* cache for low res (deactivating high res for now) * new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern) * introducing LZO and LZMA libs into extern (makefiles missing for now) * reducing memory usage after simulating for the frame ended (freeing temporary buffers) * splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index) * no color on gui anymore * fixing non-power-of-2 resolutions (hopefully) * fixing select-deselect of domain drawing bug * fixing drawobject.c coding style (making Ton happy) ;-) HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too) CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown! WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that. WARNING #2: File and cache format of smoke can be changed, this is not final!

I've created miniLZO for projects where it is inconvenient to
|
|
include (or require) the full LZO source code just because you
|
|
want to add a little bit of data compression to your application.
|
|
|
|
miniLZO implements the LZO1X-1 compressor and both the standard and
|
|
safe LZO1X decompressor. Apart from fast compression it also useful
|
|
for situations where you want to use pre-compressed data files (which
|
|
must have been compressed with LZO1X-999).
|
|
|
|
miniLZO consists of one C source file and three header files:
|
|
minilzo.c
|
|
minilzo.h, lzoconf.h, lzodefs.h
|
|
|
|
To use miniLZO just copy these files into your source directory, add
|
|
minilzo.c to your Makefile and #include minilzo.h from your program.
|
|
Note: you also must distribute this file (`README.LZO') with your project.
|
|
|
|
minilzo.o compiles to about 6 kB (using gcc or Visual C on a i386), and
|
|
the sources are about 30 kB when packed with zip - so there's no more
|
|
excuse that your application doesn't support data compression :-)
|
|
|
|
For more information, documentation, example programs and other support
|
|
files (like Makefiles and build scripts) please download the full LZO
|
|
package from
|
|
http://www.oberhumer.com/opensource/lzo/
|
|
|
|
Have fun,
|
|

|
P.S. minilzo.c is generated automatically from the LZO sources and
|
|
therefore functionality is completely identical

Appendix A: building miniLZO
|
|
----------------------------
|
|
miniLZO is written such a way that it should compile and run
|
|
out-of-the-box on most machines.
|
|
|
|
If you are running on a very unusual architecture and lzo_init() fails then
|
|
you should first recompile with `-DLZO_DEBUG' to see what causes the failure.
|
|
The most probable case is something like `sizeof(char *) != sizeof(long)'.
|
|
After identifying the problem you can compile by adding some defines
|
|
like `-DSIZEOF_CHAR_P=8' to your Makefile.
|
|
|
|
The best solution is (of course) using Autoconf - if your project uses
|
|
Autoconf anyway just add `-DMINILZO_HAVE_CONFIG_H' to your compiler
|
|
flags when compiling minilzo.c. See the LZO distribution for an example
|
|
how to set up configure.in.
