NxOgreCube.png Introduction

In this tutorial you will learn where to obtain the latest version of NxOgre, BloodyMess, and how to set it up on your computer. This whole procedure is not that interesting, but like most SDK's and libraries it must be done. But, I can assure you, it won't take that long and you will soon enough be making full use of NxOgre. Let us begin.

NxOgreCube.png Downloading PhysX

As BloodyMess is based upon the nVidia PhysX physics engine, you will need to download the PhysX System Software along with the PhysX -SDK.

The PhysX System Software is required to run any software that makes use of the PhysX physics engine as it contains the runtime DLL's. Anyone who uses an application using PhysX and NxOgre will have to install the System Software.

For those who have a recent nVidia graphics card: The System Software may already be installed on your computer. You can find out by checking if the directory "AGEIA Technologies" exists in your Program Files directory.


The PhysX -SDK contains the header and linker files that are required for NxOgre to compile and work, along with the PhysX documentation, development tools, and samples. It is essential to install the PhysX -SDK in order to develop with NxOgre.

Both the -SDK and System Software (if required) can be downloaded from the links at the nVidia PhysX FAQ page. It is recommended that you install the PhysX -SDK to a path that does not contain spaces, such as c:/PhysXSDK/.

NxOgreCube.png Getting BloodyMess

In order to download the latest BloodyMess version, go to the NxOgre github.com repository and download the latest commit. Simply decompress the archive to a folder of your choice. It is again recommended that this folder not contain spaces, such as c:/bloodymess.

Older BloodyMess versions can be found on the BloodyMess release page, however the tutorials are likely to not 100%ly comply with these versions anymore due to some minor API breaking changes.

NxOgreCube.png Building BloodyMess

Once you have downloaded and installed the PhysX System Software and -SDK, and decompressed BloodyMess, you can build NxOgre. There are several different build configurations available. The two most important ones are the Debug and Release DLL's, but you can also build them as static.

With BloodyMess, there is also a totally new build configuration available referred to as Minimal. Building NxOgre as Minimal decreases the file sizes and contains some optimizations at the cost of not being able to make use of PhysX's cooking abilities with which you can dynamically create meshes or cloths at runtime.

BloodyMess comes with pre-built Visual Studio 8 and 9 solutions (.sln file) in the build/msvc folder where you extracted BloodyMess. Within the solution file are three projects:

  • NxOgre
  • GLUTRenderSystem
  • OGRE3DRenderSystem


The first is the core NxOgre project. The other two are specialized classes for different render systems. As you are most likely going to be using Ogre for your rendering system you may disregard the GLUTRenderSystem project which uses pure OpenGL.

To begin building NxOgre in Visual Studio simply go to Build->Build Solution or press F7 on your keyboard.

Once you have compiled the NxOgre and OGRE3DRenderSystem projects, you should have the DLL's, libraries, and includes all required to use NxOgre in your /sdk subfolder from where you extracted BloodyMess. That means you are ready to actually start using BloodyMess. Congratulations!

NxOgreCube.png Setting Up Your -IDE

To use NxOgre within a project you must tell your -IDE where to locate the BloodyMess libraries and include files . To do this, point your IDE's include directories as well as its linker directories to the /sdk folder located where you extracted BloodyMess.

Depending on your mode, you will also need to add the following files to your -IDE as linker dependencies (in addition to ones required by Ogre).

For debug mode:

  • NxOgre_Debug.lib
  • NxOgreOGRE3D_Debug.lib


For release mode:

  • NxOgre.lib
  • NxOgreOGRE3D.lib

NxOgreCube.png Conclusion

Well, that's it! You just set up everything on your computer in order to step in the great world of physics with BloodyMess and NxOgre. The only thing left for you to do is to go to the next tutorial and learn how to use NxOgre so you didn't go through this rather boring first tutorial for nothing!

  • "Derivative Work" means a work based upon the Work or upon the Work and other pre-existing works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which the Work may be recast, transformed, or adapted, except that a work that constitutes a Collective Work will not be considered a Derivative Work for the purpose of this License. For the avoidance of doubt, where the Work is a musical composition or sound recording, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered a Derivative Work for the purpose of this License.
  • "Licensor" means the individual or entity that offers the Work under the terms of this License.
  • "Original Author" means the individual or entity who created the Work.
  • "Work" means the copyrightable work of authorship offered under the terms of this License.

You must keep intact all notices that refer to this License and to the disclaimer of warranties. You may not distribute, publicly display, publicly perform, or publicly digitally perform the Work with any technological measures that control access or use of the Work in a manner inconsistent with the terms of this License Agreement. The above applies to the Work as incorporated in a Collective Work, but this does not require the Collective Work apart from the Work itself to be made subject to the terms of this License. If You create a Collective Work, upon notice from any Licensor You must, to the extent practicable, remove from the Collective Work any credit as required by clause 4(c), as requested. If You create a Derivative Work, upon notice from any Licensor You must, to the extent practicable, remove from the Derivative Work any credit as required by clause 4(c), as requested.
  • You may distribute, publicly display, publicly perform, or publicly digitally perform a Derivative Work only under the terms of this License, a later version of this License with the same License Elements as this License, or a Creative Commons iCommons license that contains the same License Elements as this License (e.g. Attribution-ShareAlike 2.5 Japan). You must include a copy of, or the Uniform Resource Identifier for, this License or other license specified in the previous sentence with every copy or phonorecord of each Derivative Work You distribute, publicly display, publicly perform, or publicly digitally perform. You may not offer or impose any terms on the Derivative Works that alter or restrict the terms of this License or the recipients' exercise of the rights granted hereunder, and You must keep intact all notices that refer to this License and to the disclaimer of warranties.

The above applies to the Derivative Work as incorporated in a Collective Work, but this does not require the Collective Work apart from the Derivative Work itself to be made subject to the terms of this License.
  • If you distribute, publicly display, publicly perform, or publicly digitally perform the Work or any Derivative Works or Collective Works, You must keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing: (i) the name of the Original Author (or pseudonym, if applicable) if supplied, and/or (ii) if the Original Author and/or Licensor designate another party or parties (e.g. a sponsor institute, publishing entity, journal) for attribution in Licensor's copyright notice, terms of service or by other reasonable means, the name of such party or parties; the title of the Work if supplied; to the extent reasonably practicable, the Uniform Resource Identifier, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and in the case of a Derivative Work, a credit identifying the use of the Work in the Derivative Work (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). Such credit may be implemented in any reasonable manner; provided, however, that in the case of a Derivative Work or Collective Work, at a minimum such credit will appear where any other comparable authorship credit appears and in a manner at least as prominent as such other comparable authorship credit.
