3d coordinate transformation ???? (no ideas ???)
3d coordinate transformation ???? (no ideas ???)
hi all again,
i'm very sorry if i insist, but i'can't solve my problem, and i'm a little bit frustrated... .
i'll try to make my question in a different way:
is it possible in dwgdirect (i'm sure it is, but can't find how...) to transform the dwg entities original (world) coordinates using some transformation rule ??
in the documentation there is a section explaining the coordinate transformation matrices, but i didn't find any example explaining how to modify the "standard" behaviour...
sorry for my insistence, but this is a very big problem for me and i lost the past two days trying to solve it!
thanks, carlo.

dear carlo,
dwg format contains objects, that stores data about world->eye transform, that is used in the file. these are oddbviewporttablerecord for model space and oddbviewport entities for pape space.
dwgdirect rendering takes into account properties of camera, that are stored in these objects
sincerely yours,
george udov
