The purposeis to transform eachvertex's 3D positionin virtual space to the 2D coordinate at whichit appears on the screen. We would use this to add extra detail onto stuff suchas horses http://www.3dvelocity.com/reviews/6800ultra/technology /displacement.jpg
- 5. Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 5 GAME ENGINE S Pixel Shader Pixel shaders, also knownas fragment shaders, compute colour and other attributes ofeachfragment. The simplest kinds ofpixel shaders output one screen pixel as a colour value; more complex shaders with multiple inputs/outputs are alsopossible. Pixel shaders range from always outputting the same colour, to applyinga lighting value, to doing bump mapping, shadows, specular highlights, translucencyand other phenomena. Theycan alter the depthof the fragment. We would use this add extra detailinto environments http://assets.overclock.net.s3.amazonaws.com/4/4e/4e77 6cf7_vbattach2843.jpeg Post Processing The PostProcessVolume is a special type of volume that can be addedto a level and, because Unreal Engine 4 does not make use ofpost processing chains, these volumes are currentlythe onlywayto manipulate post processingparameters. The new system is not complete andwe will expose some programmability, but we want the common cases to be handled verywell bythe system. This makesit easier for artists/designers to use the systemandfor programmers to optimize it. https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProce ssEffects/index.html We would use this to add more detail into our work http://gamingdead.com/wp- content/uploads/2013/05/vlcsnap.jpg Rendering Rendering is the process of generating animage from a 2D or 3D model (or models inwhat collectivelycould be called a scene file), bymeans of computer programs. Also, the results of such a model canbe calleda rendering. We would use this to make the game look smoothand clean http://1.bp.blogspot.com/- xRWshgWFcPA/UrAEX6J7CKI/AAAAAAAAEj4/aeqvg_CVlao/ s1600/uncharted_2_among_thieves_8.jpg

We would use this to make like a pattern for the floor http://en.wikipedia.org/wiki/Procedural_texture#mediavie wer/File:Procedural_Texture.jpg Physics Computer animationphysics or game physics involves the introduction of the laws ofphysics intoa simulation or game engine, particularlyin 3D computer graphics, for the purpose of making the effects appear more real to the observer. Typically, simulationphysics is onlya close approximation to real physics, andcomputation is performedusing discrete values. We would tryto make sure the physics are goodso that the game doesn’t endupwith stuff flying http://img.gamefaqs.net/screens/9/8/b/gfs_49160_2_1.jp g

Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 8 Collision Collisiondetection typicallyrefers to the computational problem of detecting the intersectionof two or more objects. While the topic is most often associated withits use in videogames and other physical simulations, it also has applications inrobotics. We would make sure the collision is good sothat the player doesn’t end up going through walls http://www.swankworld.net/Games/PC/bigrigs/bigrigclip.j pg Lighting The waythe game lights the game upsothat there is light within the game. We would use lightingsothat we have shadows in the game which makes it so we have a bit of detail http://gamingbolt.com/wp-content/gallery/best-lighting- in-games/killzone-2-lighting.jpg AA – Anti- Aliasing Anti-Aliasingis a methodof foolingthe eye that a jagged edge is really smooth. Anti-Aliasingis often referred ingames andongraphics cards. In games especiallythe chance to smoothedges ofthe imagesgoes a long wayto creating a realistic 3D image onthe screen. Remember though that Anti-Aliasing does not actuallysmooth anyedgesof images it merelyfools the eye. Like a lot of things theyare onlydesigned to be good enough. If youcan't tell the difference thenthat's fine. Let’s take a look at the example belowto demonstrate the effects of Anti-Aliasing. http://www.pantherproducts.co.uk/index.php?pageid=antialiasing We would use this to make edges in the game look smoother and not too jagged when the user is playing http://solidlystated.com/content/2011/06/divinity2-anti- aliasing.jpg
