Water reflection

I was messing about and experimenting and I came up with an example of how to make realtime reflective water. It would probably make a good screensaver with a little editing.

Anything in the top half of the frame is reflected in the water below and distorted by animated waves. To see the realtime reflection, pressing the left mouse button will set off a firework in the sky, and also the glowing green pointer itself will be reflected.

It uses the Viewport object for the reflection, the Lens object for the distortion, and also the Perspective object which isn't important but adds a nicer effect of depth.

Shiny.

Yes, yes it is, thanks.

Nice use of my extensions ;)
Thanks for sharing, it looks really cool and could be a great "reward" for a player when they finished a game or something :)

They're really useful and pretty extensions too, thanks. If only there was a hardware runtime for MMF2 then the framerate for such things would be improved.

Yeah, although I think Andos would then need to rewrite his extensions to use hardware.

Now all we need is HDR support for MMF in order to overbrighten the reflection of the glowing green ball thingy :P

Yeah, or maybe a Vaseline Lens extension.

Nice but slow. It runs at 15FPS :(

I got help from Yves and I'm currently working on improving the speed dramatically (i hope) for the lens object.
Its really difficult to make it use hardware acceleration. It would be easier if MMF2 had a hardware accelerated runtime to handle the stuff in a unified system.

Wow. :)

All the Transform Extensions are used..:D

But that looks awesome, really.

@Andos
Just a siggestion for the lens object, Many vectorbased programs such as Corel Draw and Xara X has filling methods based on math instead of actual bitmaps, this is way faster. Could such an option be implemented? When a water effect is created I just end us using a small tiling graphic anyways....

How would this lens effect look like in math? ;)

Oh btw, the Viewport extension might not even be needed in your example. The Lens object has a feature to change it's source regions (offsets from it's position) and you can set a negative vertical multiplier to get a reflection.

You could also simply draw a gradient over your wanter lens image to give it the perspective effect instead of using the perspective object, but that will only work if you scroll the lens image horizontally instead of vertically. That way you could save the CPU by removing the other objects.

That's why i said an option... If you look at the lens image in the example you can see what I mean!

Nice work. I like it. Thanks

Looks neat, well done!
