Change the osg::NodeVisitor::getLocalToWorldMatrix() /
getWorldToLocalMatrix() methods so it do not initilize the matrix being
passed to them, and assume the the users has already initiliazed them
appropriately, such as to take account of camera positions.
coords of the intersection point with the scene rather than the world
coord value for that point. The code now uses
osgUtil::Hit::getWorldIntersectionPoint() method for getting the world coords.
Added support for getWorldIntersectionPoint to Viewer.cpp.
Put and #ifdef around the setting of the default display list visitor so
it nolonger sets in under IRIX. This is a world around to the IR graphics
imbending lighting info into display lists, if the display lists are
created before state is set up it produces lighting artifacts such as
flickering. Remove the the default display list init visitor removes
these problems, display lists are then built on the fly and drawables
a drawn for the first time.
does not flatten drawables which have double references to them, but only
one reference with a static transform on it. This case can't be flattened
but this wasn't picked up. The code now detects the case correctly.
distribution clean from GUI examples, these instead should live in the bazaar.
This can better accomodate the many different types of viewer that users are
developming.
the conclusion that the osg::Matrix::inverse was broken, have lifted a new
implementation from sgl and it seems to work fine. Will need further testing
but looks good.
objects that are deleted whilest still having a positive _refCount, such
as when a object has been deleted on the stack, yet other references still
exist for it. Have put the desctructor implementation in Object.cpp to
avoid adding yet another file with only a couple of lines of code in.
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required. Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.
Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.
