World: r3wp

is that for the golf game? :)

it could be - ive got to catch up with geomol re how he wants to 
do the drawing :)

updated the above links with alpine/mixed/lowland forest :)

eventually i'll fix the z-order and make the resources statix rather 
than dynamic

Very exciting demo, could you add some terrain scrolling to see how 
fast we can go with View ?

ill add scrolling in now - just finished support for non-square terrains

Not exactly terrain rendering ..... 
This screenshot is from a 3D surface drawing program.

Surface can be rotated in 3D .... http://farm2.static.flickr.com/1294/537895152_cf3312af08_o.png

same surface rotated slightly .... http://farm2.static.flickr.com/1321/537895150_a0e70d54bd_o.png

:)  What sort of performance are you getting Phil?

On my laptop .... I would gues about 5 frames a second ..... depending 
on how near the surface is to the camera.

hmm.. one thing that i would like to do when R3 comes out is to make 
a rebol 3D model viewer with rotation

although OpenGL plugin would simplify that a thousandfold

I did make a start on a 3D object viewer ... it would draw wireframes 
on 3D objects in the .obj format.

Most object do contain thousands of faces ... so you dont get great 
performance.

yes - but for 3d tools like wings3D you usually have less than 10000 
faces before you export to Maya/Lightwave etc

i normally use wings3D for the basic shapes then export to subdivide 
etc

is the rotation algorithm quite intensive?

I haveent optimisec it ..... for smallish numbers of faces you can 
get good performance .... (I'm no 3D expert)

It is processor intensive as it is written entirely in Rebol

Reb Rings Mini MGV released - see announce.  Mouse gestures etc.

yet another isometric type world renderer - http://rebol.mustard.co.nz/isometric-world.r

beautiful

very nice

Excellent.. This type of work could be the basis for a Rebol based 
GIS. Inspirational - thanks!

Or a nice & simple ORPG done with RS ;-)

Very, very cool James.

<--- is this layout possible?

Henrik, funny you should post that.............I'm in need of a way 
to take a 2D diagram, and turn into exactly that (which is called 
an isometric view).


A cool feature would be that the colour of a 2D rectangle, and perhaps 
even the line weight and colour would dictate the 3D height, colour, 
and treatment.


The reason I want this is that I'm building a diagram of the architecture 
of Qtask, and want to make it easy to see and understand.


What I'm planning to do right now is draw it in 2D first.  Then pick 
a good angle (in my mind).  Then build all the 3D objects on an isometric 
field (sort of like old video games like Zaxxon).


Then scale them into place.  Then add the text words in front of 
them.

I like the words on top vs side as well of the image you posted.

If you know what was used to generate that I would like to know.

reichart, I sent him an email with the question.

Thanks!

if you want to you can easily use the free version of houdini (http://www.sidefx.com/)

with your IQ that software should be pretty easy to grasp... if you 
follow one of the learning tutorials.

Actually, I have played with Houdini, will look again though for 
this application of it.

new draw based menu system released (demo). http://rebol.mustard.co.nz/onyx-demo.r
new Onyx grop created regarding it.

supports radio, check, standard and menu/submenu elements at the 
moment.

pretty zippy

yeah - itd be nice to see how it performs on slow computers :)

wondering what the 'dot' is that appears on the right side of the 
 divider over the menu item  "File > Recent Files"?

By the way, very nice looking menu.

the dot is me forgetting to put in an empty? check ;)

ICarii: Cool stuff

Henrik: I don't see any problem to render such isometric layout using 
DRAW.

coming soon! New onyx styles: field, label, area, check, h1 /h2 / 
h3.  Sample at - http://rebol.mustard.co.nz/new-onyx-styles.png

Draw a surface with 3-D Perspective and allow roation -

Is there a way to know the length in pixels of a text drawn with 
AGG?

I was just about to try  view layout [b: box effect [draw [text "test"]]] 
 planning to poke around with help b to see, then I remembered that 
REBOL Linux doesn't have draw text  :(  Sorry.  But that's were I 
would start....poking around in the objects.  May well be a waste 
of time... Then I'd fire up anamonitor and view through some of the 
system objects for that key ...size-text... kinda function.  If that 
didn't work I'd give up and wait for Cyphre :)   Excuse the babbling...

size-text will do it.

I doubt it. size-text expects a face argument and computes size based 
on face/text, face/font, face/edge and face/para values.

all of which you can change to expected agg fonts etc before calling 
size-text

s: size-text make face compose [text: (t) font/name: "arial" para/wrap?: 
off]  ;etc..

which is fine as long as you don't use vectorial ;)

as long as you use pen off/none with vectorial the results should 
still match :)
