operation order
operation order
hi!
i have one doubts with the order of some operations. i have a text and i call this function:
oddbtextptr text;
text->setposition(odpoint3d(x, y, z));
text->setnormal(odvector3d(nx, ny, nz));
is the same what:
text->setnormal(odvector3d(nx, ny, nz));
text->setposition(odpoint3d(x, y, z));
thank you!
the order of operations is important. setposition() accepts world coodinated (wcs). but position is stored in text entity in object coordinate system (ocs). ocs is defined by normal.
so you should set normal first.
