how close will be the dwgdirect rendering to autocad renderi
how close will be the dwgdirect rendering to autocad rendering machine?
hi all,
can someone from the opendwg guys say a few words about the new rendering functionality?
for example in the autocad model we cannot draw entities which will stay the same size regardless of the zoom (since we have a gi geometry class). this is actually not an important limitation but will we have more access to the rendering machine in comparison to autocad one?
thanks for any reply.

in autocad entities are able to draw themselves viewport-dependently (viewportdraw() method has access to viewport data). example: point entity can be drawn having size depending on viewport height (pdsize < 0).
in dwgdirect it would be possible to draw something viewport-dependently too (icon for example).

thanks for the info.
and another question (sorry for such disturb):
can the rendering classes be used for some user interaction: for example highlighting an entity, hiding entity (without regen of the whole model), fading entities (as in the edit block reference command), dragging or rotating in 3d?
of course not everything in the first rendering release but for the near future probably?
thanks.
