bubbles
 

Were the bubbles made the same way as the fish, with two
images then the computer fills in the rest?

SUB

The fish are 1 image and the 3D model is morphed between 2 keyframes.

The bubbles are a moving texture wrapped around a slightly twisting object as well as bubble sprites overlaid.

There are 3 layers of bubbles - A moving image of small bubbles moving slowly in the background, then another layer moving upward slighly faster, and finally random larger individual bubbles that move from side to side as they travel upward.

I was wondering how they are moving. Is it
a traditional animation? That is what i am
curious about. ( my question
might be foolish, I am still trying to
understand the difference between
vertex animation and tradional animation
and if traditional animation an be mixed with
vertex animation.

The two layers of background bubbles are simply tall pictures which are dragged upward and repeated at the bottom when they go off the top of the screen. The individual bubbles are small square polygons with a picture of a bubble in each, which are moved upward and side-to-side by changing their coordinates frame to frame.

So, that 's how the fish are able to swim throught the bubbles!:)
