Vertex
Shader
A Vertex Shader i s also GPU component
and i s also programmed using a specific

shaders, but are oriented to the scene
geometry and can do things like adding
cartoony s ilhouette edges to objects, etc.

Pixel Shader A Pixel Shader is a graphics function that
calculates effects on a per-pixel basis.
Depending on resolution, in excess of 2
mi l lion pixels may need to be rendered,
l i t, shaded, and colored for each frame,
at 60 frames per second.
8#q=what+is+a++pixel+shader
Pixel shader is to
upgrade the image
(room) clarity. By
shadeing in and
colouring in each frame
at 60 frames per
second.
Post
Processing
Pixel shaders are then used to apply
pos t-processing filters to the image
buffer before displaying it to the s creen.
Pos t-processing allows effects to be used
that require awareness of the entire
image (since normally each 3D object is
rendered in isolation). Such effects
include: High dynamic range rendering.
8#q=what+is+a++post+prossessing
Pos t processing is used
to enhance the clarity
of the game when
looking at something
from a di stance.
This image is a
good example
because it
shows Pixel
Shadeing for a
game.
This image is a
good example

Rendering Rendering is the process of generating an
image from a 2D or 3D model (or models
in what collectively could be called a
s cene file), by means of computer
programs.
http://en.wikipedia.org/wiki/Rendering_(
computer_graphics)
Rendering is the
process of taking the
picture from 2d to 3d
models. To generate a
final product.
Normal Map Normal mapping used to re-detail
s implified meshes. In 3D computer
graphics, normal mapping, or "Dot3
bump mapping", is a technique used for
faking the lighting of bumps and dents –
an implementation of bump mapping. It
i s used to add details without using more
polygons.
8#q=what+is+a+norrmal+map
Normal mapping is used
for faking the l ighting of
bumps and dents to
give i t a clearer
character.

Entity is a software architecture pattern that
implements concepts from Composition
over inheritance using a database-like
s tructure. Common ECS approaches are
highly compatible with Data-driven
programming techniques, and the two
approaches are often combined.

ponent_system
Enti ty i s a component
sys tem that implements
composition from
components.
UV Map UV mapping is the 3D modelling process
of making a 2D image representation of a

Procedural
Texture
A procedural texture is a computer-generated
image created using an
algorithm intended to create a realistic
representation of natural elements such
as wood, marble, granite, metal, s tone,
and others. Usually, the natural look of
the rendered result is achieved by the
usage of fractal noise and turbulence
functions.
8#q=what+is+a+procedural+texture
Procedure texture is to
input the natural
elements of the face of
the buildings to make i t
look more realistic.
Physics Computer animation physics or game
phys ics involves the introduction of the
laws of physics into a simulation or game
engine, particularly in 3D computer
graphics, for the purpose of making the
effects appear more real to the observer

Collision Col l ision detection typically refers to the
computational problem of detecting the
intersection of two or more objects.

tection
Col l ision is when two or
more objects collide
and this gives you the
effect of a crash in the
game.
Lighting Video games and computer-generated
movies and special effects benefit from
thi s as it creates more realistic s cenes
than with the more simplistic lighting
models used.
http://en.wikipedia.org/wiki/High-dynamic-
range_rendering
Lighting make the game
more realistic so it feels
l ike you are in the game
and i t feels real.
This image is a
good example
of using
lighting in
gaming
because it
shows the light
shining off the
water.

number of techniques to combat the
problems of aliasing in a sampled signal
such as a digital image or digital audio
recording.
http://en.wikipedia.org/wiki/Anti-al
iasing
Anti alising i s a
programme that
smoothes the edges to
give the game a more
definite line or surface.
LoD – Level
of Detail
Des cribes technology that is used to save
memory and processing power by using
lower detail models or textures for
objects in the distance. The Oblivion
game engine makes extensive use of
LOD, and the CS has some functions to
create and manipulate LOD objects.
