RE: Re: Interesting read about scriptless animation

Hi Joe,

 

Your examples didn't seem to make it through, so they may be needed for me
to see what you mean.

 

Usually when I want something to blink I do something like

<animate attributeName="opacity" values="0;1;0" ./> or use a collection of
sets as in the bottom illustration at 

http://cs.sru.edu/~ddailey/svg/2011/SMIL.html 

 

It seems like rotate is more naturally cyclic than translate, so I don't
think I'm following the distinction (probably since I can't see the
examples).

 

I find it quite intriguing to solve problems with these approaches (whether
or not "declarative" in the proper sense of "declarative programming")

 

Cheers

David

Hi David,

I have noticed that when I code in SMIL that I have to break the tags 
into 2 categories, depending on whether they will cycle. By that I mean, 
rotate, skew, translate, and scale will cycle, but all other SMIL tags 
will only cycle if they reference a tag that cycles. For example, if you 
try to use a set attribute on opacity to blink a light, the light will 
not blink unless you reference it to a tag that will cycle such as scale 
( won't cycle). Is this by intent? If it is, then I wouldn't say 
that SMIL passes as a declarative language. You could call the animation 
tags declarative, or maybe you could call the other tags a declarative 
markup.

For example, this will not blink.







But, this will blink.
































Best Regards,
Joe
