示例1: startGrab
void LLToolGrab::startGrab()
{
// Compute grab_offset in the OBJECT's root's coordinate frame
// (sometimes root == object)
LLViewerObject* objectp = mGrabPick.getObject();
if (!objectp)
{
return;
}
LLViewerObject *root = (LLViewerObject *)objectp->getRoot();
// drag from center
LLVector3d grab_start_global = root->getPositionGlobal();
// Where the grab starts, relative to the center of the root object of the set.
// JC - This code looks wonky, but I believe it does the right thing.
// Otherwise, when you grab a linked object set, it "pops" on the start
// of the drag.

LLVector3 grab_offset;
grab_offset.setVec(grab_offsetd);
