Detailed Description

Callback when the model view matrix of the main camera has been updated.

Note that the callback is only fired when the model view matrix has been changed, i.e., not each frame, another callback has to be used for that.

For polling use: if ( mvmFinder->isUpdated ) { agxOSG::PrimitiveSetTriangleSorter::sort( *geometry, mvmFinder->modelViewMatrix ); mvmFinder->isUpdated = false; }

The isUpdated flag is set to false if onUpdated callback is valid and has been called, if onUpdated = {} then isUpdated has to be set to false externally when the updated model view matrix has been seen.
