About the native GUI option (using only what the OS provides), I'm 
pretty confident that the minimum common should be enough to cover 
most needs for business apps, I will do a prototype for the Red IDE. 
Having a free drawing x-platform canvas, for games and non-native 
GUI would also be needed, SDL seems to be the best backend for that 
AFAIK (that gives us also OpenGL for free).
DocKimbel:

Right, adding basic float support to Red is not difficult, but as 
floats are not needed internally to build Red, they are low priority 
(but if someone wants to contribute it, it will be welcome). Moreover, 
the runtime lexer is disposable code, it will be soon replaced by 
a new one with Unicode support and more complete syntax support. 
So extending it now for additional literal forms is a bit of waste 
of time.


If someone is interested in implementing float support anyway, the 
decimal! name is reserved for a future BCD datatype, so possible 
names are: real! or float!. It will be a 64-bit float, so mapped 
underneath to Red/System float! type. A support for float32! at Red 
level is not planned, converting float! to float32! at Red/System 
level when needed (i.e. OpenGL API) should be enough.

I finally got my OpenGL binding for Red/System in a form suitable 
for publishing:

http://red.esperconsultancy.nl/Red-OpenGL/dir?ci=tip


Currently, the only available backend is for PicoGL, which does software 
rendering with the TinyGL library and shows it through SDL.
Kaj:
20-May-2013
I made an SDL backend for my Red/System OpenGL binding:

http://red.esperconsultancy.nl/Red-OpenGL/dir?ci=tip


SDL with OpenGL is available on most platforms, and depending on 
your system, it supports hardware acceleration. So you can now choose 
between software rendering with the TinyGL engine through PicoGL, 
and hardware acceleration or software rendering with the Mesa3D engine 
through SDL. The two example programs can be compiled with either 
backend.
Kaj:
21-May-2013
I made an OS-Mesa backend on SDL for my Red/System OpenGL binding:

http://red.esperconsultancy.nl/Red-OpenGL/dir?ci=tip


This does off-screen rendering in a memory buffer using the Mesa3D 
engine and then displays the result using SDL. Somehow I can't get 
it to work on Linux, but it's the first time I can use Red/System 
for OpenGL on Syllable. It circumvents two problems: the PicoGL library 
expects application functions that Red doesn't export, and Syllable's 
SDL port doesn't support the official OpenGL backend, so those routes 
both don't work. For most other targets than Syllable, the official 
SDL backend can be used.


It's also the first time that I have used my Mesa3D port to Syllable. 
I couldn't display the output before, because there is no display 
driver for the current Mesa3D versions for Syllable, just the standard 
off-screen rendering. It works great, even though it does only software 
rendering. PicoGL is a bit faster, but Mesa3D is a much more modern 
and complete OpenGL implementation.

I've added binary downloads for all Red platforms to the test repository 
of the two OpenGL examples for the Red/System binding: GL-spin and 
GL-textures.

http://red.esperconsultancy.nl/Red-test/dir?ci=tip


Test reports welcome. All platforms should work in theory, but so 
far I have tested Syllable and Linux x86. You need to have SDL and 
OpenGL installed (in 32 bit versions). SDL is included in the repository 
for Windows, and OpenGL should be included in Windows.

Kaj, great work on OpenGL!  Question: Am I understanding correctly 
that the OpenGL backends currently available don't use the hardware 
rendering in the GPU?  If this is a correct understanding, do you 
have a roadmap for including hardware rendering capability?  Just 
curious.

Kja, nice progress on OpenGL support!
Kaj:
21-May-2013
There's also the other way around: most GUI toolkits such as GTK 
have an OpenGL widget, so with my multi-backend design I can make 
OpenGL backends for the widgets of those toolkits. You'd have your 
regular widgets and then the option to use part of the window for 
3D

Kaj, I ran into Carl today in Home Depot and we talked about your 
SDL binding for Red.  Do you think it would be difficult to make 
a binding for R3?  Carl was saying that he thought it wouldn't be 
too hard to convert R3-GUI to run off of OpenGL instead of the current 
foundation (was it AGG?) so it could be hardware accelerated.

