Update November 11, 2009

CFC and CFC GUI have been updated to 0.60 and 0.60.35 respectively. CFC runtime files

have

been updated. This thread has also been update to add information about the new file formats.

Changes:

- (CFC GUI) Support for new filenames (and categories) used in TF3D v2.5+

- Support for new file formats (read only, "replace" write is always in old format) used in TF3D v2.5+

- Support for new compressed formats that correspond to the new formats mentioned above

- (CFC GUI) If you are using this with 2.5, please do read the 2.5 specific notes (in the CFC GUI thread).

- At this time I STRONLY recommend patching Manila files manually instead of using the auto-patching! See the tech thread referenced below.

Update June 5, 2009

CFC and CFC GUI have been updated to 0.55 and 0.55.25 respectively. The CFC runtime files have

not

been updated. Changes:

- Better compression ratio (backwards compatible with old runtime)

- UltraHQ en/de-coding support (CFC)

- "Patch Manila on device" function has been improved to work-around the issue of Manila no longer starting that some people have (CFC-GUI)

Update April 20, 2009

CFC and CFC GUI have been updated. Many changes! For the changelog see the CFC GUI thead. The CFC runtime has also been updated to v0.50, so there is a new libgles_mn file required. See the cfc-support-dll zip attached a few posts down.

Update Feb 26, 2009

CFC and CFC GUI have been updated to 0.46.15. Fixed an issue with PNGs without alpha channel.

Update Jan 15, 2009

CFC Live Patch 0.45.01 has been released. You can run this tool on your phone to make your current Manila installation compatible with CFC compression.

See this post.

Update Jan 13, 2009

CFC 0.45 and CFC GUI 0.45.12 released.

CFC (core) changes:

- Heavily modified encoding algorithm. It is often slower but the quality should be much better. Please read this post!

CFC GUI changes:

- No longer freaks out if the wrong file attributes are set on some files

- Added background color selection

- Added tool to patch a complete Manila package for CFC compatibility and optimization

Also, non-technical discussion of CFC GUI (only) should go to this thread:

Update Jan 12, 2009

Yes I know, too many updates today!

CFC 0.42 attached. Was something weird going on with the encoding sometimes. Furthermore it seems like the encoding works great on the original files, but it drops the ball here and there with other files. Going to look into that ASAP and finetune the encoding algorithm!

Most important about this update is, CFC now also comes with a GUI!

Update Jan 12, 2009

CFC has been updated to version 0.4. Added features are:

- QTC -> PNG (+- 30% faster than 0.4b2)

- PNG -> QTC

- CFC -> QTC (finally)

- QTC padding

- QTC trimming

With QTC <-> PNG conversion now available from CFC, it seems the Compressonator is no longer needed!

Further EDIT: All posts updated.

Further EDIT: 0.41 added... There was a small bug in CFC compression in 0.4, it didn't always set PayloadSize correctly, which could create errors with padding/trimming.

Update Jan 8, 2009

CFC has been updated to version 0.3. It can now fully handle the RGB format as well. CFC compression has been slightly optimized. QTC and ATC headers are now completely written correctly.

This now also allows for larger than original images :)

Also lots of info in the first 6 posts has been updated to reflect these changes and add information.

Update Jan 7, 2009

Thanks to myself and D-MAN666, it seems the QTC format is now completely known!

Also today brings CFC compression for (W)VGA devices, if chefs choose to implement it. The needed stuff is here.

The CFC tool itself still needs an update (0.3 ?) to handle QTC/ATC_RGB conversion to ATC/ATC_RGB conversion (and back) and to decompress the CFC files. Donor headers won't be needed anymore then either in some cases (but they will remain handy in others!), and with that some parts of the first 5 posts will have to be rewritten as well (sigh...)

Note that some other parts of the first few posts are marked with changes. Look for the red letters.

Intro

As some of you may have seen, me, djboo, pcarvalho, "he who shall not be named" and several other enthousiasts have ported TouchFlo3D (to be specific, the version that came on my Raphael) to QVGA. A large part of this effort involved hacking into Manila/Mode9 and even OpenGL ES itself to get it operating decently, but after that, a lot of effort went into optimizing, which was largely done by scaling the images. While working on this, I encovered a lot of information and wrote quite a bit of code to 'get it done'. As always, a lot of it ultimately redundant, but we did pull it off! (barring some issues that are driver related).

Acknowledgements

Before continuing, people need to be acknowledged for their parts in this. I could hardly have done it alone. A lot of these credits go out to people involved in the TF3D QVGA porting, but also drivers porting, they all had a hand in this information being 'discovered', and hence are mentioned here.

-

djboo

Keeping all this stuff going. I looked at this stuff once when herg did an attempt, never really got involved, but because of him did get involved this time around. As he seems to be forgotten in the credits here and there, he's #1 in this thread!

-

pcarvalho

A bit of competition that led to great stuff. In the end, our intended methods of porting complement eachother nicely - 'my' part got it going, but the QVGA port didn't really shine 'til we did the other things 'his way' as well.

-

"he who shall not be named"

The anonymous HTC-CA hacker, about whom probably everybody knows who he is (it aint me ;)) Did some cracking work on this too.

-

The P3D Team

A bunch of them did a lot of testing

-

D-MAN666

Mentioned last but certiainly not least! Cracked the file format first, and generally found out and published a hell of a lot of information. Also the author of Manila Editor.

Requirements

For all this, you will need and/or want the following:

- "The Compressonator", image conversion/compression/viewer tool by ATI/AMD. You may need to sign up at the AMD website, but it is free of charge and I haven't received any spam from them yet. Update: The version of Compressonator on AMD's site is no longer able to do ATC. The correct version of Compressonator is attached to this post. Update: The Compressonator is now no longer strictly needed due to CFC being able to do the QTC en/decoding.

- "Manila Editor", Manila image editor. You will not be using this for the actual good stuff, but you may be using this for testing things quickly, and you will definitely want to use it for finding the files you actually want to replace. Update: no longer needed, use the CFC GUI instead!

- CFC, (attached), tool by yours truely to convert between QTC, ATC, CFC and PNG formats

- Knowledge of the Windows command line - Though CFC now comes with a GUI as well, yay!

- The files attached to this post. These are all the images from Manila (the version that came with my Raphael) converted to PNG by "The Compressonator". It's kind of a ***** to do, so if you want to save yourself some trouble, just see that post. VGA as well as (rescaled using Lanczos3) QVGA images are attached to that post. Update: this image packs need to be updated, will do some time

CFC download

Notice: you do not need the compressonator files to use CFC. They are just here in case you want to do things the old-school way :)
