+ | * Notes from the Intel Software Network article on porting Smoke | ||
+ | ** No one has tried in on OSX. I would be very interested to know if you can get it to work. The biggest dependencies on Windows are DirectX and .NET. DirectX is used by Ogre3D... however, you should be able to use OpenGL instead of DirectX (OpenGL is just a separate plug for Ogre). The scripting system uses .NET... but you can feel free to disable the scripting project (it's not used in the demo at the moment). In the \bin folder you will find Smoke.gdf... delete the reference to the scripting system (you might need to remove it from Demo.cdf too). | ||
+ | ** Now here are the big challenges. There are a few systems that also depend on DX. These is SystemInput and SystemFire. SystemInput uses DirectX's input support. But that's easy enough to replace (or disable). SystemFire uses DirectX for some of the math calculations. Our math library should support all the needed functionality... we just didn’t have time to get all the DX out of there. | ||

Porting Intel's Smoke Game Demo to Linux
N.B. - If you edit by section (using the "edit" links next to the section heading) you will be much less likely to cause a Save conflict.
Latest News
Latest Issues
Known Bugs
- Smoke.cpp does not recognize Framework.cpp unless it is explicitly included.
- Even if Framework.h is included
Smoke Wiki Pages
Background Information
- BASH quick reference card - Media:bash-quick-ref.pdf
- Intel Software Network article
- FMOD Audio Engine
- Havok Physics Engine
- Ogre Rendering Engine Wiki
- TinyXML Main Site
- Intel's Thread Building Blocks
- (Post Other Links Here)
- Notes from the Intel Software Network article on porting Smoke
- No one has tried in on OSX. I would be very interested to know if you can get it to work. The biggest dependencies on Windows are DirectX and .NET. DirectX is used by Ogre3D... however, you should be able to use OpenGL instead of DirectX (OpenGL is just a separate plug for Ogre). The scripting system uses .NET... but you can feel free to disable the scripting project (it's not used in the demo at the moment). In the \bin folder you will find Smoke.gdf... delete the reference to the scripting system (you might need to remove it from Demo.cdf too).
- Now here are the big challenges. There are a few systems that also depend on DX. These is SystemInput and SystemFire. SystemInput uses DirectX's input support. But that's easy enough to replace (or disable). SystemFire uses DirectX for some of the math calculations. Our math library should support all the needed functionality... we just didn’t have time to get all the DX out of there.
Near Term Tasks
- Examine all of the documentation and build an annotated index of it in the wiki. Materials that are on-line already, e.g. the ones listed above, can have URLs and annotations. Ones that come with the source kit should just have titles, file system paths, and annotations. We don't want to upload those to the wiki without first checking with Intel about re-publishing their materials. (Nick)(Done!)
- Examine all of the source kit's directory tree and build an annotated map of it in the wiki. (Nick)(Done!)
- Examine all of the
#includes
inSmoke.cpp
and propose solutions for porting/converting/removing each of them. Remember that#includes
nest, we need to follow each thread starting with the ones inSmoke.cpp
. (Sam)(Done!) - Develop a Perl script/command line that converts back slashes to front slashes in directory paths. Use the feature that creates a backup of each changed file as it goes. (Sam)(Done!)
- Figure-out roughly how each of these works, what the dependencies are, etc. and propose a solution for porting/converting/removing each of them:
- Logging (Gil)
- Internal messages
- Debug messages, add the ability to
- Debugging (Gil)
getopt()
- EngineExecuteGDF (Gil)
main()
inSmoke.cpp
(Gil)(Done)- Argument processing in
Smoke.cpp
(Gil)(Done)
- Logging (Gil)
- Develop an ordered plan in the wiki (collective, in class on Friday)
- Modules
- Libraries
- Ogre/OpenGL replacing DirectX (Sam)
- Find and guard/eliminate .NET stuff (Nick)
- DirectX -> ? conversion for SystemInput and SystemFire (To Do before 2/26)
- Havoc (Nick)(Done(ish))(See Note*)
- Functionality
- Figure-out Doxygen and build a doc set (Sam)(Done!)
- Figure-out Make and construct the first simple Makefile that builds Smoke (To Do before 2/26)
- Note: Upon examining the code, I find that Havok is called, but the source for Havok is not given. We may have to inquire about and purchase the Linux Havok Libraries, as only the PC version Libraries are available for free (and only in binary).
