This lab, part A in particular, is heavily based on an Ogre physics example provided by Nikhilesh Sigatapu. Nikhilesh created a thin Bullet Physics Simulation wrapper for Ogre, which makes setting up physical objects very straight-forward. This wrapper is called btOgre and the example we will use is contained within that package. Other sources of information include of course the Bullet Physics Documentation and Wiki.

Discussion thread for this lab is here: Lab 7 Discussion Thread

The goal of this lab is to understand how you can integrate a physics simulation with Ogre and understand what such a simulation can provide.

Follow these steps to complete the lab project:

1. Download, Compile and Test Bullet Physics The Bullet physics simulation library comes with a number of OpenGL examples that demonstrate the capabilities of the library. Even if we intend to use this library with Ogre, you should first make sure you can compile and view these stand-alone examples. Do the following:
   1. Download Bullet 2.81 and for example place it next to your Ogre SDK. I suggest renaming the folder as bullet-2.81 as you are not likely to worry about specific revisions.
   2. Open and build <yoursdkfolder>\bullet-2.81\build\vs2010\0BulletSolution.sln
   3. Open a console in your <yoursdkfolder>\bullet-2.81 folder and execute App_HelloWorld_vs2010_debug.exe from the command line. You should see numbers printed out on the screen.
   4. Read through the source code for this example, located at <yoursdkfolder>\bullet-2.81\Demos\HelloWorld. Appreciate the fact that there are no graphics, and yet we have dynamic objects being simulated ;)
2. Create a New Ogre Project Create a new empty project called “Lab7” in the same way you have created new projects for other lab projects.

Upload your commented source files into Lab6 in MySchool (zip them up if more than one). The lab projects will not be graded, but their completion counts towards your participation grade.
