World: r3wp

is RebGUI widely used ?

I used it for one program that was used to fix translation of Windows 
Vista in 15 or 19 different languages. It depends on your definition 
of "widely".

Rebolek: I meant "was it a good alternative to VID ?". The only thing 
I miss in every Rebol GUI I've seen is font antialiasing.

kib, if you run under Windows and wants anti-aliasing:

view layout [box black effect [draw [text "Hello World!"]]]

font-A: make face/font [size: 32]

view layout [box 200x100 black effect [draw [font font-A text "Hello 
World!"]]]

view layout [box 200x100 black effect [draw [pen red fill-pen yellow 
font font-A text "Hello W
orld!" vectorial]]]

Geomol: in this case, you're drawing them with AGG. Your text is 
not selectable.

But that gives me an idea : is there something like NodeBox in Rebol 
?

right, you figure that part out and make a nice GUI for us! :-)

No problem! give me just a min ... or a year :)

NodeBox? Something like splash?

do http://www.rebol.com/view/demos/splash.r

No, NodeBox is for poets : http://nodebox.net/code/index.php/Gallery
. Have a look at the Helsinki gallery : it's really beautiful.

Brendan Dawes' work is also interesting.

ok, looks nice!

I don't know, if anyone has done something similar in REBOL. There 
are demos flying around. I made a very simple Bezier demo once:

do http://www.fys.ku.dk/~niclasen/rebol/fysik/bezier.r

It could be a start to make something better and more beautiful.

It's like Processing ( http://processing.org/), I like this page 
made with it : http://www.wblut.com/2009/01/27/strange-symmetry-2-lite/

and REBOL got the speed, I think, if you try Cyphres demo:

do http://www.rebol.com/view/demos/cyphre.r

Fun! And you can had more control points I suppose ?

yes, shouldn't be too hard.

Whao, cypher is really quick and beautiful.

cypher --> cyphre

yup

LOL just found this:

do http://www.rebol.com/view/demos/imagination.r

move your mouse around.

Yes, wonderful job. Who did these demos ? Amiga fans ?!

hehe, they may be from a contest a few years ago. You can find them 
on the ViewTop under REBOL.com/Demos/
RZoom is also nice (by Henrik).

I'm amazed by cyphre source file : just a few lines.

I've made a C DLL on linux which has the rudiments of an image processing 
function. At the moment it just sets one pixel.

I've made C DLL on windows previously, so I will try to make it cross-platform.

Anton: interesting...do you have any screenshot ?

Boring... my test image is 2x2.

:)

What platform are you on ?

Windows (Seven)

Ugh...

I never had a problem with it since a month. It's really stable.

Ok, whatever. :-P

(-; I don't mean to be rude by that..)

No problem

Anton, have you seen new speedy version of my tunnel script ? :)

Lookup table for pixels position and tunnel coordinates helped a 
lot...

I guess your dll would help. Would you keep acceleration only for 
pixel drawing? or maybe some higher functions?

Oh no! Calling a DLL function just to draw one pixel would be so 
slow! I will of course make it process a whole frame at a time. So 
basically, I think the tunnel drawing function will move into C.

Just tried latest version - framerate at least double.

Ok, so you've pre-calculated the pixel mapping, avoiding the square-root 
and arc-tangent etc. in the main loop.

You lost some possible dynamism by making this move. The C should 
be fast enough to calculate it on demand.

Anton - how's that your following demo is decently fast? Is it completly 
different technique?


do http://www.rebol.net/demos/7B191CB087929081/christmas-drive2.0.1.r

heh, fun! Makes me think of Out Run: http://en.wikipedia.org/wiki/Out_Run

Yes, in that one I used AGG to scale and composite a relatively low 
number of frames, zoomed to different distances.

looks nicely smooth, and fast. Almost screams for addition of small 
car and doing some simple game upon it :-)

Yes, I was thinking of the techniques used in games like Out Run 
while I making it.

Reminds me also of Lotus Turbo Esprit (Amiga)

Pekr, on my old machine, I was hitting the limits of detail I could 
put in without reducing the framerate too much. I had to tweak it 
a lot to keep it looking fast and detailed enough. It was difficult.
