 This first Lab assignment is intended to get the Ogre3D environment started. Getting the development environment set up and configured can be a little tricky for the first time, so this Lab will be solely used to get the "Hello World" of Ogre3D built.\\
-There will be a paper hand out in the first lab class that will take you through the basic application step by step. I strongly encourage you to try to understand the steps not just writing it down like a zombie parrot, as the follow up Labs will all be built on top of the base you create in Lab 1.

 - Download and install C++ development environment, the instructions will assume you are using the [[http://www.microsoft.com/visualstudio/eng/downloads#d-2010-express|MS Visual C++ Express 2010 environment]], which you can get for free. You're free to use other environments or platforms as long as you take care of making it work on your own (with the help of the Internet).
-  - Download and install [[http://www.ogre3d.org/download/sdk|OGRE 1.9 SDK for Visual C++ 2010 (32-bit)]]. I recommend extracting this to a folder with a relatively short path and no spaces. E.g. into "C:\Development". You are free to use other versions, but be advised you will be rowing your own boat if problems arise :)

 ===== Lab Project =====
-You should now follow the hand out given to you by the instructor. For this Lab we will only do the sections 1 - 3 of the Ogre 3D beginners Guide. The rest will be covered in the next Lab assignment.\\
+You should now follow the guide from "Ogre3D 1.7 Beginners Guide by Felix Kerger" which you can get {{:public:t-gede-14-1:ogrestartup_ogre3d_1.7_beginners_guide_chapter_9_by_felix_kerger.pdf|Here}}.\\  For this Lab we will only do the sections 1 - 3 of the Ogre 3D beginners Guide.

-After line 2 in section 2 of the Guide, please add these lines to the code. Since the Ogre 1.9 default Scene Manager does not set the ambient light by default, we have to that our selves.
