Set AL_LOWPASS_GAIN like EAX did under the hood.
Set the same filter via AL_DIRECT_FILTER on sources.
This should bring the overall sfx closer to EAX:
<kaan_> it sounds awesome
All infos provided by KittyCat from #openal.
The gain values are expressed as millibels in the .efx files
and need to be converted to normalized floating points.
Get the EAX4 EAXREVERBFLAGS_DECAYHFLIMIT from the "flags" token
and set AL_EAXREVERB_DECAY_HFLIMIT accordingly.
All infos provided by KittyCat from #openal, many thanks!
First attempt at porting the EAX reverb code to EFX.
This only works when the ALC_EXT_EFX extension is supported by
the OpenAL vendor (which is not the case for the OSX supplied
framework, use OpenAL soft instead).
The current stable version of OpenAL Soft (v1.13 as of this
writing) can barely handle this additional workload, current
master is highly recommended when using this feature.
We already link to OPENAL_LIBRARY further down.
Log some debug OpenAL info, mainly so OSX users can check they are not
using Apple's OpenAL. OpenAL Soft is recommended as it fixes many
issues.
I specify it as follows:
cmake -DOPENAL_LIBRARY=/usr/local/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/include -GXcode ../neo/
(because FindOpenAL.cmake prefers the /System frameworks)
Found another copy in renderer/Cinematic.cpp. Move the
newer implementation from renderer/Image_files.cpp in its
own file and use the libjpeg v8c license blob (which is where
this code comes from).
Adapt README too with the v8c license.
Don't link against SDLmain.[a|lib], always compile it.
We can use pure C MinGW cross compiled libraries with MSVC, and
this is the only static library used.
SDLmain.m does the bulk of the work for us, so get rid of
the DOOMController NSObject, move the quakeMain() contents to
main() and let SDL do its thing.
Add missing SDLMain and icon/resource files to generated .xcodeproj
Now builds on Lion in XCode4 with the 10.6 SDK using LLVM-GCC4.2.
Also tested on WinXP in VS 9 2008 Professional, I don't appear to have
broken anything there, stuff like MACOSX_BUNDLE_INFO_PLIST is
effectively ignored.
