Most of the IG industry uses CIGI to pass data from the host to the IG (and back for end of frame and mission functions stuff). I'm sure the architecture is well defined on this.
For starters, you can take a look at Boeing's Multi Purpose Viewer software which is an IG test bed for the CIGI protocol. They interface it to a generic host. The Multi Purpose Viewer uses OSG on the backend for rendering. This might give you some ideas on what you can do to add CIGI into your IG stuff... -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Torben Dannhauer Sent: Tuesday, March 29, 2011 6:45 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Camera control in osgvisual Hi Vijeesh, here is some explanation how the SLOT mechanism works currently: it is a list of SLOT classes. A slot class contains the following members: * string name * double value * string sValue (string value) * enum direction: TO_OBJ | FROM_OBJ * enum type: STRING | DOUBLE If a software module wants to store some values which are directed TO the visual Objects ( e.g. object3_LAT), it searches in this list for the slot with the corresponding name, type and direction and stores the value in it. The object updater for example reads on every update in this slot list for a slot with the appropriate name and read the value to apply it to its own object. This has the the following implications: * Supposed to be very slow if lot's of variables are used: if someone searches in the list, he has to perform many string comparisons. * Only strings and doubles can be stored but no complex data structures ( e.g. cigi containers) My approach with the "slots" was only a "first shot". I would be very glad if we could discuss this, maybe also with other users in the forum. It would be great to construct a more sophisticated and usefull architecture to manage the data of the IG. After that I would implement this solution asap, but currently I have no idea in which direction we should proceed. Thank you!
