Even tho I don’t consider it as technical, the magnifying glass effect looks decent enough and even good as it features some handmade graphics. Being myself a humble pixel artist I always appreciate effects with a nice touch of design and even better when they include pixel artwork. As for the effect itself, it simply shows a round magnifying glass bouncing or moving on screen and showing zoomed parts of the background graphics.
Sure, I am not a coder yet I know this effect can be a « trick » as it only requires to have 2 versions of a picture in memory : first the real size one and secondly a zoomed version. Then it can be easy to simulate the magnifying glass effect. But like I said, I am not coder so I may be totally wrong here. Besides only the end result matters not the means used 🙂
I’m afraid we are not given so many examples of this effect as with the wormhole or city skyline. Yet we can live with this situation as it may be a nice looking effect but as others it tends to loop quite fast and isn’t so impressive either.
Well I think all that needed be said has been said. Not quite a technical effect, yet very pleasant thanks to the graphics used, the magnifying glass effect comes as a gorgeous demo filler. However it would need new ideas if we want to see it back under a new shape. Time to see it in action :
This magnifying glass effect that can be seen in the 2001 Odd Stuff demo by Sector One and Dune perfectly illustrates my writings : coloured graphics, nice colors and moving waves on the sides make it a nice looking screen.
This other example taken from the Second Reality 2013 demo by Checkpoint is a bit different : luckily the magnifying glass being blue is a lot easier to spot. Besides it is quite big and keeps bouncing from one side of the screen to the other. Ok maybe the « zooming » feature is not so stressed but let’s not be negative and enjoy the show instead ! 🙂
