From F3 to JavaFX 1.0 - Effects

An important and impressive innovation between F3 and JavaFX is the Effects framework created by Chris Campbell.

F3 had a simple system of software pixel filters, which could be applied to any Node or group of Nodes in a scene. However, thanks to Chris, JavaFX 1.0 includes a much more complete set of effects, and a sophisticated framework that enables GPU hardware acceleration where available.

Underlying the simple declarative expression of effects at the JavaFX script level, effect implementations are described in a GPU-shader-like procedural language, which Chris created, called JSL. Chris's JSL compiler then compiles to various targets, either GPU-based (GLSL/HLSL), or CPU-based (Java/Native).

Comments:

Considering this post and your previous post, 'Media,' I was wondering how close JavaFX is to having (in your opinion) the right level of hardware acceleration.

To date, JavaFX has shown promise, but I haven't seen the responsiveness or silky-smooth framerates that I think can be achieved on the JVM platform (e.g., what Arial Malka has done at slashrun.org or chronotext.org with applets + jogl).

So I was wondering, how close are we with JavaFX 1.0? 50% there? More? Less?

Also... I remember seeing something in the bug reports about coming up with a better font rendering solution than the windows standard cleartype renderer... are there any efforts being made in that direction?

I want to believe! I think JavaFX is a step on the right path.

You can answer the question by measuring the JavaFX 1.0 frame rate and dividing by 60 - that will tell you how close we are.

For the silky-smooth animation we all know and love 60fps is required.

We shouldn't have to and can't settle for less.

whoa, JSL? I haven't even seen mention of this before. Where does one go for advanced tutorials based on it? so far I've only seen stuff like binding, and language tutorials.
