As part of the [[Canvas]] project, we also talked about providing a standalone [[FGCanvas]] startup mode, analogous to how [[FGPanel]] works, however as part of the main FlightGear code base, rather than duplicating the existing source code. However, this turned out to be a little tricky due a number of hard coded assumptions: | As part of the [[Canvas]] project, we also talked about providing a standalone [[FGCanvas]] startup mode, analogous to how [[FGPanel]] works, however as part of the main FlightGear code base, rather than duplicating the existing source code.

Unfortunately, there are many hard coded assumptions in the code currently. The code OFTEN assumes that there's a an aircraft, FDM scenery, sound etc. Basically, all the stuff and subsystems that won't be needed by a standalone FGCanvas/FGPanel. And the next funny thing is that all the Nasal code in $FG_ROOT/Nasal is also making lots of these implicit design assumptions (such as geodinfo() calls (depending on scenery/tile mgr) etc). | Unfortunately, there are many hard coded assumptions in the code currently.

Basically, this means that there will be lots of refactoring involved for a standalone canvas client, not just C++ code, but also Nasal code. | Basically, this means that there will be lots of refactoring involved for a standalone canvas client, not just C++ code, but also Nasal code. | ||
