@altert Ah, that's great! We're planning on doing something similar, with IR and x-ray images of paintings. Our designer has a comparison slider in mind; we're not sure yet if this project will be using OSD, but if so, I'll give it a shot!
Really digging the light source position selector. Very smooth!
Well, I had just written the svg overlay at that time, so I think I wanted to put it through its paces. I also like the fact that the svg overlay outlines grow and shrink as you zoom, though of course the m2 demo doesn't really take advantage of that.
http://www.letsfathom.com makes much better use of svg overlays (hover over any album... that text and those icons are all done with the svg-overlay plug-in)
I would imagine svg overlays are better for performance, but I don't know for sure. Of course it doesn't really matter when you only have a dozen overlays or less
Just making stuff up here...What about an overlay based on an ellipse (or circle)... is there a substantial difference this would bring compared to the rect type overlay? Or an overlay which is positioned and which rotates around a given point. Or an overlay that can rotate independently of the viewport - can we already do that? How about an overlay comprised of a closed path?