Just curious.

I don't think you would gain anything by using SDL to get R3GUI faster. 
AFAIK SDL has no 2d graphics support...it's just low-level lib for 
handling the OpenGL or 2d framebuffer. There is no support for 2d 
vector graphics, font rendering etc. so you'll end with the same 
needs for the UI engine in the end.

As Pekr mentioned above, with the new R3 graphics code reorganization 
I'm working on it will be possible to even create a compositor based 
on SDL though if anyone is interested in doing that.

Would it make sense to for a start, have a non-native GUI running 
on top of OpenGL? This is what you see from a bunch of different 
groups out there - e.g. using Lua (Corona, Gideros, Muai), Python 
(Kivy), Haxe, etc. This could maybe be done more quickly since I 
think there's already been some experimenting with OpenGL by Maxim, 
and others (Cyphre?). I guess taking this route would depend on how 
much work it would be to make Draw run over OpenGL, but it would 
open the door to a certain class of apps (games, graphics)..
Cyphre:
18-Dec-2012
AdrianS: re OpenGL. I see multiple ways here:

-try to HW accelerate the AGG graphics engine (currently used in 
R3) : I did some experiments which looks interesting. But the more 
you 'accelerate it' the more compatibility problems you get on different 
HW so it's about wighting the pros/cons.

-build completely OpenGL based engine (big task, brings lot of crossplatform/HW 
issues)


Otherwise it would be great if the current R3 graphics codebase is 
reviewed and some parts made more modular so different graphics engines/libraries 
are easier to plug-in. That should be not so hard work to do.

Cyphre wrote 2-Apr 2013 22:03:
For those interested in the 
alpha-channel change": ..."


It's a good change to get the alpha-channel 'right' or similar to 
most other standards. Have there been thoughts about including the 
alpha-channel with the RGB values, so it becomes RGBA, which we know 
from OpenGL and other places?

From my R3 console:

>> i: make image! [1x1 #{01020304}]
== make image! [1x1 #{
010203
}]


The alpha values seems to be left out. (It might have changed in 
newer versions.) Setting the pixel will include alpha values:

>> i/1: 1.2.3.4
== 1.2.3.4
>> i
== make image! [1x1 #{
010203
} #{
04
}]


But it seems, the alpha channel is separate from RGB values. Why 
not always have the alpha channel, and include it with the RGB values, 
so we have: [1x1 #{01020304}]
Geomol:
22-Jul-2013
And related: have there been thoughts about setting origin of images 
in the lower left corner instead of upper left? When I use REBOL 
to draw graphs (of scientic values), I always find myself flipping 
the y-axis. Putting origin in lower left should make such code easier. 
Textures in OpenGL has origin in lower left.

With HRD comes higher performant GPUs but I'm not sure how CPU scales. 
Look at Adobe, they are almost dropping support for classic display 
list (rendered on CPU) and forcing everybody to use their Stage3D 
which uses GPU. It's not easy move as there is almost no tooling 
yet, but it's a must. CPU is not able to process so many pixels with 
the new screens (with high frame rate). I don't say we should drop 
AGG support, just that there must come GPU support using OpenGL/DirectX 
and let the AGG to do high quality rendering of assets.
Bo:
21-Dec-2012
Actually, Oldes, that's a great idea!  R3's new GUI could be built 
to utilize OpenGL by default.  That way, the GPU would handle all 
the graphics calls, and R3 would have 3D capabilities built-in as 
a bonus!  This would probably even make porting to Android and other 
platforms a lot easier.  In fact, doesn't IOS (iPhone) use OpenGL?
Oldes:
21-Dec-2012
It is. OpenGL ES2.0. As well as Android. Actually I don't think there 
is a chance to do GUI on these platforms without OpenGL.
Robert:

