World: r3wp

translation for clip would be nice.  I was making a custom card game 
where clipping was being used repetitively and constantly resetting 
the clip coords as well as translating the draw commands was rather 
clunky :)

the coolness that is AGG/Draw realtime terrain rendering :)   http://rebol.mustard.co.nz/terrain.jpg

bring on R3 and even more speed! :)

Is that what your mahjong tiles look like close up?? ;)

heh - ive been toying with converting some old vb6 terrain stuff 
i did into rebol for a while

map readers etc

wow, did you do that?

(terrain rendering?)

yeah - a while back i used to toy a lot with terrain rendering.  
Back in 2001 I downloaded a large set of NASA data (1GB+ maps) and 
was using them for different rendering tasks.  Back then I had to 
use VB6 and C++ as REBOL didnt have a binary skip :)

This latest rendering was just a test to see what the triangle speed 
limits were using a height map and a colour map.

The alpha is just a nice bonus :)

hehe

anyhow, its pretty ... is it any fast?

its realtime on this pc but this is an AMD64 with 2gb ram etc..

ideally id like to implement real 3D rotations rather than isometrics 
:(

guess ill wait for R3 and the vector type

ICarii: very nice terrain rendering !

Yes, really nice!

Very nice indeed.

real time !!! wow.

ah... just read... not 3d rotations... I guess that is part of the 
reason for speed.

pretty nonetheless  :-)

more playing with AGG/Draw - Comic Terrain - http://rebol.mustard.co.nz/comic-terrain.png
 or for the script - http://rebol.mustard.co.nz/comic-terrain.r
  Admittedly I am not an artist ;-)

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.
