Product Overview

Smoke is a tech demo that showcases a framework to support n-way threading of game technologies. By properly threading a game it can have more accurate physics, smarter AI, more particles, and/or a faster frame-rate. Smoke demonstrates one way to achieve better games.

All of the source code for Smoke is available for download.

The demo includes:

  • N-way threaded framework using Intel® Threading Building Blocks
  • Physics simulation using Havok Physics™
    • Download a free copy of Havok PC (5.5 or greater) from www.havok.com
  • Graphics and scene management using Ogre3D
    • Complex meshes/shaders
    • Skeletal animation
    • Particle systems
  • Procedurally generated fire that spreads dynamically and realistically
  • 3D audio using FMOD
  • Artificial Intelligence controlled animals
  • Input and interactivity using DirectInput
  • Performance profiling
What's new with Release 1.2
  • Smoke now has a simpler build and builds with Visual Studio 2008 SP1
  • Fixed occasional crash when subdividing objects, after physics collision
  • Fixed a number of memory leaks and uses of uninitialized memory
  • Ambient lighting now lights the shaded side of objects
  • Smoke runs faster, mostly due to speedups in fire object code

Frequently Asked Questions

Q: Where can I get the source?

A: All the source is available.

Q: How do I build the source code?

A: There are build instructions included in the source code zip file under Smoke\docs.

Q: How do I see the advantages of threading?

A: While the demo is running you can toggle the number of active threads.

  • Press Ctrl+1 for 1 thread
  • Press Ctrl+2 for 2 threads
  • Press Ctrl+4 for 4 threads
  • Press Ctrl+x for maximum threads (depends on the CPU)

 

Q: What is the license?

A: You can read the license here. The goal is to allow developers to use the Smoke code written by Intel for any purpose (including derivative works) with no limitations or obligations.

Hello rocky92,

Hmm. You Demo.cdf is the right file to edit (as long as you didn't change Smoke.gdf to point to a different .cdf file). Make sure you added Geometry (position information) and Graphics (visual information) for the new entries. If you run the demo in Debug mode, it'll output an error if anything is formatted incorrectly in the xml files. If you are still having problems, then please send me an example of a new entry you added.

Thanks,
Orion

Thank you for the reply orion. Adding AI objects didn't seem to add more computational complexity though procedural fire system objects like fireballs and meteors did, which makes sense.
Could you give me some info on how you calculated the positions of the objects? Editing the .cdf files manually seems like a pain ;), especially keeping track of coordinates between systems. Is there any editor to easily drag and drop objects and edit a scene?

Hey, Orion!

Are you planning any new updates for Smoke?

Best regards,
Anruin

Has anybody successfully built Smoke in debug mode with Intel Compiler XE 12.1? I encountered an error saying "controlling expression is constant" about an ASSERT statement.
