dwgdirect vs viewkit
dwgdirect vs viewkit
i just want to quickly view, zoom and pan an autocad drawing.
in viewkit, i was using addrawdrawing in onpaint()
in dwgdirect, i use odgsdevice::update() like in odamfcapp
but it is very slow to redraw when i make a zoom or a pan !
is there something to change, like ad3parm.accuracy in viewkit, to make it faster ?

rendering functionality is not ready yet and current implementation does not use any type of cashing and optimization at redraws. this is to be improved.
btw, file loading and rendering time differs greatly in debug and release versions.
