Wow, you're quite right. No idea what happened there, I'm fixing
it now.

WIN32/MSVC++ INSTRUCTIONS

Open F4/Build/F4.dsw and build.

Your latest build is FUBAR to put it lightly.  It doesn't even
pretend to open the project files or will it open them manually in
VS6.  VS7 is not even worth trying as it is is FUBAR by itself.

Thought you might want to know.

Have a look at...

   F4/Services/Text/Src/font_factory.cpp: createTextureFont()

It's brute force, but it runs fairly quickly and produces great
results (as you can see).

To summarize:

- I use two textures, one for the glyphs and one for a mask, which
   indicates what parts of the texture have already been used.

- I sort the glyphs from largest to smallest.

- I try to keep the used space as close to a square as possible

Hope that helps. Let me know if you have any questions.

Version 0.3.1 is now available on the website at

	http://www.379.com/f4/

The big addition for this go-round is the new scene manager
package. It isn't optimized (no spatial partitioning mostly)
so it won't be useful for anything more than toy apps, but it
will let you know where I'm headed. I'm using it to visualize
3D data from a racetrack, so it is somewhat useful, even if
the FPS is low. I also added a sphere/tri-mesh collider using
Pierre Terdiman's OPCODE library, and improved the GNU build
scripts a bit.

Before the next release I need to get a 3D car on a 3D track
along with that 3D data, so I'll be trying to make the scene
API run a good deal faster. And as an aside, I've figured out
a way get rid of all of those SCRIPT_METHOD(...) macros, but
I'm not sure if that will make the next release or not, as it
involves a fair amount of new code behind the scenes.

As always, comments and criticisms welcome,

Jason

I've integrated Pierre Terdiman's OPCODE library into the
collider module. Only sphere/mesh tests work at the moment,
but I'll be adding more in future.

Other than a few minor fixes and more documentation, what's
in cvs now will be the 0.3.1 release. If you haven't been
keeping up, I've replaced the scene manager from the 0.2.x
releases and added some examples to show how to use it.

Jason

Just a quick FYI...I've worked out a prototype of a new scene
manager, and I've started to add code and docs to cvs. There
isn't much there yet but I'll be adding more over the next
several days. I've started using this API in our (racing)
game and it works pretty well. Let me know what you think.

Hello,

I've noticed that several people have joined the mailing list
since the 0.3 release, I just wanted to post a quick note to
let you know that this list is not dead.

I am making headway on a new high-level scene manager for F4,
though attempting to distribute it over a network makes me
rather dizzy. ;)

Any questions or comments, post them here and I'll be glad
to respond.

Jason

I have just released F4 version 0.3.0. This is mainly a cleanup 
release, so it doesn't add much new functionality (see the changelog 
below), but a lot of code has been shuffled around. A notable 
omission from this release is the scene management code (Node, 
etc.), which I have removed. The system used in 0.2.1 was too 
inflexible and too tighly coupled to the other services. This makes 
F4 more low-level, but more flexible as well.

I have also moved all of the source code into cvs on sourceforge, 
details are on the website.

My goal for the 0.3.x releases is to develop a distributed scene 
manager. If anyone has any brilliant ideas, insights, or references 
on the topic they would be willing to share, please let me know!

  -----

Version 0.3.0 (08-Apr-2002)
----------------------------

Removed as many interdependencies between services as possible.
The only engine code that is now truly "required" in an F4
application is the core and scripting services, the memory
manager, and the platform and math libraries. Most of the
changes in this version (and there are a *lot*) reflect this
newly enforced separation.

The scene graph system used in previous versions turned out to
be a dead end, and it has all been removed. This release does
not include a scene manager, specifically so I can make sure
that it can work independently of one. As a result, many of the
service interfaces have become more low-level.

The collision service now uses ODE under the hood and supports
all of the ODE shapes.

Overhauled the memory manager, added code to pool small (<4K)
allocations together into larger pages to improve performance
and reduce memory fragmentation. <memory.h> has been removed
from <core.h>, and must now be included manually in each file.
This allows it to always be last, avoiding conflicts.

Upgraded Lua to 4.1-work3, made some performance improvements
in the scripting interface.

A bunch of new work on the I/O service. Mounted filesystems
are now named and must be referenced explicitly during file
operations. Added OutputStream for data output, and IOFilter
for processing data as it moves to/from a stream.

Created a new Text service to handle both font generation and
rendering. Uses code from FreeType2 to generate new texture
fonts on the fly from TrueType or Type1 files, pretty cool.

The StdIO library now includes a .BMP importer, a .PNG
exporter, support for my own .4FNT format for texture fonts,
and a zlib filter for reading and writing compressed streams.

Created StdLib package and started added some basic shape
services for quick prototyping.

Took a first pass at the mouse event handling.

The physics package now provides a ContactPhysics service for
specifying the physical properties for a collision response.

The input mapping code has been moved out of System and into
the StdLib package. Additional parameters have been made
available to control the button<->axis conversions.

Another development snapshot is available at http://www.379.com/f4/

This one contains the new font generation (using FreeType) and text 
rendering services, as well as the start of the vertex buffer 
interface. Plus the usual assortment of miscellaneous changes and 
bug fixes. Plus a new version of NinjaFork that actually keeps score ;)

User input handling + physics = 0.3 release, soon.

