shell vs polyline function in odreadex
shell vs polyline function in odreadex
hi,
i recently started to learn dwgdirect and have a qustion about the sample programs.
in odreadex sample project, i would like to get odgigeometry::shell called for acdb3dsolid in order to get face sets. but the function that gets called is only polyline.
in odvectorizeex sample project, i could get shellproc function called by changing rendermode of odgsbasevectorizeview or changing the shade type on dwg files using autocad.
what change do i need to make to get odgigeometry::shell in odreadex? or do i totally misunderstand the comcept of odgigeometry functions?
i would appreciate any help. thank you.
3dsolid can be rendered as wireframe, shell or both of them depending on regen type. odvectorizeex uses render mode from viewport being vectorized.
readex dumps each entity individually without any viewport context.
which function (or both) are called depends on value returned from odgiworlddrawdumper::regentype().
btw, probably you modified the sample - i get shellproc called in readex for 3dsolid.

thank you, sergey,
let me try that.
i tried changing the return value from odgiworlddrawdumper::regentype() in readex sample. i tried all the regentypes. odgiworldgeometrydumper::shell() function never got called. only odgiworldgeometrydumperlyline() got called with 2 verteces for each call.
i used the attached file. it's 3dsolid. i want face set not just edges from the object.
i modified odreadex sample. i modified dbdumper::dumpentity function so that 3dsolid enities call its worlddraw(). and odgiworlddrawdumper::regentype() returns kodgistandarddisplay. what else do i need to change to get odgiworldgeometrydumper::shell() function called for 3dsolids?
attached files (25.5 kb, 6 views)

the problem was solved by changing the return value of regentype to kodgirendercommand.
and i also forgot to add
odrx_declare_static_module_entry_point(modelermodu le);
odrx_begin_static_module_map()
odrx_define_static_application("modelergeometry", modelermodule)
odrx_end_static_module_map()
it was written in
3d wireframe data
can dwgdirect read 3d wireframe data from dwg/dxf? if so, where can i find out the corresponding document?
thanks,
yli.
if you mean wireframe data of 3dsolid objects:
it can be stored in dwg file (but may be absent). and it is not stored in dxf.
dd can generate the wireframe from acis data stored in 3dsolids. it's also able to generate shells.
odvectorizeex sample shows how the geometry of entities can be extracted.
