how to get transformation matrix from entity?
hi,
i need to get transformation matrix of each entity..
is it possible to get??
thanks in advacnce..
this is what i use
i use this to get the matrix to travel from the world-space origin to that of the entity:
code:
odgeplane gep;
oddb::planarity plan;
ent->getplane(gep, plan);
odgematrix3d::worldtoplane(gep)i use this to get the matrix which travels from the entity space to the world-space origin:
code:
odgeplane gep;
oddb::planarity plan;
ent->getplane(gep, plan);
odgematrix3d::planetoworld(gep)here's hoping that is what you're looking for.
note that getplane() works only for planar entities.
also for some entities the plane's origin is set to some non-zero value.
some planar entities return coordinates in wcs.
where is no general solution "to get transformation for each entity".
