, please post them to hcp-users. Likewise we welcome specific feature requests, as Workbench is under ongoing development. (Indeed, we plan a new release this winter, with some very handy ‘annotation’ capabilities for adding text and symbols and saving them in scene files.)
