acdbabstractviewtablerecord::centerpoint() ?
acdbabstractviewtablerecord::centerpoint() ?
hi,
i need to render an autocad drawing in the same view that was saved in the drawing itself.
i was using overrided odgsbaseview::setview(
const odgepoint3d& pos,
const odgepoint3d& target,
const odgevector3d& upvec,
double fieldwidth,
double fieldheight,
projection projection);
but it seems to me that it is not the full information needed at all - when there is a middle mouse button pan in acad, then only the viewcenter point is changed (viewctr var) and not the camera parameters passed here.
that's why i'm accessing the acdbviewporttablerecord (when in model space), to achieve the centerpoint stored in the drawing.
but what should do with this view center point to make it work at least for parallel view?
in our output system (based on opengl) i can set position and orientation of the camera, as well as view height. there is no view center and panning means changing the camera position.
i should change the position due to the centerpoint() or "pos" argument passed - how to choose which?
another: activate the 3d orbit command and make a pan only. now its view center that is not changed at all. camera position however looks updated.
thanks in advance for any help for getting out of this total smash...
regards