We did a short test some time ago to use OpenGL, works but is quite 
some work to implement it completely.
Cyphre:
21-Dec-2012
The problem of OpenGL is it is great for rendering bitmaps etc. that 
can be used in 'crossplatform' way and I'd like to make such frontend 
for R3.... But if you want to implement something like DRAW  in OpenGLyou 
are getting into troubles. To do it properly you would need to use 
GL shader fragments.
Cyphre:
21-Dec-2012
Ofcourse if you want to create classical 3d game from textured polygons, 
shaders etc. that's the area where OpenGL excells (and the developement 
was mainly focused)
Bo:
21-Dec-2012
Couldn't DRAW work the same way as it does now, but render to a bitmap? 
 Then that bitmap could be rendered by OpenGL like it does any other 
bitmaps.
Bo:
21-Dec-2012
Just think, though, if OpenGL was the default renderer for graphics 
in R3, you could create a flat surface for a 2D screen, but during 
the same session, you could create another flat surface for another 
2D screen at a 90% Z-axis orientation to the first, and then rotate 
from the first 2D screen to the next 2D screen in a fluid 3D way.
Bo:
21-Dec-2012
I did quite a few tests with OpenGL on R2, but the killer for me 
was the inherent delay with R2 calling the methods (functions) in 
the OpenGL dll.  I was still able to rotate an object created with 
over 1000 coordinate points 30 times per second on a quad-core computer, 
but that's probably 1000 times slower than you could do it with straight 
C on the same computer.
Oldes:
21-Dec-2012
I don't say you should use OpenGL for DRAW. There is no drawing api 
in Stage3D as well. I was proposing to use AGG to draw to bitmap 
with the best possible quality and let the HW do what it's made for.. 
to move pixels around. Bo understands it. That's actually how are 
modern apps made to have 60fps. To make animations just in AGG will 
not work (and honestly never worked). But maybe I'm too involved 
in animations and for many people would be enough to have static 
content. But that is not for future.
Cyphre:
21-Dec-2012
Oldes, I don't argue with you and Bo about that. I think we all know 
the state of this technology. I've already did several prototypes 
of such "engine" so I have some ideas how this could be done for 
R3 it's just matter of prioritizing&time&resources.

I wrote about the drawing apis just so other people know OpenGL is 
not any Messiah if you want to do hi-quality 2d vector graphics in 
realtime.

I'm not against HW acceleration at all. It's just not easy topic 
in this non-ideal programming world as you pointed out.

I see the solution with good high quality rasterizer + HW accelerated 
compositing engine. That should be flexible setup at least IMHO. 
Plus this way also we got the classic 3d api for free.
Cyphre:
21-Dec-2012
Bo, I even tried to HW accelerate the AGG renderer code so it is 
completely using OpenGL...works well and you can use draw directly 
inside the OpenGL context mixed with 2d surfaces or 3d objects...lot 
of fun. But still , lot of stuff is still computed on CPU that way. 
Nevertheless its still better that fully SW based renderer.
Cyphre:
21-Dec-2012
Bo, I think if we don't make drastic changes to the GOB mechanism 
we should be safe when building anything on top of the GOB datatype. 
The gob! is in fact abstraction layer between the "VIew engine" and 
any "GUI framework" written in REBOL.
So as take this example:

We have now R3GUI framework which runs quite well on the current 
View engine (although this engine was build in 2 weeks during the 
very early R3 alpha work so it's kind of Q&D prototype ;))
(BTW should I mention the R3GUI is much better than R2 VID?)

Anyway, the R3GUI works on current View engine. When I tried to change 
the engine so it uses OpenGL accelerated AGG the R3GUI still worked 
without any problem (except visual bugs caused by incomplete OpenGL 
code implementation of the new prototype).

