trouble with odgsopenglvectorizedevice::update()
trouble with odgsopenglvectorizedevice::update()
hi,
my rendering code used to work fine with dwgdirect 2.2.0 but after updating to dwgdirect 2.3.1, i am having some trouble with rendering.
i am using seperate devices for primarydraw(using opengl) and overlaydraw(using gdi). trouble seems to appear in primarydraw device.
whenever i have more than one entity in drawing (eg. 2 lines) and i modify entity's z-coordinate, the primarydraw device gets stuck in update() (some infinite loop eating all memory.)
-if there is only one entity in drawing (eg. 1 line), the primarydraw device seems to be working fine.
-if i invalidate odgsmodel after modifying entity's z-coordinate but before issuing refresh, the primarydraw device seems to be working fine. (odgsopenglvectorizedevice::gsmodel()::invalidate( odgsmodel::kinvalidateall))
i tried to reproduce this problem with odamfcapp but it handles the situation without any trouble.
what should i be keeping track to avoid this crash? has any rendering code changed since dwgdirect 2.2.0 ?
thanks.
