Well, I'm not sure which aspect of this to look into. The goal is to tie a glyph into the coordinate space of a transformed object (Rotated Sphere), with the stiff requirement thta the glyph not to be zoomed in when the object is zoomed. Is this possible ? Sounds like a screen object just plain won't work. Is it the characteristic of being a screen object which makes the glyph not zoomable ?
My sphere is rotated once and then fixed - it is not interactive. So could I (I'm grabbing at straws, obviously) somehow make a 2-d object from the 3-d object for display purposes, the idea being to get it and the screen object (glyph) into a coincident space ?