SO from that example you can see the "View engine" and "GUI framework" 
are two independent things and can be developed or even exchanged 
separately.

the point is that making bridge  betwen rebol script and librari 
in the way it is actually done is good for tiny simple library but 
very a tremendous work when it touch to heavy complicated library 
that intent to abstract from the os consept and give the same way 
to code on any OS/material. Mostly Opengl and GTK for example. Both 
libraries are heavy (lot of libs lot of struct lot of types lot of 
dependencies that needs a bridge too). For OPENGL you have two way 
to work or you make a OS based I/O and windowing system example gdi32.dll 
user32.dll for windows or xlib.so for Linux and  then exploite gl* 
function that are stored in the openGL.so/dll  or you use the related 
to opengl portable set of libraries to handle window drawing and 
Mouse/Keyboard events glut.dll/so. The fact that a librarie portable 
must be a library the abstract from the OS dependencies make them 
very complicated to handle. AS we don't have the same coding effort 
on library bridge coding than other language because many reasons 
in witch the fact that library loading is a Pro functionnality and 
maybe too because the system is not enought developped. It's easier 
to make a library bridge for a language when this language allows 
type creation and have based type in this language that feets with 
the one in C/C++

Regarding multitasking and REBOL, how far is it possible to go using

and it works quite well. I haven't done stress-test, so I have no 
real measurement, how effective it is, and what the performance is 
compared to other inter-task communication methods. I'm working on 
an OpenGL implementation, where OpenGL commands are sent from a REBOL 
task to an OpenGL server task (written in C), which will execute 
the OpenGL commands, so I'm about to get more experience in this. 
Both tasks will run on the same computer, but can easily be on different 
computers, of course.

are fewer than 10 bytes of communication. It may not be fast enough 
for games, but I hope, it's fast enough to make tools and fast OpenGL 
prototyping (trying out ideas).

https://jogl-demos.dev.java.net/- another java-opengl lib. with 
webstart and applet-demos.  Needs a little bit polishing, but i am 
not sure the flash-runtime has thatmch advantages.  Tested with firefox/linux.

so if its done Like I think, using R3 elixir should be VERY interactive. 
 and if that doesn't work, well, I can just use OpenGL later on.
Maxim:

If I decided to go ahead with OpenGL and Elixir, using GLASS as the 
design... what is left of REBOL but the syntax and the interpreter 
anyways?  I'd rather have the tool running on steroids without being 
tied to a chain.

also will be porting to OpenGL, but the high level coding won't change.

using this technique, I was able to do skining which is independent 
of the gui engine underneith.  one only has to support the aspects 
in his skin and the skins (and gui using them) remain valid, even 
though you are running on opengl or vid.

The engine will use liquid's flexible interpreted messaging overlayed 
on the other graph engine which I will use for scalability in sheer 
volume of connections and nodes I can allocate.  just a portion of 
the tree usually needs to be in RAM at any given time, and in fact, 
parts of processing tree can now reside on different computers since 
the graph engine is refered to... it should be quite fun to use.


this will be tied in to the OpenGL and scream core scene-description 
engine as one cohesive toolset.


in this system, the binary nodes will actually be optional and should 
be invisible when used from the rebol application's point of view.

if Cyphre can show that OpenGL can be compiled within (with a proof 
of concept demo, just to show that its actually possible),  for example.

I see no reason, why you can't make 3d games using OpenGL together 
with REBOL.  Eve Online is made with Python: http://www.eve-online.com/
Maxim:

humm. well how much of REBOL would we really be using in an OGL game 
with proper key support... none of view... so basically core with 
a huge stub over OpenGL and native event handling.

There are 2 OpenGL implementations for REBOL already. One by Cyphre, 
that require REBOL/Command (I think), and mine requiring GLServer 
(compiled C program, only for OS X so far).
Reichart:

Why not use OpenGL?  It seems your game primitives are just that...primitive. 
 A little physics, collision, sound, etc.   Nothing difficult.  IF 
you make it OpenGL, it can work on Mac, and even many Cell phones.


You might be able to write an abstraction layer so you can keep a 
lot of your Flash code in place.