Attn;PERSIENT/CEO

CONFIDENTIAL / URGENT BUSINESS PROPOSAL

It is with trust and confidence that I write toreveal this urgent business
proposal to you.
I was assigned by two of my colleagues to seek for a foreign partner,
who will assist us in providing aconvenient A/C in a designated bank
overseas for the transfer of USD30,000,000:00 (Thirty Million United
States Dollars Only), pending on ourarrival in your country for utilization
and disbursement of the fund withowner of the A/C. I was directed by
a friend DR. K.H KIM Former ForeignAffairs Minister to write you, in
fact I got your name and company's address from him, he assured me of
your immediate co-operation.

I am the chief Accountant of the Nigerian National Petroleum Corporation
(NNPC) on the 23rd of January 1999 my Corporation, awarded a contract
of
USD150,000,000:00 (One Hundred and Fifty MillionUnited State Dollars
Only) on the actual Contract sum worth US$120,000,000:00 only We only
inflated the sum worth with the intention of sharing the remaining balance
of US$30m (Thirty Million United State Dollars) among ourselves. Now
the actual contract has been successfullyexecutedand the actual contractors
have been paid their US$120,000,000:00 only in full leaving a balance
of US$30,000,000:00. Unknown to the governmentof Nigeria, which we now
want to transfer out of the country through aforeign partner in our favor
to make it as if payment for the contract has been completed. Since we
as government officials are not permitted by law to operate foreign bank
Accounts and secondly we cannot collect the money from the company's
bank Account because the Contract was undertaken by a foreign firm and
were paid through remittance totheir foreign Account.

 My colleagues and I have therefore agreed that if you /your company
can act asthe beneficiary of this fund (US$30,000,000:00) we will transfer
the money to your account and you will retain 30% of the total fund,
for the assistance rendered, while we set 10% aside for off setting of
all the expenses that may be incurred in advance by both parties during
the fund transferprocess. We are requesting you to co-operate with us
and provide a convenient account number in a designated bank where the
fund can be safely transferred into, since this is our only chance of
claiming the fund. Please note that we have been careful and have worked
out all the modalities for a smooth transfer of the fund to your chosen
or designated account before contacting you. We would therefore not want
youto expose this proposal to anybody for the purpose of security andit's
confidential nature. We also believe that you would not sit on ourmoney
when it is eventually transferred into your account as youreceive> your
30% share. Furthermore, be rest assure that this transaction is100% risk
free and the nature of your business has nothing to do with it. If the
proposal is acceptable to you please indicate your interest by contacting
us through the above stated e-mail address send us your account number
in a designated bank, address of the bank, your full name, fax and telephone
number. On confirmation of your acceptance more details about this transaction
will be given to you.Yours 

faithfully,

Chief Accountant CHRISTIAN MARK

Another 0.3 snapshot is on the website. This snapshots contains 
quite a few improvements to the script system, the new collision 
detection services, and the latest version of "NinjaFork!", a silly 
2D shoot-em-up written with F4/Lua.

Coming soon: text rendering and font generation (using FreeType) 
packages.

BTW - if there is a particular bit of 0.2.1 code that you are 
interested in getting into 0.3, let me know and I'll try to 
prioritize it. Unless I hear otherwise, I'm moving things over as I 
need them for my own work (and as Kane needs them for NF).

Enjoy,
Jason

I didn't realize that there was new entry on Flipcode today. I guess 
Kurt reads the sweng-gamedev list too. He's everywhere!

Jason

Hmm, are there people on the ML ?
I see new F4 development releases announced on Flipcode, but not on the
ML... Looks weird, uh ?

Just a thought.......

Pierre

Hi everyone.

Two little things:

1) In f4.h :
typedef char Int8;    ///< An 8 bit signed integer.
typedef unsigned char UInt8; ///< An 8 bit unsigned integer.
typedef short Int16;   ///< A 16 bit signed integer.
typedef unsigned short UInt16; ///< A 16 bit unsigned integer.
typedef int Int32;    ///< A 32 bit signed integer.
typedef unsigned UInt32;  ///< A 32 bit unsigned integer.

See anything weird ? The last line is probably supposed to be "unsigned int
UInt32" in sake of coherency. [of course it's not a real bug, but some
cosmetic stuff]

2) I had a link error when compiling in release mode. It was explicitely
linked to a missing lib in the Project Settings. I removed it, it worked. I
don't remember which lib it was but just check the differences between Debug
& Release settings and you'll find it.

F4 is a nice little engine, Jason.

I've finished my first pass on my vehicle dynamics stuff (separate 
project), so I can get back to the engine development for a while. Not 
that I ever really got away from it...I've got the core and script 
services running under Linux, along with a new memory manager. I had 
heard that pooling same sized allocations would give a net speedup over 
the standard allocators but I didn't realize how much: a test of 10M 
random allocations and frees took 9+ seconds instead of 28+.

I have also started a new page of stream-of-thought ramblings on the 
design ideas. I'm working on a new and improved scene/entity management 
scheme now. I'll be adding more over the next few days but you can see 
it now at http://www.379.com/f4/design.html. Thoughts and comments 
welcome as always.
