can not get the correct point array from oddbspatialfilter
can not get the correct point array from oddbspatialfilter
my code as follow:
oddbblockreferenceptr insert =(oddbblockreferenceptr)pmsent;
oddbspatialfilterptr pfilt = oddbindexfiltermanager::getfilter(insert,
oddbspatialfilter::desc(), oddb::kforread);
if (pfilt.get())
{
odgepoint2darray points;
odgepoint2darray points1;
odgevector3d normal;
double elevation, frontclip, backclip;
bool enabled;
pfilt->boundary(points1);
pfilt->getdefinition(points, normal, elevation, frontclip, backclip, enabled);//the points.size is 32. elevation =0;normal =(0,0,1).but it seems that all of the points are not right.should i do some transform???fff"> frontclip = pfilt->frontclipdist();
backclip = pfilt->backclipdist();
odgepoint3d origin0 = pfilt->origin();
int ptsize = points.size();
}
spatial filter also contains a couple matrices. you can get them from odgiclipboundary using.
code:
odgiclipboundary boundary;
bool benabled;
pspfilter->getdefinition(boundary, benabled);transformation matrix for boundary points to block's space would be:
code:
odgematrix3d toblockspace = boundary.m_xinverseblockrefxform * boundary.m_xtoclipspace.inverse();note that m_xinverseblockrefxform is inverse matrix for block reference at the moment spatial filter was created.
