| | |
| Continue with your project or use an older version starting from lab2. | Continue with your project or create a new project from the template, you need to be able to move the camera. |
| | |
| For the bonus point you might have to replace the pk3 file ''/Ogre1.9_vc100/OgreSDK_vc10_v1-9-0 | |
| /media/packs/chiropteraDM.pk3'' **Use of course your own Ogre sdk path.** | |
| | |
| with this pk3 file: {{:public:t-gede-14-1:chiropteradm.zip| chiropteraDM.zip}} **Rename it back to chiropteraDM.pk3, make sure to change the extension of the file to pk3 not just the name** | |
| | |
| The original file in the OgreSdk folder seemed to be missing a few textures, for this one I replaced the missing textures with one colored textures. | |

| - <box green 100% | Bonus point>**Testing Another Scene Manager** The so called "world geometry" of a game is often considered static and can be highly optimized for rendering. One optimized format for representing a static world is the BSP level format used originally by id's Quake engine. Ogre can read worlds in this format and display them using the ''BspSceneManager''. To try this, add the following method in your application<code cpp> void loadQuakeMap() { | ===== Bonus ===== |
| | <box green 100% | **Manual Object**> Create a method that takes 3 parameters, |
| | <code cpp> |
| | // radius of the base of the cone |
| | // height of the cone |
| | // detail is the number of vertices around the base. |
| | void createCone(float radius, float height, int detail); |
| | </code> |
| | This method should create a cone mesh with the tools used in the lab. Extra kudos for those who get the object to cast shadows and have an okish normal mapping. |
| | You can use this material for the object |
