3d coordinate transformation ???? (updated)
3d coordinate transformation ???? (updated)
hi all again...
ok, digging into the opendwg documentation i found that there is the possibility to obtain the transformation matrices from the odgsview class. these transformation matrices are just what i need to modify, but... how can i implment my projection matrix, for example ?
do i have to derive my own class from odgsview ??
if so, how can be done ?? (i tried but the vc6 compilre gives me tons of errors saying that there are a lot of odgsview pure virtual functions not implemented in my class... i don't need them, just need to override the projectionmatrix function )
is there an example of this ?
i can't find anything like this into the examples provided with dwgdirect 1.14.01.
do i miss something ???
thanks again to everyone!
carlo.
